iceccd doesn't seem to obey --interface option #538

Hello,

I'm running iceccs on a cluster where each machine is a member of the same public net, and a private net.

I'm trying to force iceccd to only look for private network for listening to scheduler server broadcasts, but it still tries to use interface connecting to a public net.
