[Lxc-users] [lxc-users] - move ppp on container

[n.hicher]

I have already try this solution, it doesn't work :

root at server:~# lxc-ps --lxc
CONTAINER    PID TTY          TIME CMD
host1      23479 pts/5    00:00:00 lxc-init
host1      23481 pts/5    00:00:00 bash

root at server:~# ip link set ppp0 netns 23481
RTNETLINK answers: Invalid argument

root at server:~# ip link set ppp0 netns 23479
RTNETLINK answers: Invalid argument

Thanks
