OK - just FYI, I got that command from http://lxc.sourceforge.net/network.php

Trying to use the "ip link set" command, I get a different problem - it
reports an RTNETLINK error:

 [root@C100273 iproute2-2.6.25]# ps aux | grep tcsh
 root     21918  0.0  0.0  71036  2084 pts/1    S+   16:47   0:00 -bin/tcsh
 root     22008  0.0  0.0  61144   716 pts/2    R+   16:57   0:00 grep tcsh
 [root@C100273 iproute2-2.6.25]# ip/ip link set eth4 netns 21918
 RTNETLINK answers: Invalid argument

Any idea what could cause that error?

Thanks,
Chris
