Re: Some new SSH exploit script?

All,

Similarly, I have a large number of hacktards trying to login as root on
my servers.

I also have no need for apnic space to talk to my servers, most of my
legitimate requests come from the US.

As such, I have a script that I wrote that I call killapnic, that goes
out to the web, retrieves the apnic space and ipfw's all of it.

I have had great success with this. While it doesn't stop the local
hackers, it does stop 95% of the cruft that comes my way.

I suppose if I could adapt my script to do both this, and nailing out 3
bad attempts from x ip. This seems trivial.
