Hi John, Even I am facing similar issue, container throws this error: ubuntu@root-local-machine-2:~$ iptables -L FATAL: Could not load /lib/modules/3.11.0-12-generic/modules.dep: No such file or directory iptables v1.4.12: can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.
It'll be great if you can share what changes you made in init scripts.

Is there a cgroup I should include > for sharing iptables modules? Kernel modules aren't loaded per-container but globally for the whole host. It's not recommended (and usually blocked by either dropping the capability or by having apparmor prevent it) to load modules from within a container. Instead you should make sure all your kernel modules are loaded from the host before you start your containers. I suspect the difference between your server and your colleague's is that he has some init scripts or something else calling iptables before he starts his containers which will load any modules required by his container. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org<mailto:lxc-users@lists.linuxcontainers.org> http://lists.linuxcontainers.org/listinfo/lxc-users -- John Baker Network Administrator Marlboro College Phone: 451-7551 Cell: 490-0066
