Bug 5663

I believe that this is a bug in pppd.  I have not yet isolated it.
This did not show up on my system until I upgrade to ppp-2.3.10
from ppp-2.3.9.  The cause of the problem is not apparant from
inspecting a diff between ppp-2.3.9 and ppp-2.3.10.

changed component

I was running ppp-2.3.7 before the upgrade from 6.0 -> 6.1, and the
upgrade caused the same problems for me. Ie, it dials, connects,
negotiates ppp & hangs up & redials & connects again.
The upgrade logs show nothing except that the ppp-2.3.7 docs were
unsucessfully removed.

I was having a slightly different problem with pppd. That is,
it successfully connected, DNS lookup and ping worked O.K., but
TCP connections would hang (most of the time).

Here's a possible clue: I notice that in the system log, the kernel
claims to be running PPP version 2.3.7, while the pppd is version
2.3.10. Perhaps the wrong PPP support was compiled into the kernel.
Anyway, reverting to pppd version 3.2.7 solved the problem for me.

Same problem on a RH6.1 installed from scratch, same ppp version
2.3.7 log. Once (actually no more investigations done) pppd
activated himself with wrong IP address for local side, assuming
the ethernet one. Obviously no routing possible...
[P.S.: sorry, I don't speak english...]

I have the very same problem since upgrading from RH5.2 to RH6.1

Please try
ftp://people.redhat.com/johnsonm/ppp-2.3.10-3.i386.rpm
and see if it fixes this problem for you.

I have been testing ppp-2.3.10-3 for the last two days and it seems
to fix the problem completely for me.

ppp-2.3.10-3 is now working for me as well. Thanks.

Thanks y'all for testing!  The -3 release that went out as an
official errata item is the same package that I made available
for you, so no need to download the new package.
