I was curious if anyone might know what would cause ppp to hang after working
"successfully" for about a minute or two.

I had ppp working fine between two Sun IPCs using telebet t1000 modems at 9600.
I then install ppp on an SLC to take home. The installation seemed to work ok,
however after I establish a valid (or what I think is valid) ppp connection,
a minute or two later, everything hangs (from a ppp point of view).

I enabled the kernel messages. Here they are:

The remote machine doing the dialing is "zak". The machine in the office is
"paris". The last two ppp messages are from when I killed ppp on "zak".

As can be seen from the log, I did successfully log into paris from zak, but 
there seem to be lots of protocol errors, then at 10:47 there are no
messages until I kill the session.

Is there anything obvious I might be doing wrong that causes the session to 
"hang"?



Thanks,


Brian
