[Difx-users] WARNING Could not open monitoring socket

[Adam Deller]

What network interfaces do you have on these machines?  When running only
on one machine, it is probably using loopback and not the network interface
at all, and then maybe when you try with two machines it discovers it can't
use the external network interface.  What does ifconfig say?

Cheers,
Adam
