genlist – Backtrack – Miscellaneous – Miscellaneous Network – genlist

Clicking on the genlist menu item in Backtrack Linux opens a terminal window and outputs the genlist help menu at the top. Genlist is a Perl script written to provide an easy way to generate a list of live hosts on a network or set of networks so you can then begin analyzing those hosts. All the genlist Perl script does is call nmap with the -sP switch and parse the results so only the live IP addresses are output and as simple as it seems its a handy little tool if you do penetration testing on a regular basis. Below we describe genlist in more detail and show an example of genlist in action.
