>Environment:
Pentium/133, 48MB RAM, USRobotics Sportster 33.6 internal PnP modem
>Description:
Using user PPP. After a random amount of time (5-20 minutes) the
session will
lock up. Packets are sent, but never received. ping shows lines like
the following (after being stopped with ctrl-c):
200 packets sent, 0 received, 100% loss
No networking program works. Netscape freezes up.
show modem in user PPP shows the "sent" bytes growing but the
"received"
stay the same.
Typing "close" to the user PPP program hangs-up. Typing "dial" redials
and everything again works, for another 5-20 minutes.
I contacted freebsd-stable about this: many people responded claiming
they had the same problem. For some it mysteriously went away, others
are still experiencing it. The consensus is that it is relatively new.
I have tried this with both the GENERIC kernel, and various kernel
compiles
I did, all with different options.
Have tried both PnP kernels, and non-PnP, after seeing a pattern on the
mailing list: many of the responders claimed they were using USR PnP
modems.
I haven't yet been able to reproduce it with the kernel pppd.
A bug with the tun0 driver?
