[pptp-server] ppp-mppe under 2.4.x, continued

[C. Thomas]

Thanks to Santuu and robert for posting those
mini-howtos on ppp-mppe under kernel 2.4.x -

I have run across an interesting little problem after
following the instructions set down in those guides.

Let me give a little background into my setup:

I'm running a patched ppp-2.3.8 under kernel 2.2.18 as
the server.  I am trying to get my client at home, a
ppp-2.4.0 + 2.4.2 kernel debian machine to talk to it.

The ppp connection sets up as advertised, and the
server's log indicates mppe 128bit is set up, as well
as stateless compression.

However, when I ping the remote LAN from my client at
home, this appears in /var/log/syslog on the client
machine:

Feb 25 14:25:38 next pppd[1485]: rcvd [Compressed
data] 10 50 c0 ef e8 93 17 ab ...
Feb 25 14:25:41 next pppd[1485]: rcvd [Compressed
data] 10 51 26 a5 de ce 96 8a ...
Feb 25 14:25:47 next pppd[1485]: rcvd [Compressed
data] 10 52 76 8a 15 82 7a 29 ...
 
/var/log/pptpd.log on the server does not give any
indication that anything is wrong.

I should mention that Microsoft VPN clients have no
problem connecting to this server - and I have set up
a linux VPN client with it using a 2.2.18 kernel.  

Is there any known incompatibility between ppp-mppe
2.3.8 and 2.4.0?

Thanks,

C. Thomas
