Re: [Qemu-devel] eth0 problems

[Lonnie Cumberland <lonnie@neenet.com>]

Hello All,

I just looked at  the kernel sources for my 2.6.3-7mdk kernel and 
TUN/TAP has already been compiled in as a module.

Although there is no /dev/net/tun0 listed or /dev/tun0 as well

Actually, on I do not even see the /dev/eth0 even though it is now 
working on my  cable modem and the ifconfig show that it is there.

Any other ideas?

Thanks for the help,
Lonnie
