Undo chmod u+s `which kppp`

[Bill Dika]

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.

Regards,
Bill Dika

I don't know if this will help you with your dialup problems, but to
remove the suid bit, you can simply use

chmod u-s 'which kppp'

Nice idea, wrong execution.

All your questions are loaded, presumably because of wrong assumptions.
"undoing" is just a question of replacing a + with a - in your command,
unless you know something I don't about the original perms. What were
they? Just reestablish them.

The real problem here is that you are applying your chmod to the wrong
thing. The kppp in your path is not the kppp that you want to run -
it's only a shell that asks for the root password and starts the real
kppp. It's the real kppp that you want to make suid and executable by
you, and it's the real kppp that you want to run. Ditto pppd, if
you care.

Stop messing up.

chmod u-s `which kppp`
I don't have kppp, but pppd on my Debian system is u+s.
