[Vtun-Users] questions/faq didn't help (File descriptor in bad state)

[<sl...@mo...>]

I'm trying to network two machines with vtund, they both have the Universal
Tun Driver. Vtund works fine on the machine linux, with the 2.2.20 kernel.
Both machinse have identical /dev/tun*, /dev/tap* inodes. Both machines have
/dev/net/tun identical also. I am using the default driver (seeing how the
one provided by vtun.sourceforge.net didn't compile on 2.4.14) provided by
the kernel.
