Using the stock whois (on Fedora) I can easily get information for an IP adress:
$ whois SOME_IP
% This is the RIPE Database query service.
% The objects are in RPSL format.
%
% The RIPE Database is subject to Terms and Conditions.
[..]
% Information related to 'SOME_IP/SOME_AS'
route: SOME_ROUTE
mnt-by: SOME_STRING
[..]
Now I want to inverse lookup entries that have the SOME_STRING in 'mnt-by'.
I've done that successfully via the RIPE web interface.
But how to do that via the command line?
(e.g. for easier post-processing/scripting)
RIPE documents the -i option, but:
$ whois.md -h riswhois.ripe.net -i mnt-by SOME_STRING
Warning: RIPE flags used with a traditional server.
[just options listing without -i]
$ jwhois -h riswhois.ripe.net -i mnt-by SOME_STRING
[Querying riswhois.ripe.net]
[riswhois.ripe.net]

% IPv4 or IPv6 address to origin prefix match

Am I supposed to use another whois client for such queries?
