How to auto-ban access form certain IP addresses?

I run an RH9 box and someone is constantly trying to break in over the last year. Its not remotely accessible in they way they are trying so I am not concerned. However, I wish I would shut down access from a certain ip address after so many attempts, and send an email to myself. As opposed to watching 1000s of entries in my log each day from the same address.

Is there a manual way to do this? I assume by editing config files for telnet,ssh, etc. Is there an automatic way to do this?
