[uml-user] Networkin Problems

[jformann <jfo...@mu...>]

Hi,

I'm trying to get UML runnig on a Redhat 7.1 (IIRC) with a 2.4.2-2 Kernel.
Everything works fine, till I tryed to get network support.

If I use tuntab (linux con=pty con0=fd:0,fd:1 ubd0=cow1,root_fs 
eth0=tuntap,,,192.168.42.77)
This error occours:usermode:~# ifconfig eth0 192.168.42.246 up
tuntap_open_tramp : didn't receive a message
* insmod tun
insmod: a module named tun already exists
Using /lib/modules/2.4.2-2/kernel/drivers/net/tun.o
TUNSETIFF : Invalid argument
tuntap_open_tramp failed - errno = 22
SIOCSIFFLAGS: Invalid argument
tuntap_open_tramp : didn't receive a message
* insmod tun
insmod: a module named tun already exists
Using /lib/modules/2.4.2-2/kernel/drivers/net/tun.o
TUNSETIFF : Invalid argument
tuntap_open_tramp failed - errno = 22
SIOCSIFFLAGS: Invalid argument

And if I use ethertab

usermode:~# ifconfig eth0 192.168.42.250 up
etap_tramp : read of status failed, errno = 0
Child 26940 exited with signal 11
etap_tramp failed - errno = 22
SIOCSIFFLAGS: Invalid argument
etap_tramp : read of status failed, errno = 0
Child 26941 exited with signal 11
etap_tramp failed - errno = 22
SIOCSIFFLAGS: Invalid argument

ifconfig -a  always shows eth0

Can you help me?

Is there an known Bug (in the kernel, in UML, in the debian root_fs or 
somewhere else)?
