Is there an advantage to this over using /etc/hosts.allow and 
/etc/hosts.deny.

I setup a hosts.allows with sshd: localip blocks and the hosts.deny 
with sshd:ALL.

On our campus with have 4 Class C IP block, and I include my 
home machines IP,  so I can access it from there, and now attempts 
just show as refused, instead of the bad passwords.

Michael

Thanks again for the pointer to denyhosts.
Great program, although the fedora extras version is something like 0.6.0 I
tested it with this version.
I was so impressed with the program I removed the 0.6.0 version and then
downloaded the latest 1.0.1-1 and compiled it.

Thanks again !!!
