Hi guys, i have a log file that normally is many many many IP's in it.
However sometimes i get attacked by a single IP and it slows down the system. The log file shows this IP more than any other.

What i was thinking of was a script that could check teh file, if it has shed loads of the same IP it woudl do something ( mail me ) i can do the mail part, but the actual looking and working with part im stuck on.

Has anyone got any idea how to do the below?

Check file.log to see if an IP is repeated lets say 1000 times or more.
If so then do Blaaaaa. Else do nothing.

I cant get it to look for an IP ie 1.1.1.1 as it changes, so somehow it will need to be able to identify what it looks like?

Any info would be GReeeeeaaaat.
