Suffering attack seems to be a way of life now Michael.

Seems like anything I present gets hit: telnet, ssh, http, ...  My wiki 
even had a few successful spam submissions when security was open.
I like DenyHosts a lot.  A low X means a few of my friends get to ask 
for me to re-open their stuff, but that is pretty low price to rest 
easily at night.  It seems to me I get fewer attempts when I change 
service ports around -- for example ssh moved from 22 to 4567.  It may 
not last, but the quiet is nice now.

Good luck and keep reading Linux Journal Paranoid Penguin column.
