Not much

Become interested in sniffering recently, having so much fun with hacking my machines around, I am pretty impressed about what ettercap capability, it gives pretty good result when combining with other tools. I will write up a detail tutorial over this topic.

Also I learned some new OS fingerprinting techniques when I reviewed nmap,xprobe and ettercap fingerprinting code. I should come up some new discoveries as time goes on...hopefully!
