[Snort-users] ICMP Source Quench

Of course...but I did my search on yahoo and the results were so noisy that
I couldn't find anything specific on the topic. Also...I would have thought
that Snort would have had at least a blurb in the online rule docs...since
they didn't and the yahoo results were so bad, i didn't push it figuring it
was something rather esoteric.

Please tell me you atleast did (Lie if you have to :-)):
The additional $0.02 from experience:
Often times if you see ICMP source quenches your network is either
flooding a particular network OR you netblock is being spoofed and
some poor old sod is being flooded and can only yell at you about it.
Try reverse dns on the Source IP and if it's an IRC server, it's probably
