This is probably yhe simply way to change Admin password on oScommerce.

You can do it if you use cPanel to manage your website, if you use other panel way to proceed is similar.

Go to cPanel user account.
1. On “Web Protect” under the Site Management Tools menu.
2. Go to the folder you want to change (eg. /oscommerce/admin/)
3. Now you can change, add or delete usernames and passwords for that folder.

Note that you can even set it up so multiple persons can have passwords and usernames.

If you are running cPanel, you can use the next command to check if ImageMagick is running:

# /scripts/checkimagemagick

If you want to install ImageMagick on cPanel you can use this script:

# /scripts/installimagemagick

Note that: This feature of cPanel is unsupported since it doesn't provide true ASP support so, if you need full ASP support on your linux server you shoukd contact Sun Java ASP.

Log in into your cPanel server and run the next script:

# /scripts/installpostgres

This script will help you to install PostgreSQL on your cPanel Server.

Then you need to run the easyapache script to add in PostgreSQL support if you want to use it with PHP.

If you are running a cPanel Server, your priority administration task should be the security. Some tricks about Server Security can be read on this blog. If you are running a WebHosting business you should provide to your costumers the high security level. A basic security need is to keep cPanel last stable version.

To see if you are running the last cPanel version on you Server or VPS, just login as root and run the next command:

# /usr/local/cpanel/cpanel -V

If you need to update cPanel user:

# /scripts/upcp

or if you want to force it:

# /scripts/upcp --force

Take in mind that keep you server with the last cPanel version is not suficient to keep the server secure. It is a long process and you should keep allways you eye open. Good look :-)

This basic article will help you to speed up your PC

1. Defrag your computer at least once every two weeks (I do it once a week). Go to start>accessories>system tools>disk defragmenter. You can click on "analyze" first before you choose defrag, it will tell you if you need to defrag. Just defrag it even if it reports you don't need to.

2. Do Disk Clean Up at least once every two weeks (again, I do this once a week). Go to start>accessories>system tools>disk clean up. It will analyze your disk and will generate reports. I suggest you delete files from the recycle bin and the files located in the temporary files folder. Note: I avoid compressing files. It's your call.

3. Clean up your program files, delete and uninstall unwanted programs on your computer. Go to control panel>add remove programs. Make sure you restart your computer after uninstalling or removing the program so that complete deletion will take place.

4. Delete all files (temporary files and cookies from the computer). Here's how: open a browser. On top of the browser click on tools>internet options>delete files and then delete cookies. Make your history set to (0). Others wants it on at least 10. I always set mine to (0).

5. You have to be very careful in installing or downloading programs. Make sure you need it, if not please just avoid it. Uninstalling them is really hard. Many vendors has all the power to have their program stay in your computer!

6. Always turn on your firewall. I suggest you have only one firewall and one anti virus. You get less safer if you have two anti virus running (I know people who likes to have two anti virus programs running on their computer, I don't know why.)

7. Run anti-spyware programs. I trust spybot, search and destroy and the Adware from Lavasoft. I run SD every week, I do immunize them before I do the the entire program to run. I run adware every week too after I run spybot search and destroy.

8. Run complete scan using your antivirus software at least everyday (some do it once a week). Mine is scheduled at 3:00am everyday.

9. Avoid multi-tasking too much! Meaning to say, avoid opening too many programs all at the same time running at the task bar.


10. I also suggest you get a dual hard drive (which I know is now common in the market), one for the operating system only and the other for all the programs, database and files. This way, the computer boots on one hard drive.

11. Also check the performance of your computer when connected on the internet. Go to control panel >network and internet connections >network connections >right click the mouse on the connection available (e.g. local area connection "connected", "firewalled")>click on "STATUS". Make sure on the status tab, you will see the speed (mine is always 100 mbps). The packets sent and the packets received must not have a very high difference. If it is sending too much packets (as in ten times) than it receive (then try to do number 7!).

12. Always make sure you install the latest updates on your computer.


13. Always make sure all devices (drivers, etc) are properly functioning. Go to control panel >performance and maintenance >system >hardware >click on DEVICE MANAGER. You will see all the devices and adapters available on your computer. Make sure you don't see a yellow question mark (?) or this means there is an error on that device or adapter. If so, you need to update it or install the right drivers. Updated firmware might also be needed.

14. Browsing the internet? well, I have my google toolbar installed on my computer and is my default search engine. Their pop up blocker is really great!

15. A memory of at least 512 RAM might be a good idea installed on your computer

You can check the size of a folder running this command:

# du -hs /folder/

When you log int your server you get some error like this:
/tmp/Rs6V6BOv: Disk quota exceeded

Probably cpanel is not running and users cant send files using FTP.

Probabaly you ran out of inodes.

Run this command:
# df -i

And check if any partition is 100%.

Inodes are related to number of files you have under a directory and not to the disk space used, you should be having a large number of tmp files or a huge mail queue.

You can check the tmp files on this file: /var/tmp and mail queue on this /var/spool/exim/input/

jusched.exe description:

Running windows task maneger you should find jusched.exe, that program is a process info for Sun Java Update Scheduler, it is not an virus .

If you get this error:



Or one of these:
Cannot delete file: Access is denied
There has been a sharing violation.
The source or destination file may be in use.
The file is in use by another program or user.
Make sure the disk is not full or write-protected and that the file is not currently in use.

You can use this free tool to delete the file or folder:
UNLOCKER

DOWNLOAD UNLOCKER

Method 1

Reboot, then delete.

Method 2

Open a command line window (WindowsKey + R, enter: cmd). Move to the folder in question by means of CD commands like CD \ and CD foldername.

Delete the file or folder by using the DEL command to delete files or the RMDIR (remove directory) command to remove directories (folders).

Method 3

If this, on its own, is still not enough, then leave the command line window on the desktop, open Task Manager (Ctrl + Shift + Esc), and kill all explorer.exe tasks. Your desktop will go blank, except for the windows already open.

Now try to delete the offending file by means of the DEL command, or folder by means of the RMDIR (remove directory) command, in the command line window, as described above.

After that, in the command line window enter:

explorer

to restart your desktop. If you closed the command line window, you can still restart explorer by opening the Task Manager by holding down the Ctrl and Shift keys and briefly pressing the Esc key. In Task Manager select Applications, New Task and enter: explorer

Method 4

If the previous method fails, particularly with multimedia files, log off, then log on again, but do not select the file in Windows Explorer. The safest way is not to open Windows Explorer in the first place.

Then try the previous method again.

Method 5

An even stronger measure would be to reboot, then try the previous methods again. This would work, for example, if a service has the file open.

Method 6

[Thanks to John Barrington:] If you can't delete a problem file, try deleting the folder that contains the problem file. If this doesn't work, try this next item.

If the problem file and its folder, we'll call (A), is within another folder, we'll call (B), try to delete the folder (B) along with any troublesome contents.

Of course, you want to make sure, if you have any other important files or folders within either folder, that they are saved in another location first.

Method 7

Begin like the previous method, but try also

rmdir /s foldername

(replace foldernamewith the name of the folder to be deleted). This command should delete a folder with all its subfolders.

If the folder name contains one or more spaces, enclose it in quotes. Example:

rmdir /s "folder name"

Note that the abbreviated command rd can be used in place of rmdir.

Method 8

If the folder name contains strange characters, use a command line window again, but use the DIR /X command to find the short name (for example: PROGRA~1) and use the short name instead. The short name is DOS compatible and has no more than 8 characters for the main name, a period, then no more than 3 characters for the extension.

Retry the previous methods that use a command line window, but use the short name now.

Note: Sometimes an illegal file name can cause Windows Explorer to use nearly 100% of the CPU time.

Sometimes the abbreviated name can have a number other than one and can have an extension. If the above does not work, proceed as follows.

1. Open a command line window (Start, Run, type: cmd, press the return/enter key).
2. Navigate to the folder using "cd .." and "cd pathname", where pathname is the name of the next subfolder you want to go into.
3. Type dir /x to see the actual real short name of the subdirectory. Critically: This may include an extension, e.g. "ABDCEF~1.XYZ".
4. Type "rmdir /s abcdef~1.xyz", replacing the example name abcdef~1.xyz with your actual folder name.

Method 9

Boot into safe mode and try to delete the file or folder there.

Method 10

If you're trying to delete a program file, like one with the extension .exe, the cause could be that the program is currently running. Stop it, then delete the file.

If the program starts automatically, check the article Autorun causes on how to remove the start command. Do it, reboot, then delete the file.

Method 11

If this also doesn't work, there is a way to rename a file or folder during the boot process. For this you need to use the registry editor REGEDIT.EXE. See the Registry warning for a general warning.

Create an entry in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Session Manager\

named PendingFileRenameOperations of type REG_MULTI_SZ. In pre-XP Windows versions you have to use REGEDT32.EXE to create this value type.

The first line of each pair is the current file or folder path and name with \??\ in front of it.

The second line of each pair is the new file or folder path and name with !\??\ in front of it.

Example for one pair which moves the file mfc42.dll from the temp folder to the system32 folder and overwrites any existing file at the destination:

\??\C:\TEMP\mfc42.dll
!\??\C:\WINDOWS\system32\mfc42.dll

You can add as many pairs as you like. The move operation is performed directly after the next reboot. You can also give folder paths, so the folder will be renamed. But both paths have to be local.

There is a Windows API call for this, named MoveFileEx, and somebody in Germany has even written a utility named MoveEx for it. You can download it from http://wwwthep.physik.uni-mainz.de/~frink/nt.html. Use it if you need this function often. A Posix utility from a Windows Resource Kit named mv.exe also does it, just in case you still have the resource kit around.

Method 12

Boot into another operating system to delete the file from there. The other operating system can be, for example, another installation of Windows, BartPE, Knoppix, or any operating system that can read the file system used (NTFS or FAT32).

Method 13

Remove the hard disk from the computer and connect it to another computer. Delete the files or folders there.

Method 14

If you cannot delete a file or folder because it is in use, you can use one of the mostly free utilities, such as Unlocker.

Method 15

If the cause is that the path and file name is too long, first try to rename folders in the path with shorter names.

If that doesn't work, you can use the following method, reported 2007-05-17 by Mark Briody:

Open a command line window and use the subst command to create a virtual drive to the folder containing the long file name, e.g. (all in one line):

subst x: "C:\Documents and Settings\briodym\Favorites\Mark\Gadgets and Hardware\Hardware\Stores\eBuyer"

Then change to the virtual drive x:, and you should be able to delete, rename, and move files and folders.

Finally, to clean up, remove the subst again with:

subst x: /d

What is Vsp1cln.exe (Vista SP1 File Removal Tool)?

Vsp1cln.exe is an optional tool that you can run after you install SP1. This tool removes older versions of components that have been updated in SP1, which are stored during the installation in case you need to uninstall SP1 later. Saving these older components increases the amount of disk space that is used. Typically, you should run Vsp1cln.exe if you want to reclaim this disk space after applying SP1 and if you will not need to uninstall SP1. Note, however, that you cannot uninstall SP1 after you run this tool.

You will get more free space on your computare after run this tool. You can read more about Vista SP1 File Removal Tool
