Really? That's great..  I have to do the same for my Thesis, but I'm kind
of lost using preprocessors in snort.

I've heard that, but how can I port those algorithms to my snort.?
i've tried modifying some files and adding the .C and .H files on snort

how can I patch my snort? I'm Working on Ubuntu and CentOS

Awesome! hope you finish it completely and publish it. :-)

Actually, I use my Computer Science Lab of My college for checking the
traffic with snort
but I just check them with signatures, I want to check it with anomalies
and statistics too,
that's why I'm asking a lot for those things, hehe :-D

Thanks Again, Hope you can help me again.
