[sudo-sys] omni now meshed via tunnel

When connecting to peoplesopen.net in omni you will now be able to talk to the rest of the mesh. Until we mount something on the roof this is happening via a tunnel. This also means that anything plugged into the correct switch in the server rack will get a mesh IP and be accessible by anyone on the mesh. If someone wants to set up mesh services it is now very easy. Be aware that the peoplesopen.net network at omni does not pipe internet-bound traffic through a VPN since we don't care about that added layer of protection at sudo room. I set up tunneldigger (which establishes l2tp tunnels) and babeld (mesh routing protocol) on room.sudoroom.org The startup script is in /etc/init.d/tunneldigger The hook script called once the tunnel is up is at /opt/mesh_tunnel/hook.sh -- marc/juul
