The nameserver has a well known port number, 53.  Any nameserver uses that
port.  The resolver tends to use udp on all queries, unless they are
truncated, and doesn't open any connections.

The problem with ypserv as shipped on the patch tape, is that it waits
only 8 seconds for a reply from the named, if it dies, it takes longer
than 8 seconds to find out.
