SOLVED: stalling ppp
I think I have a solution that might work. I went back and renamed the
/lib/modules/2.2.19/net/bsd_comp.o module to
/lib/modules/2.2.19/net/bsd_comp.o.orig and rebooted. Concentric worked
fine after that. Looks like a problem in the module. I didn't see any
mention about it in bug track, but don't know if this should be reported as
a bug or not. The post I saw also wondered why so few people are seeing
this problem. Could it be because Concentric.net uses this compression
module and most others don't?

Thanks.

I've experienced exactly the same problem, but couldnt figure out how to
fix
it either. To add insult to the injury I have to say that when I boot
windoze
on my computer, connections with both ISPs work flawlessly. It seems like
windoze somehow reinitiates data transfer when flow control fails, while
ppp
(or modem, or whatever is responsible for the flow control) under linux
does
nothing and the transfer simply stalls. If somebody can help us with this I
would greatly appreciate it. Below are two logs, first one for the smooth
connection, and second for the erratic one.
Cheers,
