Module ip_gre.o not found (tryning to install VPN server)

Hello.

I'm trying to install a VPN server on my Slavkware 12.1 box that I use as a DLS router on my LAN.

I tried installing Poptop (http://www.poptop.org/) by following their README and I hope that this part went well.

Now when I try connecting to the VPN server (from windows), I get this error in the log:

pptpd[24143]: MGR: dropped slow initial connection
pptpd[24158]: GRE: read(fd=7,buffer=8050980,len=8260) from network failed: status = -1 error = Protocol not available

I think I'm missing ip_gre.o and I guess I should somehow compile this on my own. Can anybody give me a short step by step info on how to do this.

Or is the problem something else?

Thanks!

Or maybe I can just download ip_gre.o from somewhere?

All you have to do is type, as root:

Code:

modprobe ip_gre

The module is included in Slackware 12.2, guess it is in Slackware 12.1 too.
