Interesting stuff:

a script to be called from tcpwrappers to allow / deny based on a query to a DNSBL

fail2ban-dronebl -- modified Monday, 18th August, 2008

a set of scripts to have fail2ban automatically submit brute-force attackers to DroneBL's DNSBL database. An RPCkey is needed. See the README file included in the archive for details.

droneblupd -- modified Sunday, 10th February, 2008

That is all.
