[pptp-server] pptpd & kernel 2.4.16

Hi Kai,

You should check if you have ip_gre.o build with your kernel.
And when it's a module, that it is loaded.

If you have to rebuild your kernel, I suggest upgrading to 2.4.18.
The linux-2.4.16-openssl-0.9.6b-mppe.patch will work ...

Regards,

David van Vyfeyken

Hello,

i use the following:

Kernel 2.4.16 
with linux-2.4.16-openssl-0.9.6b-mppe.patch)

pppd 2.4.1
with ppp-2.4.1-MSCHAPv2-fix.patch and ppp-2.4.1-openssl-0.9.6-mppe-patch
and require-mppe.diff

PoPToP v1.1.2

Before i install 2.4.16 i use 2.4.10 (this works fine). After upgrading
i get the following messages in our logfile:

Is this a know 'bug' ? If so, have i to downgrade to 2.4.10 or better
upgrade to 2.4.18 (if it works with pptpd) ?

Thanks for your help!

Best regards,
  Kai.
