I was getting this exact behavior when I attempted to sup from the terminal
room at USENIX.  It turned out that the gethost() routing in scm.c assumes
that the hostname can be looked up with gethostbyname().  My hostname
is "voyager" but the ip was set to dhcp211.conference.usenix.org and
/etc/hosts only contained localhost.

I "fixed" this by making an entry for voyager in /etc/hosts that pointed
to the ip assigned by dhcp.

Does anyone know why sup cares what the hostname is anyway?
