How to upgrade NMAP to the latest version

Backtrack 5 r3 already comes up with version 6.01 of nmap. A new version (6.25) has been released and it comes up with 85 new scripts, performance enhancement and a lot of other new features. Upgrading to the new version is not possible yet with the classical apt-get update & apt-get upgrade commands, but you have rather to download the new version from nmap's official website page and compile it yourself. First of all, hit the following link to download the new version: http://nmap.org/download.html

After that,go to the directory of the downloaded pack
(for example cd /root/Downloads) and issue the following commands:

#tar xvf nmap-6.25.tar.bz2

#cd nmap-6.25

#./configure

#make

#make install
