Is there a generally available program to provide the server function for
the whois program? The whois program by default connects to nic.ddn.mil,
however, makes provision to connect to the whois port (TCP port 43) of any
host specified by the -h argument. There are apparently a fair number of
sites other than nic.ddn.mil providing this service. My question is
whether there is a standard program available which one can plug into port
43 to answer whois questions or does each site typically write its own.
The whois program itself from ftp.uu.net is remarkably small and the code
very simple. Connect to port, write the command arguments to the port and
print to stdout anything that comes back from the port or issue some simple
error messages. I presume that RFC 812 fully describes the protocol, however,
I haven't seen that document yet.
I would rather not write this program if one already exists and is freely
available, however, looking (at a guess) for "whoisd" in archie found only
a single occurrance and that was for an executable at a site in finland.
I'm not really sure if this does what I'm looking for and I'd really rather
have source :-)
Thank-you for your trouble...
