This is just what is monitored with my Prelude Intrusion Detection System.
My SNORT logs are immense. I am just Joe Blow to the world so you can guess who is knocking on YOUR doors too. If you have your filtering rules set just right...no one should be able to 'ice' it and you DONT want to find out. Trust me .asm, someone is scanning your subnet right now examining all the addresses in your block. I get scans for open ftp, telnet and sql ports EVERYDAY.
