Sorry.

Issuing pppd at servis' prompt without any options send LCP packets
to the tty and the following in the log.

Aug 26 16:30:33 brian pppd[3840]: pppd 2.3.5 started by servis, uid 6262
Aug 26 16:30:33 brian pppd[3840]: Using interface ppp0
Aug 26 16:30:33 brian pppd[3840]: Connect: ppp0 <--> /dev/ttyp0
Aug 26 16:31:03 brian pppd[3840]: LCP: timeout sending Config-Requests
Aug 26 16:31:03 brian pppd[3840]: Connection terminated.
Aug 26 16:31:04 brian pppd[3840]: Exit.

If I issue 'pppd call provider' at servis' prompt I get the prompt back
immediately and in the log I only get:

Aug 26 19:03:16 brian pppd[3872]: pppd 2.3.5 started by servis, uid 6262

It never exits however. It has probably detached from the tty but no
logs show any activity.  I have to explicitly kill the pid.

If I issue 'pppd file /etc/ppp/peers/provider' then it seg faults!!!!!

% pppd file /etc/ppp/peers/provider
Segmentation fault

But a strace on the above won't even run!

% strace -f /usr/sbin/pppd file /etc/ppp/peers/provider
execve("/usr/sbin/pppd", ["/usr/sbin/pppd", "file", "/etc/ppp/peers/provider"], [/* 35 vars */]) = 0
strace: exec: Operation not permitted

I am about ready to give up! 

Thanks for all your help,
