application need root permission to run
 

Hi all,
I am new member to this group. how i can give root permissions to an application so that it can run on simple user. i mean like wire shark application to capture the packets.

Have you tried using "sudo" ? Try reading http://www.unixtutorial.org/2008/01/sudo-tutorial/ (or any other tutorial) if you haven't :)

Hope this helps,

you can also setuid the executable, but using sudo is cleaner and better. See here if you don't know what I'm talking about.

You could also modify the permissions of the application so that it can be used by a regular user without requiring a password; 'ping' is one such application.

This is how you would do this:
where <app> is the name of your application. You must be logged in as root (or use sudo) to perform the commands above.
