[pptp-server] pptpd 1.0.1 + pppd 2.4.0/1 Error 650

[Jonas Frey]

Hi there,

i looked deeply into the archieves but was unable to find this issue
solved.
Heres the prob:
I have a machine running poptop with pppd 2.4.0 and pppd 2.4.1 (both
dont work). I patched both to do mschap/mppe etc.
I am running kernel 2.4.4 with the ip_gre and ppp_mppe modules.
Clientside: Win98SE with 40bit encryption fix, also a linux box.

When i connect to poptop with either the linux or the windows client the
logs display this:

Same Problem with pppd 2.4.0.



My config is as follows:

pptp.conf:

debug                           #This can be removed when things are 
option /etc/ppp/options1
localip  192.168.1.80-89        #look in the /etc/pptpd.conf file 
remoteip 192.168.1.70-79    

options1:

lock
debug
auth
proxyarp
+chap
+chapms
+chapms-v2
mppe-40
mppe-128
mppe-stateless

chap-secrets:

# Secrets for authentication using CHAP
# client        server  secret                  IP addresses
testing         server  123     *


I also tried without encryption, it doesnt matter, same logs.
The Client sides gives a 650 on windows and a

on linux.


Does anyone know howto fix this and/or has any suggestions?

Thanks,
