I've been experiencing poor PPP performance for a while now (it's always
been bad --line noise, I think-- so I wasn't sure if it has actually
gotten worse with the last dozen or so kernels or if it was my
imagination), including frequently dropped connections; but tonight I
had a new experience: the link 'froze' in the middle of a POP mail
transfer to my ISP. I've appended /var/log/messages output to this
note. 'dip -k' and then 'kill'ing the pppd PID didn't resolve
things. I then -HUP'ed inetd and pppd, after which I could re-establish
the link. I only reconnected once despite the duplicated IP address
negotiation messages at the end of the /var/log/messages transcript; is
this normal? Incidentally, my ISP is using OSF/1 on a DEC Alpha.
Whoa! More weirdness! I just checked my outgoing mail logs for the entry
that I was in the midst of sending when PPP failed. There are three
complete and identical entries for this message. They are time-stamped
23:32:51, 23:34:03, and 23:44:47. The last of these is from after I
re-established my connection to my ISP and re-sent the message. I only
tried to send the message once before that.
Kernel: pre2.0.7
ppp: 2.2.0f
modules: 1.3.69f
kerneld: running, but I insmod'ed slhc, ppp, and bsd_comp by hand
