Building Unicornscan in Kali Linux 1.0

Image may be NSFW.
Clik here to view.

Unicornscan is no longer packaged with Kali Linux 1.0. One of my scripts (onetwopunch.sh) happens to use it, so I went about building Unicornscan from source. I ran into a couple of snags when building it, but I've documented it here to make things easier for others.

Unicornscan requires flex which isn't installed in Kali Linux 1.0, so install it:

root@kali# apt-get install flex

This should install smoothly, and once it's, download the latest version of Unicornscan from http://www.unicornscan.org/. Unpack it and build as follows:

root@kali# ./configure CFLAGS=-D_GNU_SOURCE && make && make install

Once it's done, you'll find unicornscan in /usr/local/bin
