Hi,
A system running redhat 7.0 has redhat ppp dialer problem (rp3). The
system is setup properly but suddenly the dialer started to misbehave,
it thaught it was connected when it was not. Using the redhat dialup
configurator "debug" button sometimes works fine and sometimes indicate
it's connected when it is not and pressing "hangup" button don't work.

Trying to stop/start the interface using the RH dialer only wouldn't
help as the dialer would say "Failed to connect to interface". Rebooting
didn't help either.

-what is the best thing to do?
-Is there any files containing the state of the dialer to edit? Any task
to delete?
-How does the dialer knows it's connected?

thanks
