the ports < 1024 are well known ports, so if progsoc use them then it is
extremely likely that every other unix box in the world will use them. For
example the well known port for http is 80, this means that your netscape
defaults to connecting to a host on port 80. The only real way to find out
if a port exists on a remote machine (it might be disabled if there isn't
a web server running for example) is to try and connect to that port,
either with a specific application or just good old telnet.
