Linux Windows System Administrator Help

Whenever you are trying to upload an image using the flash uploader in Wordpress and received a “HTTP error”? and uploading images status stuck in crunching ……..

Here solutions::

The problem has something to do with mod_security, which is basically a web application firewall that protects your website from a range of attacks. So you shouldn’t turn off this module as it protects your site from such malicious attack , You can add a special rule in .htaccess file which can be found in the root folder of your Wordpress installation to get work the flash uploader.

Open the .htaccess file in your website document root and add the following lines:

• For Apache 1.X
  

  <IfModule mod_security.c>
  <Files async-upload.php>
  SecFilterEngine Off
  SecFilterScanPOST Off
  </Files>
  </IfModule>

• For Apache 2.X
  

  <IfModule mod_security2.c>
  <Files async-upload.php>
  SecRuleEngine Off
  SecAuditEngine Off
  </Files>
  </IfModule>

Then try to upload the images it should be work like charm D:

Have you thought of hiding what you are doing on your linux bash shell prompt? and not allowing your colleague to see what command you are entering or do you want to confuse your colleague by showing something invisible but work as visible? then read out this…

Today I came across a neat, but pointless shell command. By running the following in shell, it will hide any commands you run.

root@server2 [/]# stty -echo

In order to disable this mode, simply remove the “-” before echo.

root@server2 [/]# stty echo

I guess there really is no point to the command, though you could always mess with your coworkers if they leave their shell prompt open

Cheers.
