Hey List:

Need ya help please....

Im being attacked on port 3123 as you can see on my "Incoming" router = log.

66.135.143.20 3123
212.126.10.100 3123
24.160.119.181 3123
66.135.143.20 3123
212.126.10.100 3123
66.135.143.20 3123
24.160.119.181 3123
66.135.143.20 3123
217.217.49.108 3123
66.135.143.20 3123
24.31.216.77 3123
217.217.49.108 3123
66.135.143.20 3123
217.217.49.108 3123
66.135.143.20 3123

So I pick out one of the IP's and email the hostmaster about the attack, =
and this is his reply below. .. .. Hello,
   These 'attacks' are you running KaZaA. This IP is your KaZaA = supernode.
Please learn how to use and understand your firewall.

-nm
----------------------------------------------

I DONT RUN KAZAA!!!=20
WHY IS HE SAYING THIS CRAP!
My network is very very small, and its virus free and bot/trojan free.=20
Firewall/Router, and desktops have Firewalls.=20 Kazaa is nowhere
installed!! AND... that isnt the right port for a = supernode anyway!!!
----------------------------------------------

This is the letter I sent him..before his shitty reply.
