Sorry about the earlier question, that was more or less just blank....
About a week ago I started noticing 3,000 or more requests coming from
several ips for the following DNS queries:
Those are just two examples, but each IP - I have about 20 of them now
create 3,000 or more queries within several minutes. All the queries are
exactly the same for ./ANY/ANY.....any idea what those queries are? or what
they are trying to do?
Also how can I create an 'ipfw' rule to block an ip if XX amount of
connections come in within XX amount of minutes/seconds?? Right now I
manually block them, and yes those IP's try a day or so later to DNS bomb
(?) my machine.
