How to undo 'chmod u+s `which kppp`'
 

I am using RedHat Linux 9 and entered the following commands in order to get non-root dialup:

chmod u+s `which kppp`
chmod u+s `which pppd`

Now I get no response when I choose the Kppp item from the KDE menu in RedHat and cannot start kppp except as root. This is the opposite of what I was trying to achieve. When I type the command for kppp from a terminal as a non root user I also get no response. Before I entered the above commands the same action would ask me for my root password and then proceed to start up kppp

How do I undo the above commands and restore the menu response in KDE?

Any help would be much appreciated.

well you can do the opposite of what was done, to remove it:
chmod -s kppp
chmod -s pppd

To undo just do the opposite of what you did

chmod u-s `which kppp`
chmod u-s `which pp

When trying to give users acces you don't need to mess with pppd just kppp. And leave out the which

chmod u+s /sbin/kppp

Many thanks.
