Well, not directly, but i found a work-around. After speaking with
Paul Mackerras (pppd maintainer) days worth of debugging [well, i
spare the rest of the pain] seems that Linux 2.2 kernel ppp driver
sucks. Plain and simple. Right now i'm using that same setup (PPP over
SSH running over a 100 Mbps Eth) but the server side of the connection
is now a _fast_ dual Ultra60/Solaris8 machine. The Solaris is running
same PPP version (pppd-2.3.11) as the client side (Linux, 2.2.15) but
with the Solaris kernel drivers supplied w/ pppd-2.3.11 as modules. Why this
works like a heavenly bliss and using Linux as a server
sucks...Well...i don't care anymore :)
In the plans was to try one of the 2.3 kernels, see if bundled PPP
driver is any better. Needless to say, it never happened. Also, i was
planning to try sparc-linux on the same hardware to really
pinpoint the PPP kernel driver as the source of troubles. (I've tried
sparc-linux on the server side but on a slower dual-SS20 and the
same suckage happened, but there you might blame hardw. performance).
All in all, what i would do is try a 2.3. kernel / latest-greatest
PPP kernel driver on some fast machine (in case you really intend to
push it _hard_ ;) ) . Not much hope, but still, might worth a shot.
If you have any results/experience with that, i will be glad to hear
from you.
Hope this helps (somehow),

P.S: I Cc: this into linux-kernel noise, maybe someone will pick up
the issue - despite the total lack of any analysis/anatomy of the
claimed PPP kernel driver problem...>)
