[TriLUG] Iptables question

[Mark Fowle]

Is there a way to setup a rule that says, if I can more than X number of 
failed attempts from an inbound IP, to have the system set up a rule 
that will block that IP?

IE: if 62.45.93.116 makes more that 3 attempts - the system will block 
62.45.93.0/0 from reaching the system?

Thanks,
Mark
