WHOIS free server

Hi guys,

does anyone know a free _whois_server_ to run on a linux box?
I looked for it on google but maybe I did a bad research.

Or is it not so useful for private use that no one developed it?

TIA,

Alex.

Essentially it's a program that accepts one or more words as a single
line of input and returns a corresponding chunk of text.

Using something like inetd (or xinetd) to manage the network socket
connections allows you to write a lightweigt whois server even in
shell script.

In inetd.conf:
whois stream tcp nowait nobody /usr/local/bin/whois-server ws

In the executable file /usr/local/bin/whois-server:
#!/bin/sh
#
if test 0 -eq $#
then
IFS= read LINE # Read from socket via inetd
else
LINE="$1" # Allows for 'whois-server <key>'
fi

# File corresponding to <key> is in /usr/local/whois-data/. Note
# that non-alphanumeric characters are stripped from the key
#
KEY=`echo "$LINE" | tr -cd '[:alnum:]'`
FILE="/usr/local/whois-data/$KEY"

if test -s "$FILE"
then
# Return the data corresponding to key back to the caller
#
cat "$FILE"
else
# File not found (or is zero length)
#
echo "Cannot find any matching record for << $KEY >>"
fi
exit 0

Once you define your requirements criteria (e.g. number of requests per
second, complexity of input parsing, size of lookup database) you can
decide how complex a solution you require.

You can find source code at <http://www.ripe.net/tools>, but why would
you need a private whois server anyway?

Essentially whois is a service that provides, from my point of view, information about which network
an host belongs to. So when in our company we get in trouble we easily want to know who is that is
sending SPAM or viruses or whatever.
I agree that an spreadsheet can do the same thing but as we set up a DNS for internal use we thought
we could use such a tool like whois to solve the problem I spoke above.
Because of many programs available that are able to query WHOIS server we hopefully would use them
against our own whois server.

Thanks,

Alex.

Yes, which network. But of course that is provided in your company by the
network IP You surely do not have so many networks that you cannot keep
thyem straight?

>sending SPAM or viruses or whatever.

Whois will not tell you It will just tell you the network the system is on.

If you roll your own server it can tell you whatever you want it to.
Pretty much like "finger", really.

Are you sure you're not looking for something like "dig -x"? Whois is
typically used to identify the owner of a network (or a domain, but that
seems not to be your area of interest).

In your case, you'd be the owner. Especially since you mentioned "host",
I'm thinking that perhaps all you want is to map from IP to hostname.
Dig does that with the -x option.

Dig is not available on all OS and unfortunately not all members of our administration group use Linux/Unix :-(

Thank you

The older "nslookup" exists on (at least) unix/linux and windows
platforms.

nslookup <name_or_ip>

Not sure if this is what you want, but 1st hit on googly using;
"Debian Linux whois server" as keywords...
