I haven't been playing with any other snort variants lately after tinkering with snort clamAV. It's time to actually make a move to try out interesting stuff. I have heard about snort spade that used to detect anomaly traffics based on statiscal analysis a while ago, this project was revived and under active development currently. Another interesting project that inspired by snort is the one that adding preprocessor to detect the portscan using AI(neural), one of my friend is actually researching on Worm detection using neural network design so that might be helpful for his research work. You may find these two projects at

After downloading the source through CVS, I just run sh autojunk.sh, usual configure, make and make install, it is installed fine. The only part I have tweak when configure is adding the prefix such as when I compiled snort-spade, I run
And for snort-AI
And lastly snort-2.6 Beta
