Enabling and disabling services during start up in GNU/Linux

Enabling and disabling services during start up in GNU/Linux

In any Linux distribution, some services are enabled to start at boot up by default. For example, on my machine, I have pcmcia, cron daemon, postfix mail transport agent ... just to name a few, which start during boot up. Usually, it is prudent to disable all services that are not needed as they are potential security risks and also they unnecessarily waste hardware resources. For example, my machine does not have any pcmcia cards so I can safely disable it. Same is the case with postfix which is also not used.

So how do you disable these services so that they are not started at boot time?

The answer to that depends on the type of Linux distribution you are using. True, many Linux distributions including Ubuntu bundle with them a GUI front end to accomplish the task which makes it easier to enable and disable the system services. But there is no standard GUI utility common across all Linux distributions. And this makes it worth while to learn how to enable and disable the services via the command line.

But one thing is common for all Linux distributions which is that all the start-up scripts are stored in the '/etc/init.d/' directory. So if you want to say, enable apache webserver in different run levels, then you should have a script related to the apache webserver in the /etc/init.d/ directory. It is usually created at the time of installing the software. And in my machine (which runs Ubuntu), it is named apache2. Where as in Red Hat, it is named httpd. Usually, the script will have the same name as the process or daemon.

Here I will explain different ways of enabling and disabling the system services.

1) Red Hat Method

Red Hat and Red Hat based Linux distributions make use of the script called chkconfig to enable and disable the system services running in Linux.

For example, to enable the apache webserver to start in certain run levels, you use the chkconfig script to enable it in the desired run levels as follows:

# chkconfig httpd --add
# chkconfig  httpd  on --level 2,3,5

This will enable the apache webserver to automatically start in the run levels 2, 3 and 5. You can check this by running the command:

# chkconfig --list httpd

One can also disable the service by using the off flag as shown below:

# chkconfig httpd off
# chkconfig httpd --del

Red Hat also has a useful script called service which can be used to start or stop any service. Taking the previous example, to start apache webserver, you execute the command:

# service httpd start

and to stop the service...

# service httpd stop

The options being start, stop and restart which are self explanatory.

2) Debian Method

Debian Linux has its own script to enable and disable services across runlevels. It is called update-rc.d. Going by the above example, you can enable apache webserver as follows:

# update-rc.d apache2 defaults

... this will enable the apache webserver to start in the default run levels of 2,3,4 and 5. Of course, you can do it explicitly by giving the run levels instead of the "defaults" keyword as follows:

# update-rc.d apache2 start 20 2 3 4 5 . stop 80 0 1 6 .

The above command modifies the sym-links in the respective /etc/rcX.d directories to start or stop the service in the destined runlevels. Here X stands for a value of 0 to 6 depending on the runlevel. One thing to note here is the dot (.) which is used to terminate the set which is important. Also 20 and 80 are the sequence codes which decides in what order of precedence the scripts in the /etc/init.d/ directory should be started or stopped.

And to disable the service in all the run levels, you execute the command:

# update-rc.d -f apache2 remove

Here -f option which stands for force is mandatory.

But if you want to enable the service only in runlevel 5, you do this instead:

# update-rc.d apache2  start 20 5 . stop 80 0 1 2 3 4 6 .

3) Gentoo Method

Gentoo also uses a script to enable or disable services during boot-up. The name of the script is rc-update . Gentoo has three default runlevels. Them being: boot, default and nonetwork. Suppose I want to add the apache webserver to start in the default runlevel, then I run the command:

# rc-update add apache2 default

... and to remove the webserver, it is as simple as :

# rc-update del apache2

To see all the running applications at your runlevel and their status, similar to what is achieved by chkconfig --list, you use the rc-status command.

# rc-status --all

4) The old fashioned way

I remember the first time I started using Linux, there were no such scripts to aid the user in enabling or disabling the services during start-up. You did it the old fashioned way which was creating or deleting symbolic links in the respective /etc/rcX.d/ directories. Here X in rcX.d is a number which stands for the runlevel. There can be two kinds of symbolic links in the /etc/rcX.d/ directories. One starts with the character 'S' followed by a number between 0 and 99 to denote the priority, followed by the name of the service you want to enable. The second kind of symlink has a name which starts with a 'K' followed by a number and then the name of the service you want to disable. So in any runlevel, at any given time, for each service, there should be only one symlink of the 'S' or 'K' variety but not both.

So taking the above example, suppose I want to enable apache webserver in the runlevel 5 but want to disable it in all other runlevels, I do the following:

First to enable the service for run level 5, I move into /etc/rc5.d/ directory and create a symlink to the apache service script residing in the /etc/init.d/ directory as follows:

# cd /etc/rc5.d/
# ln -s /etc/init.d/apache2 S20apache2

This creates a symbolic link in the /etc/rc5.d/ directory which the system interprets as - start (S) the apache service before all the services which have a priority number greater than 20.

If you do a long listing of the directory /etc/rc5.d in your system, you can find a lot of symlinks similar to the one below.

lrwxrwxrwx  1 root root 17 Mar 31 13:02 S20apache2 -> ../init.d/apache2

Now if I start a service, I will want to stop the service while rebooting or while moving to single user mode and so on. So in those run levels I have to create the symlinks starting with character 'K'. So going back to the apache2 service example, if I want to automatically stop the service when the system goes into runlevel 0, 1 or 6, I will have to create the symlinks as follows in the /etc/rc0.d, /etc/rc1.d/, /etc/rc6.d/ directories.

# ln -s /etc/init.d/apache2 K80apache2

One interesting aspect here is the priority. Lower the number, the higher is the priority. So since the starting priority of apache2 is 20 - that is apache starts way ahead of other services during startup, we give it a stopping priority of 80. There is no hard and fast rule for this but usually, you follow the formula as follows:

If you have 'N' as the priority number for starting a service, you use the number (100-N) for the stopping priority number and vice versa.

Configure & test new software or patches in an isolated environment
Automate tasks for software development and testing
Demonstrate multi-tier configurations on a single PC

Use Multiple Operating Systems Concurrently on the Same PC

VMware Workstation 6.5 makes it simple to create and run multiple virtual machines on your desktop or laptop computer. You can convert an existing physical PC into a VMware virtual machine, or create a new virtual machine from scratch. Each virtual machine represents a complete PC, including the processor, memory, network connections and peripheral ports.

VMware Workstation lets you use your virtual machines to run Windows, Linux and a host of other operating systems side-by-side on the same computer. You can switch between operating systems instantly with a click of a mouse, share files between virtual machines with drag-and-drop functionality and access all the peripheral devices you rely on.

Take Snapshots & Videos of your Virtual Machines

With Workstation, you can take a “snapshot” that preserves the state of a virtual machine so you can return to it at any time. Snapshots are useful when you need to revert your virtual machine to a prior, stable system state. Workstation displays thumbnails of all your snapshots on a single screen, making it easy for you to track and revert to a previously saved snapshot.

You can even use Workstation 6.5 to record and play video files that capture all changes to a virtual machine over a period of time. This function is exclusive to VMware Workstation and is incredibly useful for software debugging, Help Desk forensics, sales demonstrations and training.

Split & Join Files + ubuntu

2009-07-08T14:22:00.001+07:00

Posted in command tagged Split at 12:19 pm by bearisusanto

We have a file which size is too big to save in USB Flash drive.
To split it to be a small size so its fit to store in USB is easy in linux platform, use “split” command which has been bundled in GNU Coreutils.

1. As example, we have an iso file (ubuntu-8.04-desktop-i386.iso) which size is 699 Mb
root@hardy:/home/bearisusanto/test# ls -alh
total 700M
-rwx—— 1 bearisusanto root 700M 2008-06-02 03:22 ubuntu-8.04-desktop-i386.iso2. Before doing split process, first make MD5 file from ubuntu-8.04-desktop-i386.iso for ensuring that there is not a change for the file when its join again
root@hardy:/home/bearisusanto/test# md5sum ubuntu-8.04-desktop-i386.iso > MD5SUM.txt
root@hardy:/home/bearisusanto/test# cat MD5SUM.txt
8895167a794c5d8dedcc312fc62f1f1f ubuntu-8.04-desktop-i386.iso

3. For splitting ubuntu-8.04-desktop-i386.iso to be a file which the size maximal 400Mb for each file, we type the command
root@hardy:/home/bearisusanto/test# split -d -b 400m ubuntu-8.04-desktop-i386.iso ubuntu-8.04-desktop-i386.iso.part

4. If we check in the directory, there is two 2 which is the result from splitting process
-rwx—— 1 bearisusanto root 700M 2008-06-02 03:22 ubuntu-8.04-desktop-i386.iso
-rw-r–r– 1 root root 400M 2008-10-31 23:13 ubuntu-8.04-desktop-i386.iso.part00
-rw-r–r– 1 root root 300M 2008-10-31 23:13 ubuntu-8.04-desktop-i386.iso.part01

5. To join the two file to be one file as the same with the original file, we use “cat” command but the original have to be deleted first.
root@hardy:/home/bearisusanto/test# rm ubuntu-8.04-desktop-i386.iso
root@hardy:/home/bearisusanto/test# cat ubuntu-8.04-desktop-i386.iso.part00 ubuntu-8.04-desktop-i386.iso.part01 > ubuntu-8.04-desktop-i386.iso

6. For ensuring that there is no difference with the original file, we have to validate with using MD5SUM.txt which have made for the first time.
root@hardy:/home/bearisusanto/test# md5sum -c MD5SUM.txt
ubuntu-8.04-desktop-i386.iso: OK

How to: Fix Yahoo Problem in Pidgin

Step-by-step tutorial with screenshots

By Marius Nestor, Linux Editor

21st of June 2009, 17:15 GMT

Adjust text size:

Two days ago, Yahoo! Inc. did something to its messenger servers, something that practically blocked all the Linux IM clients, such as Pidgin, Kopete, Empathy or GyachI. While many of us thought it might be an ISP issue, some very smart people found out the truth: Yahoo! changed the login method! However, at this moment (June 21, 2009), none of the aforementioned Instant Messenger clients for Linux can connect with the Yahoo protocol. This is, of course, not the first time when it happens, and Linux users are treated like outsiders. But, let's not start again with the endless question “Why Yahoo! doesn't update the Linux client?” and let's fix the problem (like we always do).

Below is a step-by-step tutorial for all Ubuntu users that want to connect with their friends via the Yahoo protocol, using the Pidgin Instant Messenger. Why Ubuntu? Because it appears that it is the most popular Linux operating system these days and because there are already packages available for it. Other Linux users can grab the Pidgin 2.5.7 sources or DEB packages (32-bit and 64-bit) right now from Softpedia.

· Right click HERE and choose the "Save Link As..." option. Save the key file on your desktop.

· Go to System -> Administration -> Software Sources...

Enter your password if asked. Go to the second tab, "Third-Party

Software," click on the "Add" button, and paste the line below for your Ubuntu distribution, in the "APT line" field...

Ubuntu 9.10

deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu karmic main

Ubuntu 9.04

deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu jaunty main

Ubuntu 8.10

deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu intrepid main

· Now go to the fourth tab, "Authentication," click the "Import Key File" button, navigate to the location where you've just saved the key file (usually, it is File System/home/YOURUSERNAME/Desktop) and double click it. You will immediately see a new entry called "A1F196A8 2009-01-20 Launchpad PPA for Pidgin Developers".

· Click the “Close” button, then the “Reload” one and wait for the application to close!

· Go to System -> Administration -> Update Manager...

...and update Pidgin to the new version!

Close Pidgin if it was running during the update process and open it again. Yahoo should connect immediately now. And the best part is that your Ubuntu machine will always be updated with the latest versions of the Pidgin messenger, from now on!

Pidgin 2.5.7 on Ubuntu 9.10 Alpha

Alternative Method:

This is for those that can not upgrade to Pidgin 2.5.7 or don't want to.

· Open Pidgin and go to Accounts -> Manage Accounts...

· Click on the Yahoo account and then on the "Modify" button...

· Click on the "Advanced" tab and paste the following line in the "Pager server" field...

cn.scs.msg.yahoo.com

Using recovery console:“Invalid Boot.ini” hoặc “Windows could not start” ở Windows XP

2009-06-19T23:50:00.000+07:00

Using recovery console:“Invalid Boot.ini” hoặc “Windows could not start” ở Windows XP: Khắc phục lỗi “Invalid Boot.ini” hoặc “Windows could not start” ở Windows XP - 13/12/2006 9h:35

Máy tính của bạn đang chạy “ngon lành”, tự nhiên vào một buổi “trái gió trở trời” nó không khởi động nữa mà hiện lên một thông báo “lạnh lùng”: Invalid Boot.ini hay Windows could not start because the following file is missing or corrupt: Windows\System32\Hall.dll, bạn sẽ làm gì?

Tới đây thì mọi chuyện trở nên tệ hại vì máy không khởi động vào Windows được nữa mà luôn luôn xuất hiện những báo lỗi đó mỗi lần khởi động máy. Có lẽ bạn sẽ nghĩ đến việc phải cài lại toàn bộ máy tính, nhưng bạn hãy khoan làm công việc “đau khổ” đó, hãy thử cách dưới đây xem sao, có thể sẽ giúp bạn “gỡ một bàn thua trông thấy” đấy:

1- Ở màn hình đầu tiên khi bạn khởi động máy tính, nhấn các phím Ctrl, Esc, Delete hoặc các phím từ F1 đến F12 sao cho cửa sổ cấu hình BIOS hiện ra. Thay đổi lại thứ tự khởi động đầu tiên là ổ đĩa CD-ROM hoặc DVD-ROM và lưu lại thiết lập.

2- Đưa đĩa nguồn Windows XP vào ổ đĩa và khởi động lại máy tính.

3- Khi bạn thấy thông báo “Press any key to boot from CD” xuất hiện thì hãy nhấn một phím bất kỳ để máy tính khởi động từ đĩa CD Windows XP.

4- Chờ trong giây lát và bạn sẽ thấy màn hình thông báo “Welcome to Setup” hiện ra, nhấn phím R để chạy trình Recovery Console. Tại đây, nếu bạn muốn khởi động máy lại mà không thay đổi gì thì chỉ cần nhấn phím Enter. Nếu máy bạn được thiết lập để chạy nhiều hệ điều hành thì hãy chọn một cái để dùng trình Recovery Console, tiếp theo gõ mật khẩu administrator và nhấn Enter.

5- Tại dấu nhắc lệnh, bạn gõ bootcfg /list và nhấn Enter. Danh sách các mục trong file Boot.ini sẽ hiện lên màn hình.

6- Tại dấu nhắc lệnh tiếp theo, bạn gõ bootcfg /rebuild và nhấn Enter. Lệnh này sẽ quét toàn bộ ổ đĩa cứng xem bạn đang dùng những hệ điều hành nào Windows XP, Windows 2000 hay Windows NT và sau đó nó sẽ hiển thị kết quả cho bạn thấy.

7- Tiếp theo bạn sẽ nhận một số thông báo chẳng hạn như dưới đây khi máy đang dùng Windows XP (nếu bạn đang dùng hệ điều hành khác thì cũng không khác nhau mấy):

- Khi gặp thông báo dưới đây thì bạn chỉ cần nhấn Y.

Total Identified Windows Installs : 1

[1] C:\Windows

Add installation to boot list? (Yes/No/All)

- Khi gặp thông báo “Enter Load Identifier”, bạn hãy gõ vào tên hệ điều hành mà bạn đang dùng (Microsoft Windows XP Professional hoặc Microsoft Windows XP Home Edition) và nhấn Enter.

- Khi gặp thông báo “Enter OS Load option”, bạn hãy gõ vào /fastdetect và nhấn Enter.

8- Tiếp theo, bạn gõ Exit và nhấn Enter để thoát khỏi Recovery Console. Bây giờ, máy tính của bạn sẽ khởi động lại và Windows sẽ chạy “ngọt ngào” lại như ngày nào. Chúc bạn thành công!

so, if you expect to start ldap with non-root, you must change the port of ldap > 1024. In this case, i'm using 1025 for my ldap .

You do realise that doing this will cause gettext dependancies to fail

This is the correct solution. Unfortunately, also one of the slowest.

Apache server response codes

2009-03-24T11:21:00.000+07:00

Apache server response codes

Introduction

Whenever a user sends a request to a server, a process called a ‘handshake’ begins where the server and your computer communicate and the server makes sure it can accommodate what your user has requested of it. This means being able to make the connection between the two computers and then completing the transfer of data.

Headers are short fragments of text which are generated by servers to hold information pertaining to each transfer as it occurs. There are four kinds of headers:

General

This holds information about the client (user), the server itself and the protocol being used (like http or ftp).
Entity This holds information about the data that is being transferred.

Request

This holds information about the allowable formats and parameters for the transfer.

Response

This is sent out by the server at the end of a transfer, and includes detailed information, in code form, on the outcome of the transfer.

Response Codes

As a web surfer you've probably become familiar with the dreaded 404 error message and the 500 internal server error.

If you get a 404 make sure your link is correct. Case does matter.A 500 Error is the result of a misconfigured CGI script or a misconfigured .htaccess file,. These are the most well-known server response codes, but there are many more. These numerical codes are grouped — the low numbers are generally ‘good’, and operate silently, while anything over 400 is definitely bad news and will be reported to the user in the form of an error message.

Error Code	Explanation
100-199	Silent Response Codes that signify that a request has been received and is currently being processed.
100	The request has been completed and the rest of the process can continue.
101	The user's request to switch protocols (like from FTP to HTTP) was accepted.
200-299	Silent codes that confirm that requests have completed successfully.
200	Ok — the file which the client requested is available for transfer. This is the response code you want to see all of your users receiving.
201	When new pages are created by posted form data or by a CGI process, this is confirmation that it worked.
202	The client's request was accepted, though not yet processed.
203	The information contained in the entity header is not from the original site, but from a third party server.
204	If you click a link which has no target URL, this response is elicited by the server. It's silent and doesn't warn the user about anything.
205	This allows the server to reset any content returned by a CGI.
206	Partial content — the requested file wasn't downloaded entirely. This is returned when the user presses the stop button before a page is loaded, for example.
300-399	A redirection is occurring from the original request.
300	The requested address refers to more than one file. Depending on how the server is configured, you get an error or a choice of which page you want.
301	Moved Permanently — if the server is set up properly it will automatically redirect the reader to the new location of the file.
302	Found — page has been moved temporarily, and the new URL is available. You should be sent there by the server.
303	This is a "see other" SRC. Data is somewhere else and the GET method is used to retrieve it.
304	Not Modified — if the request header includes an 'if modified since' parameter, this code will be returned if the file has not changed since that date. Search engine robots may generate a lot of these.
400-499	Request is incomplete for some reason.
400	Bad Request — there is a syntax error in the request, and it is denied.
401	The request header did not contain the necessary authentication codes, and the client is denied access.
402	Payment is required. This code is not yet in operation.
403	Forbidden — the client is not allowed to see a certain file. This is also returned at times when the server doesn't want any more visitors.
404	Document not found — the requested file was not found on the server. Possibly because it was deleted, or never existed before. Often caused by misspellings of URLs.
405	The method you are using to access the file is not allowed.
406	The requested file exists but cannot be used as the client system doesn't understand the format the file is configured for.
407	The request must be authorised before it can take place.
408	Request Timeout — the server took longer than its allowed time to process the request. Often caused by heavy net traffic.
409	Too many concurrent requests for a single file.
410	The file used to be in this position, but is there no longer.
411	The request is missing its Content-Length header.
412	A certain configuration is required for this file to be delivered, but the client has not set this up.
413	The requested file was too big to process.
414	The address you entered was overly long for the server.
415	The filetype of the request is unsupported.
500-599	Errors have occurred in the server itself.
500	Internal Server Error — nasty response that is usually caused by a problem in your Perl code when a CGI program is run.
501	The request cannot be carried out by the server.
502	Bad Gateway — the server you're trying to reach is sending back errors.
503	Temporarily Unavailable — the service or file that is being requested is not currently available.
504	The gateway has timed out. Like the 408 timeout error, but this one occurs at the gateway of the server.
505	The HTTP protocol you are asking for is not supported.

Using syslog or syslog-ng with slapd for OpenLDAP logging

OpenLDAP Quick Tips: Using syslog or syslog-ng with slapd for OpenLDAP logging

Friday, November 14. 2008

Hi All,

Here's my third tip in the "OpenLDAP Quick Tips" series:

"You want to enable logging via syslog or syslog-ng for your directory server":

For syslog, depending on your distro, you would edit /etc/syslog.conf or /etc/rsyslog.conf:

CODE:

# LDAP^[?] logs LOCAL4.* -/var/log/openldap.log

and then restart syslog/rsyslog:

CODE:

/etc/init.d/syslog restart

For syslog-ng, the following will work:

CODE:

source s_all { unix-stream("/dev/log"); internal(); }; destination d_ldap { file("/var/log/ldap^[?].log"); }; filter f_syslog { not facility(auth, authpriv) and not match(slapd); }; filter f_ldap { match("slapd"); }; log { source(s_all); filter(f_syslog); destination(d_syslog); }; log { source(s_all); filter(f_ldap); destination(d_ldap); };

You can also add:

CODE:

options { sync(n); };

and then restart as per your distro tools.

Thanks,

Gavin.

vista + mbr + grub

2009-03-16T21:35:00.001+07:00

So you can boot XP and Ubuntu completely, just not Vista?
This is not a grub error or you wouldn't get a Welcome screen.
Vista needs to be repaired. The first step to try is Testdisk
because the second step of using Vista's Startup Repair makes
some more work of restoring the Ubuntu grub menu to the MBR.

---------------------------------------------------------

I borrowed this advice from meierfra about using
Testdisk. sda is the first drive and sdb is the second drive and so on.

"You might try testdisk to rebuild the Boot sector:

Code:

sudo apt-get install testdisk
sudo testdisk /dev/sda

Choose "proceed" on the first screen, then
"intel"
"advanced",
Select the Windows partition (although it should be selected already) and choose
"boot"
"RebuildBS"

--------------------------------------

RebuildBS uses a backup of your boot sector. If the backup and
the current boot sector are not identical then you want to use
Testdisk to restore the backup (maybe it says write).

If you have a Vista OEM recovery cd, rather than a Vista install cd

Hướng dẫn cài đặt Wireless-G Broadband Router WRT54GS

2009-01-14T08:37:00.000+07:00

Hướng dẫn cài đặt Wireless-G Broadband Router WRT54GS

Hướng dẫn cài đặt Wireless-G Broadband Router WRT54GS

Hướng dẫn cài đặt Wireless-G Broadband Router WRT54GS

WRT54GS hỗ trợ một giải pháp tất cả trong một, chia sẻ kết nối Internet, 4 cổng chuyển mạch, hỗ trợ tính năng điểm truy nhập với tốc độ được tăng 35% so với chuẩn-G. Hỗ trợ các tính năng bảo mật cao cấp: mã hoá không dây WPA2, 802.11x, lọc địa chỉ MAC, tường lửa SPI...

1. Cài đặt WRT54GS như một thiết bị định tuyến
Để cài đặt WRT54GS như một thiết bị định tuyến bạn có thể thực hiện theo các bước sau:
Bước 1: Thay đổi địa chỉ của máy tính theo dải địa chỉ của WRT54GS
Bước 2: Truy nhập vào cấu hình thiết bị qua giao diện web, mở trình duyệt web và vào địa chỉ 192.168.1.1 (địa chỉ mặc định của thiết bị), bạn sẽ được yêu cầu vào Uername và Password mặc định là admin và admin.
Bước 3: Sau khi vào Username và Password bạn sẽ thấy một giao diện như hình phía dưới.
- Chọn chế độ PPPoE và vào Username và Password mặc định là admin và admin
- Nếu bạn muốn WRT54GS cấp địa chỉ IP động cho các máy tính hãy kích chọn Enable tính năng DHCP Server

Chỉ bằng một số bước đơn giản trên là bạn đã cài đặt xong WRT54GS như một thiết bị định tuyến làm nhiệm vụ định tuyến mạng LAN của bạn ra ngoài Internet.

2. Cài đặt tính năng không dây
- Lựa chọn mục Wireless trên giao diện cấu hình bạn sẽ thấy một cửa sổ như hình dưới.
- Tại mục Basic Wireless Settings bạn có thể để mặc định như ban đầu mà không cần thay đổi

- Để thiết lập bảo mật cho mạng không dây bạn chọn Wireless Security và lựa chọn một công nghệ mã hoá phù hợp với mạng của bạn (trong phần này chúng tôi hướng dẫn các bạn thiết lập bảo mật WEP, 64 bits 10hex digits). Các bạn có thể tham khảo hình dưới.

3. Thiết lập máy chủ web, mail...hay một ứng dụng bất kỳ ra ngoài Internet
Bước 1: Trước khi cài đặt tính năng DMZ bạn cần phải đăng ký một tên miền trên www.dyndns.com, kích hoạt tính năng DDNS trên thiết mà bạn có thể tham khảo như hình dưới.

Bước 2: Chọn Application & Gaming -> DMZ -> Enable. Sau đó bạn vào địa chỉ của máy chủ cần đưa ra ngoài Internet

Sau các bước trên các bạn đừng quên kích chọn Save Settings để lưu lại cấu hình đã cài đặt ở từng mục. Khi này các bạn đã có thể chạy các ứng dụng mà mình đã cài đặt.

Chúc bạn vui !!![right][i]Nguồn từ: Cộng Đồng Teen Việt Online - http://Teenv.Net/[/i][/right]

FreeBSD の ports を使って eclipse を作ろうとした。しかし、VM の初期化に失敗して全然先に進まない。

Stop in /usr/ports/java/eclipse.
$ make
$ /usr/ports/java/eclipse.

少し問題を追跡したところ、ビルドの為の ant を起動する時に、Java のヒープサイズが大きすぎるのが原因らしい。そこで、-Xmx の値を 1000M から 500M に少なくしたら、問題なくインストールが完了した。


$ vi /ports/tmp/ports/java/eclipse/work/build
#!/bin/sh

#ANT_OPTS=-Xmx1000M; export ANT_OPTS
ANT_OPTS=-Xmx500M; export ANT_OPTS

なお、ports をコンパイルしているディレクトリが /ports/tmp なのは、WRKDIRPREFIX=/ports/tmp を /etc/make.conf で設定しているからである。

from links the answer from Jason Hale

Solution:

This is a known problem with flex and kdesdk. See the following thread on the kde-freebsd mailing list: http://mail.kde.org/pipermail/kde-fr...er/003894.html
You can try to apply the following patch to the textproc/flex port: http://mail.kde.org/pipermail/kde-fr...ttachment.diff

# cd /usr/port/textproc/flex
#patch < /path/to/patch #pkg_delete -fx flex #make install clean

Alternatively, just build KDE without kdesdk.

relabel files + dirs + selinux

2008-12-11T15:01:00.000+07:00

Four main commands are used to relabel file-related objects: chcon(8), restorecon(8),setfiles(8), and fixfiles(8). All these commands relabel files, but they each have a specific use. Typically, chcon and restorecon are used for small labeling changes, whereas setfiles and fixfiles are used for larger changes.

The chcon command sets the same security context, or a portion of a security context, for one or more files based on user input. It is the most basic labeling command and its use is analogous to chmod(1). For instance, consider the following example:

$ mkdir public_html
$ ls -dZ public_html/
drwxrwxr-x  joe joe joe:object_r:user_home_dir_t public_html/
$ chcon -t httpd_user_content_t public_html/
$ ls -dZ public_html/
drwxrwxr-x  joe joe joe:object_r:httpd_user_content_t public_html/

In this example, we changed the security context of a newly created directory, which was automatically assigned the security context joe:object_r:user_home_dir_t, to joe:object_r:httpd_user_content_t. The -t option alone specifies that the type of file should be changed while the rest of the security context is retained.

The restorecon command is similar to chcon but sets the security context of file-related objects based on the default file context files for the current policy. The user, therefore, does not specify a security context. Instead, restorecon matches the filename with an entry in the file contexts files and applies the specified security context. In some sense, it is restoring the correct security context. For example, consider the following:

$ mkdir public_html
$ ls -Zd public_html/
drwxrwxr-x  joe joe joe:object_r:user_home_dir_t public_html/
$ /sbin/restorecon public_html/
$ ls -Zd public_html/
drwxrwxr-x  joe joe user_u:object_r:httpd_user_content_t public_html/

This example is functionally the same as the previous example using chcon but only because the file context files for this policy has the following entry:

/home/[^/]*/public_html(/.+)? user_u:object_r:httpd_user_content_t

The file context entry specifies that directories in user home directories named public_html/ should be labeled user_u:object_r:httpd_user_content_t.

We can also use the restorecon command to check whether the labels on file-related objects match the specification in the file contexts files. For example:

$ mkdir public_html
$ /sbin/restorecon -nv public_html/
/sbin/restorecon reset /home/joe/public_html context
joe:object_r:user_home_dir_t->user_u:object_r:httpd_user_content_t

history command

Làm chủ command history trên Linux

Posted by dongthao on August 18, 2008 http://kythuatmaytinh.wordpress.com

Khi bạn thường xuyên sử dụng dòng lệnh trên Linux, kĩ năng dùng history hiệu quả sẽ giúp bạn tăng hiệu suất công việc lên rất nhiều. 15 ví dụ sau đây giúp bạn thấy sử dụng dòng lệnh thú vị và hiệu quả như thế nào.

1. Hiển thị thời điểm với HISTTIMEFORMAT

Thông thường khi bạn gõ “history” vào dòng lệnh, nó sẽ hiển thị số thứ tự và lệnh đó, chẳng hạn:

t3318@honey:~$ history
2 ./configure
3 sudo apt-get install gettext
4 ./configure
5 gmcs
6 sudo apt-get install mono-gmcs
7 ./configure
8 make
9 make install

Để theo dõi hiệu quả hơn, ta có thể hiển thị thời điểm kèm theo như ví dụ sau đây:

t3318@honey:~$ export HISTTIMEFORMAT=’%F %T’

t3318@honey:~$ history | more

5 2008-08-18 13:04:06gmcs

6 2008-08-18 13:04:06sudo apt-get install mono-gmcs

7 2008-08-18 13:04:06./configure

8 2008-08-18 13:04:06make

9 2008-08-18 13:04:06make install

10 2008-08-18 13:04:06sudo make install

2. Tìm kiếm trên history bằng Control+R

Chắc chắn chức năng này sẽ rất hữu ích. Khi bạn vừa thực hiện xong một lệnh rất dài, bạn có thể tìm kiếm trong history một cách đơn giản bằng một từ khoá và thực hiện lại y chang lệnh đó mà không cần phải gõ lại từ đầu. Hãy nhấn Control+R and type the keyword.

Trong ví dụ sau, tôi giả sử muốn tìm lại URL của một đoạn video youtube đã lấy về bằng youtube-dl. Tôi tìm chữ “you”, và kết quả như sau:

# [Nhấn Ctrl+R từ dấu nhắc lệnh sẽ hiện ra như sau]

(reverse-i-search)`you’: youtube-dl -g “http://www.youtube.com/watch?v=YuppZpVNpiA”

[Nhấn Enter khi bạn thấy lệnh mình muốn xuất hiện và nó sẽ được thực hiện]

t3318@honey:~$ youtube-dl -g “http://www.youtube.com/watch?v=YuppZpVNpiA”

http://lax-v195.lax.youtube.com/get_video?video_id=

YuppZpVNpiA&signature=B740C32BDF978EE6AFE62344948C59

Đôi khi bạn lại muốn hiệu chỉnh một một lệnh từ history trước khi thực hiện nó. Bạn chỉ cần sử dụng phím mũi tên sang trái hoặc sang phải khi kết quả tìm kiếm xuất hiện để chỉnh sửa, sau đó nhấn Enter để thực thi lệnh.

3. Lặp lại lệnh trước đó một cách nhanh chóng theo 4 cách

Dùng mũi tên lên để tìm lệnh trước đó rồi nhấn enter để thực thi
Gõ !! rồi nhấn enter
Gõ !-1 rồi nhấn enter
Nhấn Control+P để hiển thị lệnh ngay trước đó rồi nhấn enter để thực thi (nhấn Control+P nhiều lần sẽ giống như dùng mũi tên lên)

4. Thực hiện một lệnh xác định từ history

Giả sử bạn muốn lặp lại lệnh số 10, hãy gõ !10 như ví dụ sau:

t3318@honey:~$ history | more

10 2008-08-18 13:04:06sudo make install

11 2008-08-18 13:04:06cd

12 2008-08-18 13:04:06cd .mozilla-thunderbird/q0d4500j.default/extensions/

13 2008-08-18 13:04:06ls

14 2008-08-18 13:04:06cd ..

15 2008-08-18 13:04:06ls

t3318@honey:~$ !12

cd .mozilla-thunderbird/q0d4500j.default/extensions/

t3318@honey:~/.mozilla-thunderbird/q0d4500j.default/extensions$

5. Thực thi lệnh trước đó bắt đầu với một chữ xác định

Gõ ! tiếp theo là vài chữ bắt đầu của lệnh mà bạn muốn thực hiện lại.

t3318@honey:~$ !y

youtube-dl -g “http://www.youtube.com/watch?v=YuppZpVNpiA”

http://lax-v195.lax.youtube.com/get_video?video_id=YuppZpVNpiA&signa…

6. Thiết lập tổng số lệnh lưu trong history bằng HISTSIZE

Thêm hai dòng sau vào file .bash_profile sau đó đăng nhập lại vào shell để thay đổi có hiệu lực. Ví dụ ta muốn history chứa 450 lệnh

HISTSIZE=450
HISTFILESIZE=450

7. Đổi tên file history bằng HISTFILE

Mặc định, history được lưu trong file /.bash_history. Hãy thêm dòng sau vào file .bash_profile và đăng nhập lại shell, để lưu các lệnh trong history vào file .commandline_store thay vì .bash_history. Nếu bạn chưa biết thủ thuật này dùng để làm gì, thì theo dõi các lệnh thực thi trên nhiều terminal khác nhau bằng nhiều file history khác nhau là một trường hợp ví dụ.

HISTFILE=/root/.commandline_warrior

8. Loại bỏ các dòng trùng nhau liên tiếp trong history bằng HISTCONTROL

Chạy lệnh sau trước khi dùng lệnh history:

t3318@honey:~$ export HISTCONTROL=ignoredups

9.Loại bỏ các dòng trùng nhau trong toàn bộ history bằng HISTCONTROL

Thao tác ignoredups ở trên chỉ loại bỏ các dòng trùng nhau khi chúng nằm liên tiếp. Để bỏ các dòng trùng trong toàn bộ history ta thiết lập như sau:

t3318@honey:~$ export HISTCONTROL=erasedups

10. Không cho history lưu lại 1 lệnh cụ thể bằng HISTCONTROL

Khi thực thi một lệnh, bạn có thể cho history bỏ qua lệnh đó bằng cách thiết lập HISTCONTROL ở chế độ ignorespace VÀ gõ một khoảng trắng phía trước lệnh đó

t3318@honey:~$ export HISTCONTROL=ignorespace
t3318@honey:~$ pwd
t3318@honey:~$ ls
t3318@honey:~$ rm -rf new.pls [có khoảng trắng trước rm]
t3318@honey:~$ history | tail -3
527 2008-08-18 14:37:12pwd
528 2008-08-18 14:37:37ls
529 2008-08-18 14:38:17history | tail -3

11. Xoá tất cả các history trước đó bằng tùy chọn -c

Sometime you may want to clear all the previous history, but want to keep the history moving forward.

t3318@honey:~$ history -c

t3318@honey:~$ history

31 2008-08-18 14:40:42history

12. Điền tham số thích hợp từ các lệnh trong history

Khi tìm kiếm trong history, bạn có thể muốn thực thi một lệnh khác nhưng dùng cùng các tham số như là một lệnh vừa tìm ra trong history.

Trong ví dụ sau, kí hiệu !!:$ theo sau vim sẽ lấy tham số của lệnh trước đó làm tham số cho lệnh hiện thời:

t3318@honey:~$ ls postfix-large-fs.patch
postfix-large-fs.patch
t3318@honey:~$ vim !!:$
vim postfix-large-fs.patch

Còn trong ví dụ này, kí hiệu !^ theo sau lệnh vim lấy tham số đầu tiên của lệnh trước đó (trường hợp có nhiều tham số) làm tham số cho lệnh hiện thời

t3318@honey:~$ ls postfix-large-fs.patch sources.list_hardy
postfix-large-fs.patch sources.list_hardy
t3318@honey:~$ vim !^
vim postfix-large-fs.patch

13. Điền một tham số cụ thể từ một lệnh cụ thể

Trong ví dụ sau, !cp:2 tìm kiếm những lệnh trong history bắt đầu bằng cp và lấy tham số thứ hai sau đó điền vào ls -l

t3318@honey:~$ cp sources.list_hardy /home/t3318/Documents/New/sources.list
t3318@honey:~$ ls -l !cp:2
ls -l /home/t3318/Documents/New/sources.list
-rw-r–r– 1 t3318 t3318 292 2008-08-18 15:02 /home/t3318/Documents/New/sources.list

Còn ở ví dụ sau, !cp:$ tìm những lệnh bắt đầu với cp và lấy tham số cuối cùng (cũng là tham số thứ 2 của lệnh cp ở trên)

t3318@honey:~$ ls -l !cp:$
ls -l /home/t3318/Documents/New/sources.list
-rw-r–r– 1 t3318 t3318 292 2008-08-18 15:02 /home/t3318/Documents/New/sources.list

14. Tắt history bằng HISTSIZE

Nếu bạn không muốn lưu lại bất kỳ lệnh gì, hãy thiết lập HISTSIZE bằng 0

t3318@honey:~$ export HISTSIZE=0
t3318@honey:~$ history
t3318@honey:~$

15. Loại bỏ những lệnh xác định ra khỏi history bằng HISTIGNORE

Đôi khi bạn không muốn bị nhiễu khi tìm history bởi quá nhiều lệnh “pwd” hay “ls”. Use HISTIGNORE để xác định tất cả các lệnh bạn muốn loại khỏi history. Lưu ý là thêm lệnh ls vào HISTIGNORE sẽ chỉ loại “ls”‘ chứ không phải “ls -l”. Bạn phải cung cấp lệnh đầy đủ cả tham số nếu cần.

t3318@honey:~$ export HISTIGNORE=”pwd:ls:ls -ltr:”

How to Install g++ on CentOS 4 and CentOS 5

19 Nov

Posted by: admin in: Linux Tricks

g++ is often necessary for building various packages. But It’s quite hard to install it in CentOS if you don’t know a simple thing: yum install g++ will not work here. yum install compat-g++and yum install gcc-g++ won’t give any result too. The only command for yum to install g++ on CentOS is the following:

yum install gcc-c++

You might also want to install it with some more useful packages. Then your command will be:

yum install gcc-c++ compat-gcc-32 compat-gcc-32-c++

Hope this helps you to install g++ under CentOS

Setup rsync server on CentOS

September 1, 2007, 10:13 pm

Posted by am3n in Linux

Step-by-step installation and configuration rsync server on CentOS
From transamrit.net

Make sure xinetd and rsync is available, if not type
# yum -y install rsync xinetd
Add xinetd service to system
# chkconfig --add xinetd
Make sure xinetd running on init 3 and 5
# chkconfig --list xinetd
Enable rsync
# vi /etc/xinetd.d/rsync
Change disable = yes into disable = no
Create username and password for rsync client to use
# vi /etc/rsyncd.secrets
adminname:hispassword
Create configuration and shares for rsync daemon
# vi /etc/rsyncd.conf
max connections = 2
log file = /var/log/rsync.log
timeout = 300

[shares]
comment = shared data stored here
path = /home/adminname/shares
read only = false # chg to true if you want read only
list = yes
uid = adminname
gid = adminname
auth users = adminname
secrets file = /etc/rsyncd.secrets
hosts allow = 10.10.105.0/24
Secure /etc/rsyncd.*
# chown root.root /etc/rsyncd.*
# chmod 600 /etc/rsyncd.*
Restart xinetd
# service xinetd restart
Make sure rsync now running
# chkconfig --list
Perhaps you also want to enable port 873 tcp and udp on your firewall so other can connect to your server

rsync over ssh

2008-12-02T13:50:00.002+07:00

rsync -avzr -e ssh root@src:/ dest

Option:
a = archive
z = compress
--exclude=".*/" # excluded hidden file or hidden directory
r = recursive directory
e = over ssh
vv verbose
--delete = xoa cac file co tren dest ma ko co tren src
-u, --update skip files that are newer on the receiver

SU Error - su: not running setuid If this error occures while you try to su, it means that you need to set SUID bit to su binary like below: $ su -

2008-11-13T15:26:00.000+07:00

SU Error - su: not running setuid

If this error occures while you try to su, it means that you need to set SUID bit to su binary like below:

$ su -
su: not running setuid

(BECOME ROOT SOMEHOW AND THEN...)

# ls -l `which su`
-r-xr-x--- 1 root wheel 14324 Apr 12 23:14 /usr/bin/su
# chmod u+s `which su`
# ls -l `which su`
-r-sr-x--- 1 root wheel - 14324 Apr 12 23:14 /usr/bin/su
# su - andrei
$ su -
Password:

So above commands do:

ls -l `which su` - lists su binary
chmod u+s `which su` - adds SUID bit to su binary
exactly like 1.
su to another user ( andrei in this case)
su to root from a normal user. See that the error does not occure any more.

notes: instead of `which su` you could use directly /path/to/su/binary if you know it, and you can use `which su` and it'll work on both Linux & FreeBSD.

This error occured after a buildworld. I suspect that because of file flags I use.

turn off smux port 199

2008-11-07T18:05:00.000+07:00

To turn off SMUX when you don't have the options of recompiling from source
to disable SMUX support, you have to give it an invalid IP address to bind
to. This may be OS specific. On Linux, if I put this in my snmpd.conf:

smuxsocket 1.0.0.0

I get an error at startup, and lsof or netstat show that snmpd is no longer
listenting on port 199. If you get and error message about the smuxsocket
token not being recognized, then you're out of luck. You'll have to recompile
from source (or just use local firewall rules to block connections to port
199).

Minimum password length + fedora

2008-10-21T16:46:00.001+07:00

Hello,
I have a Fedora Core 2 system and I'm trying to adjust the system's
minimum password length to be less than 6. I edited the
/etc/login.defs file to look like

# PASS_MAX_DAYS Maximum number of days a password may be used.
# PASS_MIN_DAYS Minimum number of days allowed between
password changes.
# PASS_MIN_LEN Minimum acceptable password length.
# PASS_WARN_AGE Number of days warning given before a password
expires.
#
PASS_MAX_DAYS 99999
PASS_MIN_DAYS 0
PASS_MIN_LEN 0
PASS_WARN_AGE 7

and restarted the machine. But when I try and change my password with
the "passwd" command to a password of 5 characters, I get the message
"Password is too short." What other file must I alter? How can I
change the default minimum password length?

Thanks, - Dave

How to use VNC server on CentOS

2008-10-14T10:55:00.000+07:00

How to use VNC server on CentOS

Assume you have CentOS installed with Gnome. If you want to remotely access the GUI to that machine, you can use vnc-server and a vnc client (like Chicken of the VNC). Here's how:

ssh to the machine. If it is behind a firewall, you might have to set up a tunnel.
Make sure vnc-server is installed:

% sudo yum install vnc-server

Run vnc-server:

% vnc-server

This is just to initially create configs and choose a password. Now Edit the file ~/.vnc/xstartup so it runs a gnome session instead of crappy twm:

#!/bin/sh

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
exec gnome-session &

Kill off your vnc server and restart it:

% killall Xvnc
% vnc-server

Connect to your vnc server with host and display number reported with your favorite client. Yay.

How To: Allocating more memory for Java and Tomcat

2008-09-10T09:41:00.000+07:00

How To: Allocating more memory for Java and Tomcat

Summary

To avoid java.lang.OutOfMemory errors, increase the value of -Xmx512M

Issue
I 'm getting java.lang.OutOfMemory errors

Applies to
Adobe Graphics Server
Adobe Document Server

Solution
The problem is that by default, the Java Virtual Machine and Tomcat (WebServices) only use a small amount of memory. You can adjust the RAM they will use with the -Xmx option as in -Xmx1000M. (Meaning use up to 1000MB if available.)

When using the WebServices from the Java command line, you must use the -Xmx option twice. Once to increase the RAM available to Tomcat (WebServices), and second for the Java command line.

Determining how much RAM is needed
If you're working with images that are roughly 4000 x 4000 pixels and one layer, try -Xmx1000M as a starting point.

Run your commands against your largest file and watch the memory usage of the Java processes.
On Windows: use the "Processes" tab of the "Windows Task Manager"
On Solaris: run "prstat" in a Console window
Adjust the value of -Xmx based on the RAM requirements of your commands and your files. (convertProfile and saveOptimized use more RAM than some of the other commands.)

Assign more RAM to the Java command line examples
1. Open, for example, ResizeImage.bat or ResizeImage.sh at:
{your install location}\Samples\java\commandline\ResizeImage.bat

2. Add -Xmx1000M to the line:
set COMMAND=java -cp "%THECLASSPATH%" com.adobe.altercast.commandline.ResizeImage %*
resulting in:
set COMMAND=java -Xmx1000M -cp "%THECLASSPATH%" com.adobe.altercast.commandline.ResizeImage %*

Assign more RAM to Tomcat (WebServices) on Windows

Open wrapper.properties at:
{your install location}\server\conf\wrapper.properties
Scroll down to the bottom and you will find:
# This is the command line that is used to start Tomcat. You can *add* extra # parameters to it but you can not remove anything. # wrapper.cmd_line="$(wrapper.javabin)" -Xrs-Xmx512M -classpath "$(wrapper.class_path)" $(wrapper.startup_class) -config "$(wrapper.server_xml)" -home "$(AlterCastTomcatHome)"
Modify the value of: -Xmx512M
Restart the AlterCastDocEdition service or the AlterCastImageEdition service in the Services control panel.

Assign more RAM to Tomcat (WebServices) on Solaris

Open in a text editor tomcat.sh at {your install location}/server/bin/tomcat.sh
Find the line reading: TOMCAT_OPTS=" -Xmx512M" and modify whatever number is currently there
Restart Tomcat using:
shutdown.sh and then startup.sh

The Tomcat environment for FreeBSD

2008-09-10T08:55:00.001+07:00

3.2 The Tomcat environment for FreeBSD

It is very simple to install Tomcat on a FreeBSD machine, after setting up the necessary Java environment, which we have previously completed.

In-order to set up Tomcat on FreeBSD, follow the below procedure:

Follow the above steps to set up the necessary Java environment.
Set an environment variable JAVA_HOME which, points to the directory where you have installed the JDK (the examples below point to a native build of the JDK). If you are using sh(1) as your shell, you can set JAVA_HOME with:
```
# export JAVA_HOME="/usr/local/jdk1.3.1"
```
Those who use csh(1) or a compatible shell, must use a slightly different command:
```
# setenv JAVA_HOME /usr/local/jdk1.3.1
```
This environment variable should be made permanent by adding it into either .profile or .cshrc, depending on the shell you are using. This variable is very crucial for the functioning of all the Java based programs, including Tomcat itself.
Download the Tomcat “binary distribution” from the Jakarta website, which is located at http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0.6/bin/. The file to download is called jakarta-tomcat-4.0.6.tar.gz.
The compressed and archived file we downloaded in the previous step uses special “GNU Extensions”. In-order to untar and uncompress the file, we will need to install GNU Tar (archivers/gtar), by doing the following:
```
# cd /usr/ports/archivers/gtar && make all install clean
```
Un-tar and Un-compress the jakarta-tomcat-4.0.6.tar.gz file into the /usr/local directory and rename the directory to tomcat-4.0 for ease of reference:
```
# cd /usr/local
# gtar zxvf jakarta-tomcat-4.0.6.tar.gz
# ls jakarta*
jakarta-tomcat-4.0.6
# mv jakarta-tomcat-4.0.6 tomcat-4.0
```
You can remove the jakarta-tomcat-4.0.6.tar.gz at your preference.

Note: Installation by using the source code is currently out of scope for this document. Please refer to the following files for addition information on building from source, available from your Tomcat distribution directory:

“With its rock-solid foundation and ground-breaking new features, Windows XP Professional won’t quit working, even when your workday is done.” — Microsoft
(Did they know what they were saying?)

Shutdown problems in Windows XP can be caused by many factors, just like earlier versions of Windows. These included: a damaged exit sound file; incorrectly configured, damaged, or incompatible hardware; conflicting programs, or an incompatible, damaged, or conflicting device driver.

For a step-by-step troubleshooting method that applies to all versions of Windows 9x, see the generic Windows Shutdown Troubleshooter. Some of its steps may be found to apply to Windows XP as well, though many will not.

Windows XP shutdown issues mostly center around a very few issues, especially legacy hardware and software compatibility issues.

Currently, the leading cause of Windows XP shutdown problems is hardware incompatibility, including driver issues. These are detailed below where known. However, it is impossible to list every possible hardware or driver issue individually. My best advice is: Check all drivers for all hardware devices to ensure that they are the current best for Windows XP.

REBOOT INSTEAD OF SHUTDOWN

Most Win XP shutdown problems reported thus far have been that it reboots when shutdown is attempted. This may be a global symptom emerging from several distinct causes, because, by default, XP executes an automatic restart in the event of a system failure. Therefore, more or less anything compromising the operating system during the shutdown process could force this reboot.

Disabling the “restart on system failure” feature may permit the exact cause to be isolated: Right-click on My Computer, click Properties, click the Advanced tab. Under “Startup & Recovery,” click Settings. Under “System Failure,” uncheck the box in front of “Automatically restart.”

Here are some things that have produced this reboot-instead-of-shutdown symptom:

By now, the Roxio/Adeptec Easy CD / Direct CD software is well documented as being the major cause of this undesirable shutdown behavior. SOLUTION: Roxio has released new drivers (here) to solve this problem in both the Platinum and Basic editions of Easy CD Creator 5. As expected, at least half of the Win XP shutdown problems went away with the release of these patches.

One warning about this patch comes from correspondent Bert Smith: Be sure to read the directions! “Roxio Easy CD Creator Platinum 5.0 can be a real hassle to get working under Win XP,” Bert wrote, “and there is the risk of your computer not booting if you blindly go ahead and install it without first consulting the Roxio Web site.” Bert also mentioned that Roxio’s “Take Two” backup program (normally part of Easy CD Creator 5 Platinum) is uninstalled when the Roxio patch is applied.
- Direct CD. Many Easy CD users (but not all) found that installing Easy CD 5.0 does not cause the shutdown problem, provided they do not install the Direct CD component.
- UDFRINST. Several people solved this reboot-on-shutdown problem by deleting the UDFRINST file. This file is part of the Roxio CD-RW software for systems not using Direct CD.
- CDRALW2K.SYS. Correspondent Larry Blumette identified the CDRALW2K.SYS file (version 1.0.0.1048) as the Roxio file causing his shutdown problems and error conditions. When he deleted or renamed this one file, his problems went away. (Of course, you lose your CD functionality that way, too.)
- Video Pack 5. Roxio’s Video Pack 5 causes the same problem because it contains includes the main parts of Easy CD 5. SOLUTION: Uninstall Video Pack 5 and also delete CDRALW2K.SYS (Tip from Christian Männchen). However, this solution may also have the side-effect of disabling access to your CD or DVD drive. SOLUTION TO THE SIDE-EFFECT: Apply one of the repair methods in MSKB Article 270008, Code 31 Messages Occur After Removing Adaptec Easy CD Creator 4.02c in Windows 2000 (Tip from Peter Kingsley).
Whether or not APM is enabled makes a difference — but the effect could go two ways. Some users report that XP reboots on shutdown if APM is enabled, but shuts Windows down just fine if APM is disabled. Other users report exactly the opposite behavior. According to Jack Dunne, this is similar to a known Windows 2000 problem. The issue seems related to the computer’s specific hardware or BIOS — so, as with all NT operating systems, stick to the Hardware Compatibility List where possible.
USB Connections As can be seen from remarks in the Misc. Hardware Issues section below, several different USB-related issues can impact shutdown. One of the most concrete examples was a “reboot on shutdown” problem contributed by correspondent Rick Bross. If his several USB devices (PDA cradle, flash card reader, etc) were plugged into the motherboard’s USB ports, his computer would reboot on an attempted shutdown; but when, instead, he plugged them into an external USB 2.0 hub, shutdown went just fine. (This was with Win XP Professional SP1 on a Supermicro X5DAE dual Xeon motherboard. The same devices plugged into an Asus A7M-266D dual AMD 2000MP system on the same OS worked without problem.)
“Wake on” power settings Power-management settings that have the computer “wake” on LAN, USB, modem, or (for that matter) probably anything else may also trigger a restart after shutdown. Correspondent Simon Wei provided this tip after a friend of his found an old old Logitech USB mouse would trigger “wake on USB” after every Windows shutdown. Their solution was to remove that particular mouse and all worked fine. The principle is much more far-reaching than this one example.
Hidden “wake on” power settings If you have an Ethernet card integrated into your motherboard, you may have hidden “wake on” settings that are harder to find. Site visitor Jim Porter found that his Asus P5GDC-V Deluxe motherboard had a “wake on” setting in Device Manager | Properties | Advanced rather than in the BIOS or Power Management settings. (The Asus P5AD2 and P5GD2 boards have this also.)
Y-SB3 Logitech Internet Keyboard can also cause this problem. If you use it as a simple generic keyboard, there’s no problem; but, if you install the Key Commander software that drives the special Internet functions, Win XP will restart instead of shut down. Unfortunately, Logitech has decided that they will not be updating this driver for this keyboard. (Tip from Jan K. Haak.)
Logitech MouseWare 8.6. Windows reboots when shutdown is attempted. The software caused a BSOD with KBDCLASS.SYS. Removing the software solved the BSOD the problem. (Tip from Pablo Cheng.) MouseWare 9.0 and 9.1 also have been linked to reboot-instead-of-shutdown in Win XP. Removing the software resolves the problem. (Tip from Aswin Kindts, Greg Williams, and others)
Webstar DPX USB cable modem. In the one case known to me, the problem was solved by switching the modem’s connector from the USB 1.1 port on the motherboard to the USB 2.0 PCI card. (The modem was provided by Telewest Broadband, manufactured by Scientific Atlanta.) (Tip from Ann L. Goonan.)

SHUTDOWN HANGS ON “SAVING YOUR SETTINGS”

During shutdown or reboot, Win XP may hang (stop responding) at the “saving your settings” screen. During such a hang, there is no response to Ctrl+Alt+Del; the mouse may or may not work. The problem may be intermittent.

This is a known bug in Windows XP, for which Microsoft has a supported fix. To learn how to get this patch, see MSKB 307274, “Windows XP Stops Responding (Hangs) During Windows Shutdown.” The necessary patch is included in Windows XP Service Pack 1, and also is now available on the Windows Update site under “Recommended Updates” for Win XP Professional, titled “Restarting Windows XP.” However, to find it, you may need to reconfigure how Windows Update appears for you, by enabling the Windows Update Catalog as follows: At the Windows Update page, click Personalize Windows Update at the left, and then Enable the Windows Update Catalog. Save your settings. This adds the Windows Update Catalog link in the left box. Click this link, then click Find updates for Microsoft Windows systems. Pick Windows XP in the drop-down list, click Search, take Recommended Updates, and find the “Restarting Windows XP” patch which references Q307274.

As a workaround, newsgroup correspondent “lou” resolved this problem by dismantling the Windows XP logon Welcome screen. In the Control Panel, click User Accounts, then click “Change the way users log on or off.” Uncheck the box that says “Use the Welcome screen.” This removes the initial logon screen with individual icons for each user and, instead, pops up the classic logon prompt that requires each user to type a user name and password.

SBLive: DEVLDR32.EXE PROBLEMS

In the early days of Win ME, one of the biggest culprits for shutdown issue was the Creative Labs SoundBlaster Live. History repeated itself in the Beta phase of Win XP. SOLUTION: The SBLive drivers in the released version of Win XP solved the shutdown problem for most (but not all) SBLive users.

Here’s the commonly reported problem scenario people encountered: On attempting shutdown, nothing at all appears to happen for a prolonged period of time. Eventually, an “End Task” window appears, wanting to terminate DEVLDR32.EXE. No matter what one does, one ultimately is locked out of shutting down other than by a power switch shutoff. (NOTE: This problem exists with the SBLive in Windows 2000 also.)

You may have to do a couple of extra steps to get rid of old files so that the new drivers will install correctly (especially if you installed the final version of Win XP on top of one of the Beta versions), or to remove troublesome support software. Correspondent Sean Caldwell summarized his steps: Shutdown Windows. Remove the Creative card. Reboot in Safe Mode. In the \WINDOWS\SYSTEM32 folder, delete the DEVLDR file. Fully shutdown the computer before rebooting.

Some users report that the DEVLDR problem continues to plague them even with the new drivers. If installing the new drivers doesn’t solve your shutdown problem, try these solutions:

Correspondent Martin Sladek wrote: “I’ve run into the very same problem with SBLive Value drivers. The problem was so severe I ran without the software all together. Since then, SBLive 5.1 came out, and I had installed the 5.1 version of the software in Windows 2000 Pro. I’ve not had a single problem since.”
But updating your drivers in Win XP may not be as easy as one would hope. Some problems especially appear where multiple users are enabled on the system and one switches between users during a single Windows session. There may be numerous files with the same name (but different version numbers!) variously located in the I386, SYSTEM32, and SYSTEM32\REINSTALLBACKUPS\0000 folders. These may conflict with each other. If you rename DEVLDR32 (ver 1.0.0.22) in SYSTEM32, another one will replace it. (First, you need to press Ctrl+Alt+Del and end DEVLDR in Task Manager). But if you use DEVLDR32 (ver 1.0.0.17) from the I386 folder, this problem doesn’t occur. Reboot when finished to reinaugurate the disabled service. (Tip from Terence Shortt, aka tbone8200 on dellTalk.)

MISC. HARDWARE ISSUES

In addition to hardware issues mentioned under other specialized topics on this page, many users have written identifying specific hardware as at the root of the Windows XP shutdown issue. Here’s what they have reported:

CD-ROM DRIVE: Samsung 24x. Correspondent Y. Leroux has identified the culprit in his shutdown problem, but doesn’t yet have a permanent solution. If his Samsung CD-ROM drive is empty, Win XP hangs on shutdown. To work around the problem, he either leaves a CD-ROM in the drive, or leaves the drive door open. He wanted to share this tip with others (thanks, Y.). Does anyone have a permanent solution for this one?
DVD-RW DRIVE: Pioneer DVR-106 or DVR-108. Correspondent L. Frankenberg traced his shutdown problem to this hardware. Correspondent Bob Berberick found the same for the DVR-108, and reported that a firmware update for the DVR-108 now available from Pioneer resolved his problem. It would probably be worth trying the firmware update for the DVR-106 as well, though I have no reports from anyone as to whether this solves the shutdown problem.
MODEMS: Intel Ambient HaM Modem. Causes Win XP to hang at shutdown. Previously, this was only resolved by disabling the modem. SOLUTION: Intel subsequently issued updated drivers that resolve this issue. They can be downloaded here. (Tip from Mark Gillespie.) However, a new problem with the Ambient Ham was introduced in Windows XP SP1, detailed below.

NOTE: The same problem has been reported for the Creatix V.90 Ham PCI Modem. Correspondent Gert Verheyen wrote that Creatix has an updated driver and, more importantly, detailed instructions about manual removal of the old one and installation of the new one. Go to the Creatix support page and click on V.90 HAM (internal) at right. The removal of the old driver first seems to have been the critical detail.
MODEMS: Billion BIPAC PCI Passive ISDN-card. Reboot instead of shutdown issue conjoined with BSOD error message STOP 0x000000D1: DRIVER_IRQL_NOT_LESS_OR_EQUAL in file SERIAL.SYS. Previously, this was only resolved by disabling the Billion ISDN card. SOLUTION: Billion has now released a new driver 3.24 that solves this problem, available here. (Tip from Leo Foederer.)
MOTHERBOARDS: Asus P2B-F, P2B-VM, or P2L97. Causes a shutdown problem because Win XP Setup doesn’t enable ACPI by default. SOLUTION: Manually enable ACPI during a Win XP install or reinstall. Correspondent Bill Anderson (based on a solution by “Willy”) gave a lengthy description of how to do this, edited a little for space reasons. (Thanks also to correspondents Ward from Belgium & Tony Gray.)
1. Boot the computer from the Win XP CD-ROM.
2. Win XP Setup says it’s checking hardware. Soon after, at the bottom of the screen, it offers the opportunity to press F5. (If offered the chance to press F6, press F5 instead! – Tip from Mick Stone) Do this at once, and cross your fingers! [Various users report difficulty with this. Apparently, sometimes it works; sometimes not. It may be in the timing of exactly when you press the key. You may have to try repeatedly, or try pressing F5 and F6 repeatedly. – JAE] When successful, you’ll see a two-paragraph instruction that begins, “To specify additional SCSI or other mass storage devices.” Press to brings up a small window that appears to contain only two options, but, in fact, contains more (use the arrow keys to scroll up). If this windows doesn’t appear at this point, you need to start over and do more pressing of F5!
3. When the small window does appear, use the up-arrow to choose “Advanced Configuration and Power Interface (ACPI).” (It’s the third from the top of the list.)
4. Next, you may see that two-paragraph SCSI/mass storage instruction again. If so, press . Many drivers will load, then you should see the Win XP installation screen. If you are running this after Win XP is already installed, choose the Repair option.
MOUSE: Logitech. If you have a Logitech mouse, and an outdated version of the MouseWare software installed, you may receive the following error message on a blue screen at shutdown: STOP 0x000000D1, (0x0000002b, 0x00000002, 0x00000000, 0xEEEE1b01) IRQL_NOT_LESS_OR_EQUAL Kbdclass.sys. SOLUTION: Update the Logitech MouseWare software. (Reference & more information: MSKB 810980.)
VIDEO CARDS: Hercules 3D Prophet 4500 and all other video cards based on the Kyro II video chip. Causes restart and shutdown issues (or, in some cases, only restart issues) until the video adapter is removed. SOLUTION: New XP-specific drivers are now available from Hercules. At present, they remain uncertified (PowerVR, who makes the Kyro II chip, is working on that), but they reportedly work just fine. Download the Kyro II drivers here. (Tip from MS-MVP Don Lebow.)
USB Devices. If you have one or more USB devices attached to your computer, you may receive the following error message on a blue screen at shutdown: Stop 0x000000D1 (0x00000040, 0x00000002, 0x00000000, 0xfc96a9dc). SOLUTION: Upgrade to the latest Win XP service pack. (Reference & more information: MSKB 317326.)
USB: Keyboard or Mouse + Selective Suspend. Some USB input devices (such as a USB keyboard or mouse) do not support the Selective Suspend power management feature. When these devices are used with Selective Suspend turned on, the computer may hang during shutdown, or otherwise not shutdown correctly. WORK-AROUND: Disable power management for your USB hub: Open Device Manager (click Start, click Run, type DEVMGMT.MSC, click OK). Double-click to expand Universal Serial Bus Controllers. Double-click USB Root Hub. Click Power Management. Uncheck the box “Allow the computer to turn off this device to save power.” OK your way out. NOTE: Doing this may significantly reduce laptop battery life. (Reference & more information: MSKB 315664.)
USB: Lexar Media Combo Digital Film Reader (USB). There is a problem with the SAUSB.SYS file, apparently part of the Win98 SE driver set for this device, retained during an upgrade to Win XP. Deleting the file solved the problem. The newer version 4.3 SAUSB.SYS driver from Lexar’s Web site works perfectly, and does not cause a shutdown problem. (Tip from correspondent Eric Brown.) Though one correspondent reported that the even newer version 4.5 driver (SAUSBI.SYS) also can be used in Win XP , Lexar says this driver doesn’t work on XP. One correspondent has confirmed that this matches his experience in trying (unsuccessfully) to use 4.5 on both Widows 2000 and XP.

“STOP” ERROR MESSAGES AT SHUTDOWN

Some users, when attempting either to shutdown or restart Win XP, get an error message similar to the following: STOP 0x0000009F: DRIVER_POWER_STATE_FAILURE

Stop Messages literally means that Windows has stopped. (Which isn’t the same as saying it has shutdown!) See Knowledge Base Links: STOP MESSAGES for much more information that the brief remarks below. Most Stop Messages indicate hardware issues; some are caused by troublesome software or a system service problem. The links page just mentioned provides a 10-step approach to troubleshooting STOP Messages in general, then itemized analysis on the most common of these. (STOP messages are identified by an 8-digit hexadecimal number, but also commonly written in a shorthand notation; e.g., a STOP 0x0000000A may also be written Stop 0xA.)

Here are a few that may affect Win XP shutdown and restart. Stop 0x9F and Stop 0x8E are two of the most common of these at shutdown, and generally point to a bad driver. Stop 0x7B on restarting means Win XP lost access to the system partition or boot volume during the startup process, due to a bad device driver, boot sector virus, resource conflict, boot volume corruption, or other problem listed here. Stop 0xC000021A can when on restart after a system administrator has modified permissions so that the SYSTEM account no longer has adequate permissions to access system files and folders.

MS-MVP Jim Pickering advises the following as one approach to these problems: Restart the computer. Press F8 during the restart and select “ Last Known Good Configuration.” If you catch the problem when it first occurs (meaning you likely have installed only one or two drivers or new service), this will return you to a previous working condition. System Restore provides an alternate approach, especially if you need to go back further than the last known good configuration, and Device Manager provides a tool for rolling back to an earlier driver.

SHUTDOWN WORKS, BUT IT’S REAL SLOW

If it appears that Win XP is not shutting down, give it some time. Some users report a minute or longer for shutdown to visibly start. Generally, this is a consequence of software that is running when shutdown is attempted. It also may have something to do with particular hardware. If you experience this problem, be sure to close all running programs before attempting shutdown and see if this solves your problem. If so, then you can determine, by trial and error, which program(s) are involved.

Newsgroup correspondent “Sarah” provided one specific solution for this. In Control Panel | Administrative Tools | Services, stop the Nvidia Driver Helper service. (You can also get this by launching SERVICES.MSC from a Run box.) Many other newsgroup participants quickly confirmed that this solved this “extremely slow shutdown” problem for them (it’s the most successful solution for this problem to date). According to correspondent Gan Ming Teik, downloading and installing the new version 23.11 Nvidia driver also solves this problem.

Correspondent Ron Spruell found that disabling the Terminal Services service reduced his shutdown time from over 2 minutes (hanging at the “Windows is shutting down” screen) to about 10 seconds. To disable Terminal Services, follow the steps in the prior paragraph for launching SERVICES.MSC. Please note that Terminal Services is required in Windows XP for running Remote Assistance, Fast User Switching, and (in XP Pro) Remote Desktop.

Correspondent Graeme J.W. Smith reported a more obscure cause of slow shutdown: In Win XP Professional, the Group Policy Editor has a security option to clear the pagefile at system shutdown. The same setting also forces the hibernation file to be wiped at shutdown. These processes take long enough that users may think that shutdown has hung. To change the setting, click Start | Run, type GPEDIT.MSC, click OK. Drill down to Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options. In the right pane, find “Shutdown: Clear virtual memory pagefile.” NOTE: Since someone actually has to have set this policy, the problem will be pretty rare, but is worth mentioning. However, Forum participant “roadrunner” reported that the personal security app Privacy Eraser automatically enables “Clear virtual memory pagefile,” and, therefore, may be the cause of a slow shutdown.

The Gear Software Security Service (GEARSEC.EXE), which enables iTunes for Windows to read and burn CDs, has been reported by many users to cause Windows XP to hang at the “Windows is shutting down” screen for as long as 20-30 seconds. WORK-AROUND: Stop the service prior to shutdown. One way to to this (suggested by “Thornburgh”) is to create a batch file with the one line net stop gearsecurity. You can either launch this batch file manually, or (in Win XP Professional) use GPEDIT.MSC) to specify this batch file as the shutdown script (under Computer Configuration | Windows Settings | Scripts | Shutdown). Gear Software’s forum has a thread on this issue here. (Tip from correspondent “Andy”)

MS-MVP Gary Thorn discovered that the Event Log can slow down Win XP shutdown. Disabling event logging removed the slowdown. If this works for you, then the real troubleshooting begins: finding out, by trial and error, what item that is being logged is causing the actual slowdown. (In Gary’s case, the Telephony service was causing the problem.) To disable the Event Log, launch the Services console as detailed in No. 2 above, and disable Event Log (right-click on Event Log, click Properties, under Startup Type select “Disabled”).

In a domain environment, don’t forget to check any logoff scripts you are pushing. These can be a source of slow or hanging shutdown processes. Site visitor Tony Barkdull, for example, found that an enforced logoff script caused show shutdown for laptops that were off-site. He solved it be creating a logoff script on the local machines that deletes the Active Directory logoff group policy after it runs so that the logoff scripts are absent while a user is off-site, but are repopulated when they return. — A related cause of slow shutdowns is offline synchronization of data, which is increasingly common with mobile computing, but is usually much more obvious to the end-user.

POWERDOWN ISSUES

“Powerdown issues” are quite distinctive from “shutdown issues.” I define a shutdown problem as one wherein Windows doesn’t make it at least to the “OK to shut off your computer” screen. If Windows gets that far, or farther, then it has shut down correctly. However, the computer may not powerdown correctly after that. This is a different problem, and I encourage people reporting these issues to make a clear distinction in their labeling.

When Windows XP won’t powerdown automatically, the APM/NT Legacy Power Node may not be enabled. To enable this, right-click on the My Computer icon, click Properties | Hardware | Device Manager | View. Check the box labeled “Show Hidden Devices.” If it’s available on your computer, there will be a red X on the APM/NT Legacy Node. Try enabling it and see if this resolves the powerdown problem (Tip from Terri Stratton). Or, to check the other side of the APM/ACPI coin, open the Power Options applet in Control Panel. If there is an APM tab, make sure the “Enable Advanced Power Management Support” box is checked. (MSKB 313290)

This should resolve the powerdown issue in most cases. However, other factors can sometimes interfere with correct powerdown functioning. In that case, consider the following tips:

Try some of the solutions on my Shutdown & Restart Shortcuts page. If you really have a hardware inability to powerdown, these won’t solve it; but for some other underlying causes of powerdown failures, they just might.
If you change the default power settings in the BIOS, it can lead to a powerdown problem. Restoring all BIOS power settings to default will likely fix it. (Tip from Kelly Theriot)
Sometimes, not all appropriate Registry settings are made when you enable all the right power management settings in Windows. You can force the critical Registry setting with the “ShutNTdown” Registry patch. Please follow sensible Registry editing protocol. Backup your Registry before the change (or run System Restore to create a restore point). After installing it, test Windows shutdown. If the fix doesn’t work for you, remove it by restoring the Registry to its prior state. (For those who want more background information, the fix provided by this patch is based on information contained in MS Knowledge Base article 155117 for Windows NT 4.0.)
On some hardware, power management features simply don’t work right. This is exceedingly rare on Windows XP when compared to any earlier version of Windows but, on some machines, especially if no BIOS upgrade is available, there seems no conclusion to reach except, “Yes, you’re right, it doesn’t work, so don’t use that feature.” Accordingly, several correspondents have noted that their Win XP computers will not powerdown correctly unless they have Turn Off Monitor, Turn Off Hard Disks, and System Standby all set to “Never” in Control Panel | Power Options. (Tip from Dan Mitchell & others)
How old is your power supply? Correspondent Andrew Walsh had a computer that wouldn’t power down after a Win XP shutdown until he replaced the power supply that was a few years old. Presto! His problem was gone.
Correspondent “Snake” restored powerdown functioning by disabling his CD-ROM’s AutoRun feature. The fastest way to do this is with the “Disable AutoRun” Registry patch that you can download here.
If you have Office XP installed, the culprit may be CTFMON.EXE. This module provides the Alternate Language Bar and provides text input service support for speech recognition, handwriting recognition, keyboard, translation, and other alternative user input technologies. When you close all Office programs, this module stays active. Removing it can cause serious problems with your Office XP products, but you can effectively disable it by setting the installation state to Not Available in Office XP Setup. This isn’t as easy as it sounds though — several steps are involved. For full instructions, plus more information on the file and its function, see What Is CTFMON and What Does It Do? (Tip from Jay Jones)
VIA Apollo Pro 133 motherboards have a “USB Keyboard support” BIOS setting that can interfere with proper power management function if it is enabled — especially with respect to preventing powerdown during attempted shutdown, and also preventing the computer from waking from Stand-by. SOLUTION: Disable it. This was originally reported on the Chaintech 6ATA2, and confirmed on other VIA Apollo Pro 133 boards. (Tips from “Zef,” The Netherlands, & Robert Lin)
Toshiba laptop (model not specified). Problems of Windows XP not powering off nor going into standyby were solved by uninstalling (then reinstalling) the Toshiba Power Saver software and Toshiba Hotkey for Display Devices. After doing this and a reboot, the problem was gone. (Tip from David Flitterman)

NEW PROBLEMS INTRODUCED BY SERVICE PACK 1 (SP1)

Some new shutdown and powerdown issues have arisen in Windows XP SP1. Here are the ones I know about:

HIBERNATION/STANDY PROBLEM WITH NERO SOFTWARE. If you have Nero CD-burning software (versions 5.0-5.5) installed on your computer, and invoke Standby or Hibernation modes more than once in a Windows session, the computer will hang on the “Preparing to...” screen and not go into Standby or Hibernation. SOLUTION: Uninstall Nero completely, and keep your eyes open for a new version of the program down the road. (Reference: MSKB 331506.)
WITH SP1, DON’T REMOVE SCSI ADAPTER WHILE IN STANDBY. Service Pack 1 for Windows XP introduced a new (but pleasingly rare) shutdown problem: If you remove certain kinds of SCSI adapter while the computer is in Standby, the computer may not shut down properly. There is a “hot fix” for this available from Microsoft. (Reference: MSKB 330172.)
SP1 + AMBIENT HAM MODEM + POSSIBLE IRQ ISSUE. Site visitor Mike Redman wrote that, after installing SP1, his computer would hang on the shutdown screen. Neither the mouse nor Ctrl+Alt+Del would respond. Either uninstalling SP1 or removing his Intel Ambient Ham 50.sys (unsigned driver) internal modem would solve the problem. FINAL SOLUTION: Moving the modem from PCI slot 4 to slot 5 and reinstalling the drivers. He wrote, ”This may be an IRQ problem which SP1 was supposed to fix.”

NEW PROBLEMS INTRODUCED BY SERVICE PACK 2 (SP2)

Some new issues have arisen in Windows XP SP2. Here are the ones I know about:

AUTOMATIC WINDOWS UPDATE INSTALLATION. Windows XP SP2 checks at shutdown for any Windows Updates have been downloaded and not installed, then offers to install them as part of the shutdown process. Understandably, this can cause a very slow shutdown on that one occassion and, if something goes wrong, can even hang shutdown completely. To see if your shutdown problem is caused by this issue, look for error 0x80248011 in any of the Windows Update log files, particularly %windir%\SoftwareDistribution\ReportingEvents.log. If present, this indicates a corrupt local metadata store for Windows Update. SOLUTION: Click Start, click Run, type SERVICES.MSC, click OK. Stop the Automatic Updates service. Rename the c:\Windows\SoftwareDistribution folder to c:\Windows\SoftwareDistribution.old. Restart the Automatic Updates service. (Tip from MS-MVP Bill Castner.)
REBOOT ON SHUTDOWN WITH HARDWARE-ENFORCE DATA EXECUTION PREVENTION. If your computer uses hardware-enforced DEP, as the 64-bit AMD processors do, and you installed hardware that requires the MPEGPORT.SYS driver, there is a conflict. At shutdown, the driver tries to run from the same memory space DEP monitors. A 0xFC Stop message occurs. If your computer is set to automatically reboot on a system failure, it will simply reboot instead. The solution is a new driver. Microsoft provides a work-around in MSKB 878474.

OTHER KNOWN ISSUES & HINTS...

BIOS UPGRADE. As with every new operating system that comes along — especially one that is as much of a “step up” as Windows XP is from Windows 9x — the recommendation is made to be sure your BIOS is updated. Many people have reported that this has solved their shutdown problems (and had other advantages) with Win XP, just as it has in earlier versions of Windows.
“ShutNTdown” REGISTRY PATCH. Download the “ShutNTdown” Registry patch mentioned above under powerdown issues. Please follow sensible Registry editing protocol. Backup your Registry before the change (e.g, run System Restore to create a restore point). After installing, test Windows shutdown. If the fix doesn’t work for you, remove it by restoring the Registry to its prior state. This is not the appropriate shutdown fix for most machines, but does help some users with Windows shutdown problems, and not just with powerdown issues as one might suspect.
UNSIGNED DEVICE DRIVERS. Some users have found that Windows XP won’t shutdown properly if unsigned device drivers are used. This is simply a variation of the broader device driver issue: Hardware manufactures have not yet released all necessary device drivers for Win XP. This will continue to be a problem for the next few months; it already has been reduced to a very minor cause of Win XP shutdown problems.
SIGNED DEVICE DRIVERS ON TOP OF UNSIGNED ONES. Good advice on a variation of the above comes from correspondent Attila Szabadkai. For his SBLive 1024 sound card he had originally installed non-XP drivers, then updated these with digitally signed XP drivers downloaded from Creative Labs. Result: He got a 0x0A Stop Message at shutdown. SOLUTION: He removed all drivers, and put back only the digitally signed one.
PROGRAMS HANG / BECOME UNRESPONSIVE. Sometimes programs don’t close down correctly, or hang for some other reason during the Windows shutdown process. This freezes up, or at least significantly delays, Windows shutdown. For example, a few people have reported an error message that EXPLORER.EXE has become unresponsive during shutdown when they have used Win XP’s native CD-burning capabilities during that Windows session. If Windows is hanging because it can’t force a program to terminate, one solution is to disable the automatic end task logic (AutoEndTask). Use this registry patch to force that setting change. (Be sure to back up the Registry first.)
PACE INTERLOK ANTI-PIRACY SOFTWARE. According to the MS Knowledge Base article Computer Hangs During Shutdown Because of Resource Conflict, PACE InterLok anti-piracy software installs a driver (TPKD.SYS) that uses the same IRQ as the Standard Floppy Disk Controller device. This can cause Win XP to hang at a blank screen (with mouse and keyboard nonresponsive) when you try to shutdown or restart. Additional symptoms may be that the floppy drive doesn’t show in My Computer; the Standard Floppy Disk Controller device in Device Manager may display the error status “This device cannot find enough free resources that it can use. (Code 12)”; and/or when trying to shutdown from Safe Mode you get the error message, STOP 0x0000009F Driver_Power_State_Failure. The solution is to get the updated TPKD.SYS file from PACE.
QUICK-SWITCHING USER ACCOUNTS. One reported quirk affecting shutdown is the three-account shuffle. Windows XP gives the ability to rapidly bounce between user accounts, with Win+L. If at least three user accounts exist, and you quick-switch through all three, and then log off all three in reverse order — “backing out” in an orderly way — then the machine may hang on shutdown. There may be other variations of account shuffling that cause this, but this one, clear example was provided by newsgroup correspondent John Ward. Microsoft has now identified something similar as a bug, in MSKB 320008, “You May Not Be Able to Shut Down Your Windows XP Computer.” The situation they describe is that only one user is logged on, quick-switching is used, and “Windows is under heavy stress.” A supported patch is available; see the article for details.
USING SHUTDOWN SCRIPTS & 802.1x AUTHENTICATION PROTOCOL. This combination can cause Win XP to take in excess of 10 minutes to shutdown normally. (IEEE 802.1x is an authentication standard for both wireless networks and wired Ethernet networks.) Here’s how the dominoes fall: The 802.1x authentication protocol stops after the user logs off. Shutdown scripts run after the user logs off. If the script is on a network share and the connection is no longer available (since authentication has terminated), the script can’t run. The default time-out for shutdown scripts is 10 minutes. So the computer sits there 10 minutes before continuing with its shutdown. (Reference: MSKB 311787.)
MISMATCHED RAM. Correspondent Morten Bech reported that a combination of PC-100 and PC-133 RAM was the source of his shutdown problem. When he resolved the mismatch (by removing the PC-100 RAM), he also resolved the shutdown problem. A general reminder of a great general tip: You will get the best results if all RAM in a particular computer matches in all respects!
CHANGE NTFS TO FAT32? MOVE THE PAGEFILE? Correspondent “Curiefleas” wrote that his reboot-on-shutdown problem was solved when he used a third party partitioning program to convert his NTFS partition to FAT32. It isn’t clear why this would be the case, but the tip was worth passing along. In a possibly related vein, other correspondents have reported a shutdown problem in XP either being caused by, or resolved by, relocating the pagefile! Is there some common issue involving substantial moving of the hard drive’s contents? These two hints intrigued me in light of a seemingly dissociated shutdown problem reportedly occurring in Win ME only immediately after a defrag. These all may be unrelated to each other — or not. I list them here as part of the ongoing data collection.
SHUTDOWN PROBLEMS IN WINDOWS NT/2000. In researching known causes of shutdown problems in earlier versions of NT-family operating systems, most of what I found referred to problems that were resolved in later versions. There is no reason to suspect their recurrence. For example, there were quite a few shutdown issues identified in NT 3.x that didn’t survive to NT 4.0. Very predictable causes were involved most often, especially difficulty with some 16-bit applications or specific hardware incompatibilities. Very few shutdown failure scenarios are documented for Windows 2000. All that I found were conflicts with specific software, specific hardware, or drivers. While these three frame a wide set of possibilities, they are sufficiently narrow to be very encouraging when joined with what we are seeing with Win XP. If approved compatible hardware and software are used, including XP-specific drivers, we see almost no shutdown problems at all. If other hardware or software is used... well, that gives us a starting place to focus our investigations.
SHUTDOWN PROBLEMS IN WINDOWS 9x. As stated at the beginning, I recommend that, if nothing above resolves your Win XP shutdown problem, try those troubleshooting steps that have worked for Windows 9x operating systems to help us establish a track record of exactly what does and does not apply, from that protocol, to the emergent scenarios in Windows XP.

Tăng tốc Vista: Tắt bỏ 12 tính năng không cần thiết

Cập nhật lúc 14h18' ngày 08/09/2008

Xem thêm: tăng tốc vista, tính năng, không cần thiết, windows vista

Quản Trị Mạng - Phiên bản Windows mới nhất là một gói tổng hợp rất nhiều tính năng – nhiều hơn bất kỳ phiên bản Windows nào trước đây – và một vài trong số chúng chỉ là những tính năng không cần thiết. Tất cả những tính năng đó cũng là nguyên nhân gây ra việc chạy máy chậm. Thực hiện theo các bước trong bài này bạn có thể thu hồi lại được hiệu suất máy tính bằng cách loại bớt những tính năng không cần thiết.

Có hàng tá tính năng Vista không cần thiết bạn có thể tắt bỏ. Một vài hiệu ứng giao diện bóng bẩy chính là nguyên nhân gây chậm máy tính, trong khi một vài hiệu ứng khác gây tiêu tốn rất nhiều bộ nhớ.

Vậy có nhất thiết phải tắt bỏ tất cả các tính năng nêu ra trong bài này? Điều đó còn phụ thuộc vào máy tính, thói quen công việc và sở thích của bạn.

Để đảm bảo an toàn, bạn nên tạo điểm khôi phục trước khi tắt bất kỳ tính năng nào. Thông qua đó, nếu bạn không thích những sự thay đổi nào, có thể khôi phục lại chúng một cách nhanh chóng. Để tạo điểm khôi phục, kích vào Start nhập sysdm.cpl và nhấn Enter. Chọn System Protection > Create và thực hiện theo từng bước hướng dẫn.

Sidebar

Bạn phải tiêu tốn rất nhiều hiệu suất máy cho việc hiển thị đồng hồ, thumbnail slide-show ảnh và nhận thông tin RSS trên Windows Sidebar. Tắt bỏ những hiển thị này sẽ giúp máy tính hoạt động nhanh hơn rất nhiều, đặc biệt là khi khởi động máy.

Để tắt bỏ Sidebar, kích chuột phải vào bất kỳ vị trí nào trên Sidebar và chọn Close Sidebar. Bỏ tích tại mục Start Sidebar when Windows starts, và kích OK.

Giao diện Aero

Microsoft sử dụng rất nhiều hiệu ứng đẹp mắt thông qua giao diện Aero. Các tính năng trong giao diện này bao gồm việc hiển thị cửa sổ thumbnail khi đưa chuột vào các mục trên taskbar, hay như cách xem cửa sổ dạng Flip 3D khi nhấn phím Windows + Tab.

Rõ rằng là Aero rất phù hợp với những người thích giao diện bóng bẩy và đẹp mắt. Tuy nhiên nếu máy tính của bạn thường bị chậm và quá tải thì việc sử dụng Aero là một sai lầm. Hãy tắt bỏ nó bằng cách kích chuột phải vào nền màn hình Desktop và chọn Personalize > Window Color and Appearance. Trong hộp thoại Windows Color and Appearance, kích Open classic appearance properties for more color options (nếu bạn không thấy hộp thoại này có nghĩa là Aero trên máy đã được tắt). Chọn Windows Vista Basic và kích OK.

Một số tùy chọn giao diện tô điểm

Bạn có thể tiết kiệm thêm được khoảng thời gian dùng máy bằng cách tắt đi toàn bộ hoặc một số tùy chọn giao diện đẹp mắt của Vista.

Để xem các tùy chọn này, kích vào Start, chuột phải vào Computer và chọn Properties. Kích vào Advanced System Properties, chọn tab Advanced và sau đó kích vào nút Settings trong hộp thoại Performance.

Bạn có thể bỏ chọn tất cả các tùy chọn trong danh sách bằng cách kích vào Adjust for best performance, hoặc đơn giản chỉ cần bỏ chọn những tính năng không cần thiết. Trong danh sách này có thể bỏ chọn những thành phần sau: Fade or slide menus into view, Fade or slide ToolTips into view, Show shadows under menus, và Slide open combo boxes.

Remote Assistance

Không cần quan tâm về việc tắt tính năng này nếu bạn đang sử dụng Vista Home (Basic hay Premium), những phiên bản này không có tính năng Remote Assistance. Nếu bạn đang sử dụng Vista Business hay Ultimatem, có thể sử dụng Remote Assistance để điều khiển một máy tính khác – công cụ này rất hữu dụng nếu bạn thường xuyên phải hỗ trợ kỹ thuật cho những người sử dụng máy tính ở xa. Nếu bạn không thường xuyên phải hỗ trợ hoặc đã sử dụng phần mềm điều khiển từ xa của một hãng thứ ba, Remote Assistance lúc này chỉ có tác dụng tiêu tốn tài nguyên máy tính. Để tống khứ nó khỏi máy, bạn vào Start, kích chuột phải vào Computer và chọn Properties. Kích vào Remove Settings. Bỏ chọn phần Allow Remote Assistance connections to this computer.

Internet Printing Client

Bạn đã bao giờ in các tài liệu thông qua mạng Internet? Nếu chưa, hãy tắt bỏ đi tính năng Internet Printing Client trong Vista.

Mở bảng điều khiển Programs and Features, kích vào Turn Windows features on or off ở phía bên trái cửa sổ; hộp thoại Windows Features sẽ xuất hiện. Mở rộng phần Print Services và bỏ chọn phần Internet Printing Client.

Kích OK và sau đó đợi vài phút để hệ thống hỏi khởi động lại. Thao tác này cũng được áp dụng để bỏ đi 3 tùy chọn của các mục sau.

Windows Meeting Space

Windows có tích hợp sẵn chương trình cộng tác ngang hàng Meeting Space, chương trình sẽ giúp bạn chia sẻ các file ngang qua một mạng và có thể chỉnh sửa chúng từ xa. Tuy nhiên, không phải ngày nào bạn cũng sử dụng tính năng này.

Vì vậy, hãy tắt tính năng Windows Meeting Space đi nếu bạn thực sự không thường dùng. Chỉ cần bỏ chọn phần Windows Meeting Space trong hộp thoại Windows Features.

Windows Ultimate Extras

Một trong những thứ tốt nhất mà bạn có thể thực hiện trong phiên bản Vista Ultimate là tắt bỏ những tính năng vô dụng đi. Tôi đang đề cập tới Ultimate Extras, một tập hợp các add-on có thể download chỉ cho người dùng Ultimate. Nếu bạn không trả tiền cho phiên bản đắt nhất của Vista, những add-on vô dụng này không đáng bận tâm.

Bạn có thể tắt bỏ Windows Ultimate Extras trong bảng điều khiển Windows Features bằng cách kích vào Turn Windows features on or off để mở hộp thoại Windows Features, sau đó bỏ chọn tại mục Windows Ultimate Extras.

Tablet PC Stuff

Windows Vista có rất nhiều tính năng hỗ trợ sử dụng Tablet PC đặc biệt là tính năng Input Panel hỗ trợ viết bằng bút. Nhưng nếu bạn không sử dụng tablet, tính năng này sẽ là vô dụng. Tắt bỏ các tính năng tablet của Vista, thực hiện các bước sau: Mở hộp thoại Windows Features, bỏ chọn phần Tablet PC Optional Components. Vào menu Start, nhập services và nhấn Enter. Tìm và kích đúp vào phần Tablet PC Input Services. Trong menu thả xuống Startup type chọn Disabled và kích OK.

ReadyBoost

Tính năng này được giới thiệu là tăng tốc Vista bằng việc lưu bộ nhớ vào một ổ flash, tuy nhiên thực tế tính năng này cũng làm chậm chút ít hệ thống của bạn. Nếu không sử dụng đến tính năng này bao giờ, hãy tắt bỏ nó đi. Vào Start nhập services và nhấn Enter. Tìm và kích đúp vào mục ReadyBoost. Trong menu thả xuống Startup type chọn Disabled và kích OK.

Search Indexing

Đây là một tính năng thực sự cần sử dụng trên mọi máy tính. Tắt tính năng lập chỉ mục (index) của Vista sẽ làm chậm đi rất nhiều quá trình tìm kiếm thông tin trên máy tính của bạn. Nhưng bù lại đó, nó sẽ giúp máy tính có cải thiện rõ rệt về tốc độ.

Nói cách khác, việc tắt tính năng lập chỉ mục giúp máy tính nâng cao hiệu suất chỉ có lợi hoàn toàn khi bạn không sử dụng đến tính năng tìm kiếm nội dung file trên máy tính, hoặc nếu cần có thể sử dụng một công cụ tìm kiếm khác như Copernic Desktop hay Google Desktop.

Nếu bạn đã thực sự thấy cần tắt đi tính năng này, hãy vào menu Start, nhập services và nhấn Enter. Tìm và kích đúp vào mục Windows Search. Tại menu thả xuống Startup type, chọn Disabled và kích OK.

Offline Files

Nếu bạn làm việc trên các file được lưu trữ tại một máy chủ nào đó, và bạn không thể tin là máy chủ lúc nào cũng sẵn sàng để sử dụng, tính năng Offline Files của Vista Business và Ultimate giúp cho bạn đỡ lo lắng hơn bằng việc sao chép các file đó về ổ cứng máy tính bạn và giữ cho chúng luôn đồng bộ.

Tất nhiên, điều này không phải luôn cần thiết với tất cả mọi người, do đó Microsoft không đưa tính năng Offline Files này vào phiên bản Home của Vista. Tuy nhiên nếu bạn sử dụng Business hay Ultimate và vẫn không cần sử dụng Offline Files, hãy tắt bỏ tính năng này đi bằng cách kích vào Start, nhập services và nhấn Enter. Tìm và kích đúp vào mục Offline Files. Trong menu thả xuống Startup Type, chọn Disabled và kích OK.

Windows Error Reporting

Windows thường xuyên gửi đi các thông báo lỗi – kể cả từ quá trình xử lý của chính hệ điều hành cho tới hoạt động của phần mềm hãng thứ ba – nó đều cung cấp báo cáo lỗi về Microsoft. Theo lý thuyết, việc này sẽ giúp công ty xác định được các vấn đề đối với hệ điều hành của họ. Tuy nhiên, những báo cáo này không phải lúc nào cũng được giải quyết và máy tính của bạn lại phải thực hiện thường xuyên công việc này (thậm chí là lặp lại các vấn đề giống nhau). Do đó, bạn đang lãng phí tài nguyên quý báu trên hệ thống của mình vào một tính năng hoạt động không cần thiết.

Hãy vô hiệu hóa tính năng này đi bằng cách: kích Start, nhập services và nhấn Enter. Tìm và kích đúp vào mục Windows Error Reporting Service. Trong menu thả xuống Startup type, chọn Disabled và kích OK.

UAC: món quà hay điều phiền hà?

Một trong những tính năng mới gây tranh cãi nhiều nhất của Vista là User Account Control (UAC), tính năng này giúp bảo vệ hệ thống trước mã độc bằng cách bắt bạn xác nhận hành đồng đang diễn ra đối với hệ thống (dù hành động đó do bạn thực hiện) vào mọi thời điểm. Đối với một số người thì hành động này là sự quấy rầy không cần thiết cần phải loại bỏ. Một số người khác thì cho rằng nó sẽ giúp hệ thống bảo mật hơn. Do đó, việc tắt bỏ hay sử dụng hệ thống này còn tùy thuộc vào bạn. Nhưng hãy lưu ý rằng, nếu bạn tắt bỏ tính năng này thì phải đảm bảo hệ thống của bạn đã có một vài chương trình bảo vệ mạnh.

Giả lập Windows Mobile 6.0 trên máy tính

17/12/2007, 08:44

Windows Mobile 6 (WM6) là hệ điều hành mới nhất dành cho các thiết bị di động của Microsoft. WM6 có 2 phiên bản hướng theo loại màn hình của thiết bị: bản standard hướng đến thiết bị không có màn hình cảm ứng (như Smartphone); bản professional hướng đến thiết bị có màn hình cảm ứng.

Tương ứng với 2 phiên bản trên là 2 phiên bản mô phỏng chạy trên Hệ điều hành Windows XP/2003/Vista. Với bản mô phỏng này, người sử dụng có thể cài đặt, thử nghiệm các chương trình trên máy mô phỏng mà không cần cài vào thiết bị.

1. Download

Có thể download các image của WM6 tại đây.

Trên site ở đường dẫn trên, có thể download file Windows Mobile 6 Standard Images (USA).msi (73.3 MB). File này chứa các giao diện như sau:

+ Windows Mobile 6 Standard (176x220 pixels - 96 dpi)
+ Windows Mobile 6 Standard Landscape QVGA (240x320 pixels - 131 dpi)
+ Windows Mobile 6 Standard QVGA (320x240 pixels - 131 dpi)

Hoặc có thể download file Windows Mobile 6 Professional Images (USA).msi (183.1 MB). File này chứa các giao diện như sau:

+ Windows Mobile 6 Classic (240x320 pixels - 96 dpi)
+ Windows Mobile 6 Professional (240x320 pixels - 96 dpi)
+ Windows Mobile 6 Professional Square (240x240 pixels - 96 dpi)
+ Windows Mobile 6 Professional Square QVGA (320x320 pixels - 128 dpi)
+ Windows Mobile 6 Professional Square VGA (480x480 pixels - 192 dpi)
+ Windows Mobile 6 Professional VGA (480x640 pixels - 192 dpi)

2. Yêu cầu cho WM6 Emulator

- Hệ điều hành hỗ trợ: Windows 2000 SP4, XP, 2003, Vista. Bài viết này sẽ hướng dẫn trên Windows XP. Các hệ điều hành khác, bạn đọc tự nghiên cứu.
- Trên Windows 2000/XP/2003, download ActiveSync V4.5: http://www.microsoft.com/windowsmobile/activesync/activesync45.mspx
- Microsoft .NET Compact Framework: tại đây

3. Hướng dẫn sử dụng

- Sau khi download WM6 Standard; WM6 Professional; ActiveSync, lần lượt cài đặt các chương trình. Quá trị cài đặt khá đơn giản. Khi kết thúc cài đặt ActiveSync, khởi động lại máy tính.

- WM6 sau khi cài đặt sẽ theo đường dẫn Start -> Programs -> Windows Mobile 6 SDK. Các skin sẽ nằm trong Standalone Emulator Images -> US US English. Để chạy một mô phỏng của WM6, chọn đường dẫn Start -> Programs -> Windows Mobile 6 SDK -> Standalone Emulator Images -> US English, sau đó chọn skin tương ứng. Ví dụ Windows Mobile 6 Standard Landscape, chọn -> Standard Landscape. Giao diện của mô phỏng WM6 tương ứng như hình dưới.

WM6 Standard Landscape

a. Save State and Exit

Save State and Exit là chức năng cho phép lưu trạng thái hiện thời của mô phỏng WM6. Sau khi cài đặt, cấu hình trên mô phỏng WM6, chọn chức năng này để lưu lại các thông tin. Để chạy chức năng này, chọn menu File -> Save State and Exit. Các file Save State sẽ được lưu lại theo đường dẫn Documents and SettingsApplication DataMicrosoftDevice Emulator, trong đó sẽ tương ứng với tên user đang sử dụng Windows XP. Sau khi lưu lại trạng thái của mô phỏng WM6, khác với mô phỏng WM5, chỉ cần chạy lại là sẽ WM6 Save State sẽ ngầm định được nạp lại.

WM6 Professional Square

b. Reset

Mô phỏng WM6 có 2 chức năng là Hard Reset và Soft Reset. Hai chức năng này có thể tìm thấy ở menu File -> Reset. Soft Reset là việc khởi động lại hệ điều hành WM6. Còn Hard Reset sẽ nạp lại cả hệ điều hành của WM6, xóa hết các thông tin trên thiết bị. Các chức năng này cũng tương tự như máy thật.

c. Share Folder

Lựa chọn từ menu File -> Configure cho phép cấu hình các thông tin liên quan đến máy mô phỏng.

Emulator Properties

Trong các tab của Emulator Properties, cần chú ý đến tab General với lựa chọn Share Folder. Như đã biết khả năng lưu trữ của PPC/Smarphon rất thấp, chỉ khoảng 64-128 MB. Muốn tăng khả năng lưu trữ này, cần cắm thêm thẻ nhớ. Chức năng Share Folder sẽ cho phép máy mô phỏng sử dụng một thư mục của ổ cứng máy tính trên Windows XP để làm ổ lưu trữ (Storage).

d. Kết nối với Windows XP thông qua ActiveSync

Đối với thiết bị thật sử dụng hệ điều hành Windows Mobile, để kết nối với PC, cần sử dụng cable USB (hoặc COM, hoặc IR), và trên PC dùng Windows, cần cài đặt chương trình ActiveSync.

Trên máy mô phỏng, việc kết nối này sẽ được thực hiện theo các bước sau:

- Cài đặt ActiveSync. Sau khi cài đặt, chạy ActiveSync theo đường dẫn Start -> Programs ->Microsoft ActiveSync.

Microsoft ActiveSync

Trên Microsoft ActiveSync, nhắp chuột vào menu File -> Connection Settings, xuất hiện hộp thoại Connection Settings. Trên hộp thoại Connection Settings, lựa chọn Allow connections to one of the following, trong danh sách các cổng kết nối, chọn DMA, sau đó nhắp nút OK để kết thúc việc thiết lập connection.

- Chạy máy mô phỏng.

- Chạy chương trình Device Emulator Manager theo đường dẫn Start -> Programs -> Windows Mobile 6 SDK -> Tools -> Device Emulator Manager.

Device Emulator Manager

Trên giao diện của Device Emulator Manager, nhắp đúp vào mục Other để mở các kết nối từ PC đến các Windows Mobile thông qua ActiveSync. Chuột phải vào một kết nối, trên menu chuột phải, chọn Cradle.

Khi đó ActiveSync sẽ tự động dò tìm thiết bị kết nối và xuất hiện hộp thoại Synchronization Setup Wizard. Hộp thoại này cho phép cấu hình các chương trình đồng bộ giữa máy tính và thiết bị sử dụng Windows Mobile.

Synchronization Setup Wizard

Sau khi kết nối, Microsoft ActiveSync sẽ có các lựa chọn Sync để đồng bộ chương trình giữa máy tính và thiết bị sử dụng Windows Mobile. Lựa chọn Explorer để mở ổ lưu trữ trên thiết bị.

ActiveSync sau khi kết nối

e. Cài đặt chương trình cho máy mô phỏng.

Chương trình cài đặt cho Windows Mobile nói chung có 2 dạng, dạng file exe để chạy trên máy tính và dạng .cab để cài trên Windows Mobile.

Với dạng .exe, cần chạy ActiveSync. Sau khi kết nối giữa PC và máy mô phỏng WM6, chạy file .exe đó trên máy tính. Khi đó chương trình cài đặt sẽ tự động kết nối và trên máy mô phỏng sẽ được hỏi cài đặt vào ổ lưu trữ của máy mô phỏng hay Storage.

Chú ý mục c. Share Folder để dùng 1 thư mục trên máy tính thật làm Storage trên máy mô phỏng và nên cài các chương trình vào Storage.

Với dạng .cab, chỉ cần copy các file .cab vào thư mục chia sẻ. Khi đó trên máy mô phỏng, dùng explorer để mở đến Storage và chạy các file này để cài đặt.

Bài viết trên trình bầy những kiến thức cơ bản về việc sử dụng máy mô phỏng cho Windows Mobile V6. Với máy mô phỏng, người dùng có thể thực hiện việc cài đặt, thử nghiệm các tính năng của chương trình mới, trước khi cài đặt lên thiết bị thật.

How To Repair MySQL Replication

Version 1.0
Author: Falko Timme
Last edited 05/29/2008

If you have set up MySQL replication, you probably know this problem: sometimes there are invalid MySQL queries which cause the replication to not work anymore. In this short guide I explain how you can repair the replication on the MySQL slave without the need to set it up from scratch again.

I do not issue any guarantee that this will work for you!

1 Identifying The Problem

To find out whether replication is/is not working and what has caused to stop it, you can take a look at the logs. On Debian, for example, MySQL logs to /var/log/syslog:

grep mysql /var/log/syslog

server1:/home/admin# grep mysql /var/log/syslog

May 29 09:56:08 http2 mysqld[1380]: 080529 9:56:08 [ERROR] Slave: Error 'Table 'mydb.taggregate_temp_1212047760' doesn't exist' on query. Default database: 'mydb'. Query: 'UPDATE thread AS thread,taggregate_temp_1212047760 AS aggregate
May 29 09:56:08 http2 mysqld[1380]: ^ISET thread.views = thread.views + aggregate.views
May 29 09:56:08 http2 mysqld[1380]: ^IWHERE thread.threadid = aggregate.threadid', Error_code: 1146
May 29 09:56:08 http2 mysqld[1380]: 080529 9:56:08 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'mysql-bin.001079' position 203015142
server1:/home/admin#

You can see what query caused the error, and at what log position the replication stopped.

To verify that the replication is really not working, log in to MySQL:

mysql -u root -p

On the MySQL shell, run:

mysql> SHOW SLAVE STATUS \G

If one of Slave_IO_Running or Slave_SQL_Running is set to No, then the replication is broken:

mysql> SHOW SLAVE STATUS \G
*************************** 1. row ***************************

mysql>

2 Repairing The Replication

Just to go sure, we stop the slave:

mysql> STOP SLAVE;

Fixing the problem is actually quite easy. We tell the slave to simply skip the invalid SQL query:

mysql> SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;

This tells the slave to skip one query (which is the invalid one that caused the replication to stop). If you'd like to skip two queries, you'd use SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 2; instead and so on.

That's it already. Now we can start the slave again...

mysql> START SLAVE;

... and check if replication is working again:

mysql> SHOW SLAVE STATUS \G

mysql> SHOW SLAVE STATUS \G

*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event
Master_Host: 1.2.3.4
Master_User: slave_user

Slave_SQL_Running: Yes

mysql>

As you see, both Slave_IO_Running and Slave_SQL_Running are set to Yes now.

Now leave the MySQL shell...

mysql> quit;

... and check the log again:

grep mysql /var/log/syslog

server1:/home/admin# grep mysql /var/log/syslog

May 29 09:56:08 http2 mysqld[1380]: 080529 9:56:08 [ERROR] Slave: Error 'Table 'mydb.taggregate_temp_1212047760' doesn't exist' on query. Default database: 'mydb'. Query: 'UPDATE thread AS thread,taggregate_temp_1212047760 AS aggregate

server1:/home/admin#

The last line says that replication has started again, and if you see no errors after that line, everything is ok.

Install VMware Server 1.0.5 on Ubuntu 8.04 “Hardy”

2008-08-03T20:29:00.008+07:00

Install VMware Server 1.0.5 on Ubuntu 8.04 “Hardy”

Filed Under virtualization

UPDATE: This tutorial has been updated for VMware Server 1.0.6. See the updated instructions here, at How To Install VMware Server 1.0.6 on Ubuntu 8.04.

Now that most of the modern world has upgraded to Ubuntu 8.04 I’ve begun to see comments regarding VMware Server no longer working. You may have used my previous article, Installing VMware Server on Ubuntu 7.10, which has worked great. Now that 8.04 “Hardy” is installed things have become a bit more complicated unfortunately.

The problem is that VMware has not updated their latest versions to make use of the latest kernel, GCC or gnome libraries. So, we’ve got two options.

Wait for a new VMware release and hope they patch everything.
Follow the rest of this tutorial and get your hands dirty on the terminal. We can make it work, but we have to hammer it into submission.

So, I’ll assume because you’re still reading that you’ve opted for the hammer into submission option. Let’s get started.

Downloading the Requirements

The first step, of course, is to download VMware Server 1.0.5. You’ll have to agree to the EULA (actually twice. Once before download and once during installation. Remember, VMware is free-as-in-beer but not free-as-in-speech.)

The second step is to install some development tools that we’ll need to get things running. Use the following command or click the package names to install the requirements:

sudo aptitude install build-essential linux-kernel-devel linux-headers-generic xinetd

The third step is to download one more tool to help in the manual build process for VMware Server 1.0.5. What we need is a script which will help in the custom config hosted at Google Code. Download the vmware-any-any-update-116.tgz.

You will also need to generate a serial number to run VMware Server. Visit this link to register and generate the number of codes you might want. Remember to print the codes or write them down because in my experience they are not emailed to you.

OK, at this point we should have all of the requirements, now we can get to work…

Installation and Configuration

Let’s unpack the VMware archive that we downloaded and run the VMware installer. NOTE: After some basic configuration it will ask you to run vmware-config.pl. DO NOT RUN vmware-config.pl, WE ARE NOT READY YET.

tar xf VMware-server-1.0.5 cd vmware-server-distrib sudo ./vmware-install.pl

When it asks you to run vmware-config.pl you want to answer “no” and this is where the vmware-any-any-116.tgz patch comes in.

cd .. tar xf vmware-any-any-update-116.tgz cd vmware-any-any-update116 sudo ./runme.pl

After this runs it will ask you again if you want to run vmware-config.pl. At this point select “yes”.

The Last Step

If you attempt to run vmware at this point you might notice that it spits out some nasty errors and complains at you. There is one more thing we need to setup. (Hey, VMware, if you’re reading this will you please incorporate these fixes into your official download already!)

Basically VMware is missing and complaining about some cairo libraries and gcc. So, the simple fix for this is to point to them by using a symbolic link:

sudo ln -sf /usr/lib/gcc/i486-linux-gnu/4.2.3/libgcc_s.so /usr/lib/vmware/lib/libgcc_s.so.1/libgcc_s.so.1
sudo ln -sf /usr/lib/libpng12.so.0 /usr/lib/vmware/lib/libpng12.so.0/libpng12.so.0

At this point you should be able to launch vmware and enjoy some virtualization goodness. Please stay tuned for virtualization updates regarding virtualbox and the new KVM!

sources: I want to throw a big thanks to my buddy Igor for helping figure out these tweaks. Check out his blog, with these and other instructions, here.

UPDATE: based on some of the comments below I’ve added the “-f” to the symbolik link options.

Virtual box in Ubuntu - Installation

March 24, 2008 by taufanlubis

If you need to run other Operating System in Ubuntu, you have to use a Virtual Machine. There are few most used Virtual Machines available on the internet, Virtual Box is one of them.

I like to use Virtual Box because it’s easy to operate.

Installation

From Ubuntu Terminal screen (Applications > Accessories > Terminal), type:

taufanlubis@toshiba:~$ sudo apt-get install virtualbox

To get Compiz Fusion up and running you need to install your Restricted Drivers.

System>Administration>Hardware Drivers

Restart your PC, then to enable Compiz Fusion open a terminal.

Applications>Accessories>Terminal then copy and paste

sudo aptitude install compizconfig-settings-manager

Then hit enter.

You may also like to install Emerald, again in the Terminal copy and paste

sudo apt-get install emerald

Then hit enter.

đây là hiện tượng vừa gặp sáng nay, làm mất cả buổi sáng không thể log vào KDE desktop được
-Tương Kernel mơi build hôm qua có vẫn đề -> thêm 1 số parameter cho kernel, build lại -> thất bại
- Kiếm file xorg.conf để chỉnh sữa mà kiếm miết không ra -> bó giò
-search tài liệu google + www.freebsd.org documents lần nữa, ra được cái này ->
--> kết luận: Hiểu thêm 1 chút về xorg nữa
Không hiểu vấn để là tại sao nhưng cuối cùng cũng giải quyết được

First Cup of Ubuntu

Question: ( this is the same with my problem)

Hello,

I am using Kubuntu 6.06.
Onboard graphics: NVIDIA GeForce 6100
I have used a resolution of 1024x768@85 for a few months without problems using "nvidia" driver. GLX worked great too.
One day when I booted my PC suddenly it only allowed one low resolution and refresh rate.
I tried dozens of xorg.conf configurations, removed and re-installed nvidia drivers using synaptic, using the .run executable from nvidia server and using automatix2. None of them worked.

xrandr will only output one line with 800 x 600 @ 60 resolution.

Right now I am using "nv" driver and it works, although it is only 1024x768@79 when it should be 85Hz.

This is my current xorg.conf that works with "nv" driver, but only at low resolution with "nvidia" driver:

Code:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

I did, the current configuration I am using now was made this way.
I have a full list when I type xrandr and use "nv" driver, but as soon as I switch to "nvidia" driver, there is only one line.

Introduction

Headers are short fragments of text which are generated by servers to hold information pertaining to each transfer as it occurs. There are four kinds of headers:

General

This holds information about the client (user), the server itself and the protocol being used (like http or ftp). Entity This holds information about the data that is being transferred.

Request

This holds information about the allowable formats and parameters for the transfer.

Response

This is sent out by the server at the end of a transfer, and includes detailed information, in code form, on the outcome of the transfer.
