I have two Linux boxs. The primary one is connected to the Internet
via a full time dial up connection. The secondary box is in a remote
location connected to the primary via a full time dial up. The
secondary is routed through the primary and onto the Internet.
Everything works OK except with occasional PPP lockups between the
primary and secondary Linux boxs. The dial up connection is never
broken, it simply stops passing data in either direction. By this I
mean I can no longer ping between the two machines. Another thing that
is interesting is if I use the secondary machine and telnet to the
primary, the primary knows someone is attempting a telnet session but
refuses to serve it because it can't identify the remote IP address.
I am running with Slackware and a kernel of 2.0.30. All my connections
are run through inetd. The PPP lockups can sometimes be as close as
four hours apart to many days apart. I have checked the messages and
syslog files looking for errors but there are none.
