[pptp-server] Linux > 2.4.8 ?

[Sarel Botha]

Oops, originally sent this only to Don...

Aren't these just security-related patches?
I think my problem might be something else then. When I try to make the VPN
connection I get "GRE: Protocol not available".
Here is the log.

I have pptp-1.0.1 and ppp-2.4.1 running on linux-2.4.13.  The only problem
that I encountered was that I had to patch by hand to get the ppp_mppe.o
module.  I started with the patch for 2.4.4 found here:
http://www.advancevpn.com/public/linux-2.4.4-openssl-0.9.6a-mppe.patch.gz.
This site also has patches for ppp-2.4.1 (look in
http://www.advancevpn.com/public).

Anyone gotten pptpd running a kernel later than 2.4.8?

There are security problems with earlier kernels and the linux ACLs patch
only work on the very latest.

Thanks
