I am trying to set up an openvpn server inside a lxc guest. However, it seams there is no tun device available in the container.
Starting openvpn inside the container gives me this error:
Tue Sep 18 13:04:18 2012 Note: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2) Tue Sep 18 13:04:18 2012 do_ifconfig, tt->ipv6=0, tt->did_ifconfig_ipv6_setup=0 Tue Sep 18 13:04:18 2012 /sbin/ifconfig 10.6.0.1 pointopoint 10.6.0.2 mtu 1500 SIOCSIFADDR: No such device : ERROR while getting interface flags: No such device SIOCSIFDSTADDR: No such device : ERROR while getting interface flags: No such device SIOCSIFMTU: No such device Tue Sep 18 13:04:18 2012 Linux ifconfig failed: external program exited with error status: 1 Tue Sep 18 13:04:18 2012 Exiting
In my containers config, I see the following:
#tun lxc.cgroup.devices.allow = c 10:200 rwm
I'd assume this enabled tun devices for the container, but modprobe tun gives me another error:
FATAL: Could not load /lib/modules/3.2.0-30-generic/modules.dep: No such file or directory
I'm assuming I am missing some permission or something in my container. Can someone tell me what it is?
