If you follow this blog, you know that I did an article on the first stable release of Namp http://www.pccybertek.com/2010/01/nmap-5-20-released yesterday. Now that it has been out for a week, Fydor has already released another update, Namp 5.21 which is also a stable
release and not a beta. It’s mainly just a bug fix release. So I have updated the download section here with a link to the 5.21 release, which is on the right column about 3/4 of the way down the page. My download link is directly to the file on the insecure.org website or you can go to the Nmap download page yourself.

But I don’t want to just tell you about the update, I’d like to offer you some more since you took the time to stop by here. So here is a link to Iron Geek’s Baisc Nmap Tutorial video. And if already know the basics and would like to move on to some more advanced lesson, here is Iron Geek’s Nmap Video Tutorial 2: Port Scan Boogaloo Happy port knocking.
