This post on how to install the LLTD is largely ripped off from http://www.howtoforge.com/installing-the-lltd-protocol-responder-for-linux-on-debian-lenny and made a bit more direct for those that just want to make it work and not pay attention to what you're doing! Like me!

So let's dive right in.

$ mkdir lltd
$ cd lltd
$ wget http://download.microsoft.com/download/b/8/e/b8eee444-f8d5-4b8b-aa3d-2f19bf19ac72/Rally-LLTD-PortingKit.exe
$ unzip Rally-LLTD-PortingKit.exe
$ sudo apt-get install linux-headers-`uname -r` build-essential

On some debian systems you may need to specifically find the correct headers for you. For instance on one of my machines I was running Debian kernel 2.6.18-6-k7 and uname -r returned this string. However in my repositories the linux-headers package I required was named linux-headers-2.6-k7. Note the lack of the minor version number.

$ cd "Sample Code/native-linux/"
$ sudo -s
$ echo "#include <linux/if.h>" >> /usr/include/linux/wireless.h
$ make
$ cp lld2d /usr/sbin/
$ cd /etc/init.d/
$ wget http://neverfear.org/resources/lld2d

The init script assumes you use eth0 as your network interface, use INTFACE variable to change that assumption.

The code for the lld2d init script is given at the end of this article.

$ chmod 755 lld2d
$ /etc/init.d/lld2d start
$ exit

You may now delete the original lltd directory and all it's contents. The LLTD responder should now be active!
