[pptp-server] PoPToP and SMP?

[Michael Walter]

I don't know if this helps, but we are currently running Poptop on a
multi-processor capable dell poweredge 1300 with multi-processor kernel
2.2.16(from kernel.org).  Poptop version is 1.0.0 and pppd-2.3.11.  Patches
included are the patch to strip the domain name, and the patch to force
encryption.  The system supports around 10 concurrent vpn sessions as well
as the internet traffic for 100 users.  We only run a single processor in
the machine, but everything is set up for a dual processor system, we have
had none of the problems below and have been online with various versions of
poptop for a little over a year and a half.

Thanks,

Michael J. Walter

Has anyone succeeded in getting PoPToP to run on a dual processor system?  I
ask because I've got two systems that I need to have VPN access to (from
Linux and Windows machines).  I've installed PoPToP on a single processor
system and it's running perfectly.  However, following the same steps on the
dual processor system I get the following in my logs when trying to connect.
