So, what is the variable 'port' initialized to? It should be a const
char* with the name of a network service found in /etc/services or else
the string representation of a port number in decimal.
Failing that, this is almost certainly a configuration snafu on your
Does this machine have an entry for localhost in /etc/hosts ? Can it
resolve localhost via the DNS? Or through any other means such as NIS or
% getent hosts localhost
If that fails, sanity check /etc/nsswitch.conf and /etc/resolv.conf
