Gibs auf, cipe is tot seit Mitte 2002. Gemäß deiner Homepage sollte man 
auch besser die Finger von cipe lassen, hat Security Probelme by design, 
es sollte nicht mehr genutzt werden. Grüße nach Bayern aus Württemberg! 
(ab jetzt auf englisch:)

The Problem with cipe is that the developer themself gave up the project 
since cipe has no real reason to continue, OpenVPN is more simple in 
config, uses existing kernel modules (tun/tap modules), and the link is 
more reliable. On top of that OpenVPN does not have "by design" 
weaknesses like the cipe protocol has. OpenVPN uses some parts of 
cipe-win for its Windows driver code stuff.
Check http://openvpn.net/static.html the config is sooo simple, I just 
suggest to add the line 'cipher AES-256-CBC'. Server and client side 
linux/windows mix is no problem, even mac osx clients exist.

You are free to continue developing cipe to work with the latest 2.4 and 
2.6 kernels if you want to, cipe is somewhat dead since last code update 
was January 2002 (see http://sites.inka.de/bigred/devel/cipe.html and  
http://sourceforge.net/project/showfiles.php?group_id=66201 ).

The most common OpenVPN start problems are: forgotten tun/tap kernel 
modules in kernel (no prob in debian and other newer distros, just 
modprobe tun) and missing /dev/net/tun device. For the latter mkdir 
/dev/net and mknod /dev/net/tun c 10 200 should be sufficient (needed 
for the six years old RedHat Linux 7.1 as example).

IMHO Olaf Titz should give some big notes on the cipe homepage and the 
sourceforge-dl page that cipe will not be continued by him, since this 
mailing list ONLY wakes up due to allways the same reason, cipe in newer 
kernels/distros.

kind regards,
