[plug] Zerotier and Ubuntu 18.04

[Shanon Loughton]

Hi

Im trying to just join a friends network on zerotier with Ubuntu 18.04.
Anyone know how to get the TUN device working? It seems to be there. I just
cant get a zt0 interface. Router is forwarding 9993, and other UPNP
zerotier connections are active. See PORT_ERROR.

Thanks for any help.
