QEMU and networking

[Steven Heimann]

Has anyone had any success getting tun0 networking working with Ubuntu
5.10 and QEMU.

I have compiled QEMU from source because I wanted Win2k which needs a
flag not available on the standard Ubuntu version (-win2k-hack).  I have
installed uml-utilities which was was needed to configure the tun0
device.  I have configured tun0 chmod 666 so it would be writable.

I have (after much stuffing around) managed to get a device tun0 on my
host with ip 192.168.12.2 and an ethernet ip of 192.168.12.3 on the
Win2k guest.

However, they will not talk to each other.  I can not ping the host from
the guest or vica versa.

I need to use tun type networking because I need a particular program on
the guest to be able to talk to the rest of the network.  This program
is not using http/port 80 so I can not use user-net.

Any suggestions?
