Re: Weird Traffic

["Jonathan Adams" <keirre.adams () gmail com>]

I've not found the source of the majority of the data, but I have
found a huge amount of weird requests in my apache log, and I'm fairly
certain its http traffic...  I may cron of a protocol analysis tool
tonite to see if I can find more. I've run nmap scans, but stupidly
have not used the udp scan as someone else posted... nothing amiss in
the process list...

Theres no changes to my httpd.conf, and I dont see a big hit in my
disk space... dunno... it is a mystery.  I'll do some more analysis
and if I find anything Ill post it to the list
