I couldn't get vtund to work with 2.6 at all. Error in /var/log/messages said unable to load tun device. I found a broken link in my /dev, and then found the exact solution in the debian mailing lists. http://lists.debian.org/debian-user-danish/2003/09/msg00027.html The solution is to add this block to the /etc/devfsd.conf: # Create compatibility link for broken misc/net/tun driver (must uncomment the # MKOLDCOMPAT for misc above if you want to use this) REGISTER ^misc/net/tun$ CFUNCTION GLOBAL unlink net/tun REGISTER ^misc/net/tun$ CFUNCTION GLOBAL symlink /dev/$devname net/tun
devfsd bug, not a kernel bug.
btw... MKOLDCOMPAT is already turned on in our devfsd.conf
added to cvs, sorry for the delay !
