Re: how to block ALL AIM traffic ?

HI,

I don't have AIM traffic on my network right now... but what I would do it
conduct a tcpdump, full packet capture (-s 0) for port 5190 traffic.  Then
I would inspect the payload for a pattern.  Once I have a pattern write a
filter/signature based on it to conduct the packet drop.

I was hoping to give you a signature or pattern, but we seem to be AIM
free here.
