[pptp-server] ppp modprobe errors during install

[Brian L. DiMambro]

Hi All

I am having problems getting PoPToP installed on an Alpha DS10 running the 
generic 2.2.18 kernel. I have followed the HOWTO instructions and have 
successfully connected with no encryption. I then installed ppp with mppe 
using a clean distribution of the 22.18 kernel, ppp2.3.11 and the following 
patches:

ppp-2.3.11-openssl-0.9.5a-mppe-alpha.patch
ppp_mppe_compressed_data_fix.diff
if_ppp_2.2.17.diff

The if_ppp_2.2.17.diff patch would not install so I manually updated the 
/usr/src/linux/include/linux/if_ppp.h and  if_pppvar.h files to correct the 
compile time errors. The compile of ppp completed successfully even though 
I saw a message about an un-registered compressor when ppp.o was being 
compiled. I copied the files to /lib/modules/2.2.18/net, registered the new 
modules per the HOWTO and successfully completed the depmod -a. When I run 
the modprobe ppp I get the following errors:

[root at bubba src]# modprobe ppp

I also tried the non Alpha mppe patch with the same errors.

Any help will be greatly appreciated.

Thanks in advance
