On a host node I didn't need CAP_NET_ADMIN when starting it as root
(ie. maybe on my system root already has that cap by default; would make sense).

But on a VPS on the same host node I couldn't get it working yet.
It always gives errno=111 (ECONNREFUSED; "Connection refused").

Does yours work in a virtual machine, ie. on a VPS ?
