This should be part of the base/extended print system.  Barring that,
here is a recent copy for the mailing list archives.

iWell, it came originally from a sample whois program
in the Comer "internetworking with TCP/IP," though, as far
as I know, that isn't a problem, at least if you don't want
to sell it.  If you are really worried, or want a good book
(highly recommended by everyone) then buy one.

Hope it works for you.
