You may have noticed that
# sudo apt-get install aircrack-ngDidn't really work like it did in good ol' Ubuntu. I just did this instead:
sudo apt-get install build-essential libssl-dev libnl*
wget http://download.aircrack-ng.org/aircrack-ng-1.1.tar.gz tar -zxvf aircrack-ng-1.1.tar.gz cd aircrack-ng-1.1 make sudo make installAfter doing sudo make install, update like the instructions tell you to. Beautiful! But oh wait, I'm trying to follow the tutorial and it can't find airmon-ng as a command... did I just install that? Yup! You've got to add /usr/local/sbin to the $PATH environment variable. Easier then it sounds.
sudo nano ~/.profile
This will open a file, and after
if [ -d "/usr/sbin" ] ; then
you have to add a section with the same structure except using the file path that actually contains airmon-ng (which usually turns out to be /usr/local/sbin, but if not learn to use the "find" command, because it's useful.)
if [ -d "/usr/local/sbin" ] ; then
ctrl+x will give you the option at the bottom to save, do so (assuming you put the code in correctly)
airmon-ng should run properly after a system reboot. Good luck.
Getting the programs to actually work takes some more tinkering. If you have any questions feel free to ask in the comments.
ps. cracking someone else's wireless password is illegal. I don't recommend it.
PPS. if something isn't working let me now, I'll try to assist
