Good points James...you missed one though... port 22. I see more attempts on
SSH than any other port....stupid and LAME attempts but more on this than
any other...

Yes, I missed that in the logs. They are so few attempts, I only got 2
during the one day I sampled. Of course, when they can connect, they
try several names.
I also left off ports: 55838, 1026, 1027, 4899, 1334, 1025,. 6129...
If anyone is interested, I can send a copy of the report or even the log
file information.
Thanks,
