File Permission

I first encountered file permission problems when I first uploaded my CGI scripts. When I tried to execute the script, the Apache server returned 'permission denied' error message. If you go through this article, you will not encounter any such problem, better still, even if you encounter one, you will be in a position to solve it.

How to Change File Permission

File permission of a particular directory or file can be changed in two ways:

1. Using telnet
2. Using FTP software. Two free FTP softwares(for Windows) that support this feature are:
   • WS FTP LE - Right click on the file to change permission. Select 'chmod'.
   • FTP Works(Buggy) - Select the file, click the 'chmod' button on the right.

• For Directories & Executable files
  Use the following command if you have logged in using telnet:
  chmod 755 <filename>
  
  If you are using GUI FTP clients, change the permission to:

  	Owner	Group	Other
  Read	x	x	x
  Write	x
  Execute	x	x	x

  If you are more concerned about security:

  	Owner	Group	Other
  Read	x
  Write	x
  Execute	x	x	x

• For Other Files
  Give the following command in the telnet prompt:
  chmod 644 <filename>
  
  For GUI FTP client users:

  	Owner	Group	Other
  Read	x	x	x
  Write	x
