PPTP wont encrypt
« on: June 25, 2002, 09:44:00 PM »
I know vpn has been covered over and over but I really can't find info on this problem in the newsgroup:
Connecting to e-smith with pptp from my windows box with encryption enabled won't work. If I disabled required encryption in the windows vpn client, the connection works fine (but un-encrypted of course wich is pointless for vpn.)
Can anyone help ?
Here's a copy of the messages logfile ::

e-smith PPTP server only supports 128 bits encryption. If you're using win2k, ME or 98, you'll have to apply a microsoft update to support 128 bits encryption (Sorry, I can't give you an URL to get this update).

does not encrypt or does not compress (from what I saw on your report)?? first try to disable compresion on your client before turning off encryption!! that could be a problem too!!

Compression is off.
And my options.pptp includes nodeflate anyways.
Devil Linux also forces 128bit and it works perfectly as my current vpn server.
This is the last barrier preventing me to switch to e-smith as my main server :-(
What puzzles me most is that "modprobe: Can't locate module char-major-108" line in the log file ! What is that module ?
