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.
