I don't recall having any problems dialing out from my home linux box
to different places. Recently I added a dial-in capability, starting
mgetty on boot. More precisely, when there is an incoming call from a
particular place that logs in as a special user, pppd is started as
that user's shell, with a specific set of options (details below).
It works fine. However, when after this incoming call is successfully
completed and terminated, I cannot dial out. Only after I comment out
the mgetty stanza in /etc/inittab (that I took from the mgetty info
pages essentially), and reboot, does the dial-out succeed.
I am including the details that seem to me relevant - the setup and
the syslog of the unsuccessful dial-out attempt. If anyone has any
idea what I am missing here, I'll be very grateful.
