PPP Failing - Unsupported Protocol

[Kenneth Jacker <khj@be.cs.appstate.edu>]

[ sarge, kernel 2.4.26-1-686 ]

Well, I finally got my PPP link to "work" from home to office.

Unfortunately, however, after awhile things come to a halt when trying
to transfer (e.g., with 'scp', or 'firefox') a large number of bytes
(e.g., multiple 50k files in a row or installing a new 'firefox'
theme).  I must reestablish the PPP connection to (temporarily) regain
network access.

Here's what I see in "syslog":

BTW, this is working fine in my previous RH9 system (on 2nd harddrive).


I sure hope someone can help with *this* problem!

Thanks,
