This chapter isn't so much about the physical alarm system per se as it is about protecting your home network from intruders. BeagleBone is connected to your home network, so it might as well do something in its spare time.
What we are going to do is install two small but very useful open source network monitoring software packages. The first package that we will be installing is MTR, which stands for MyTraceRoute. Anyone who has ever used trace route in either Linux or Windows will know that it is used to find the path to a given IP address.
Installation could not be simpler. Perform the following steps for installing MyTraceRoute:
/usr/src/directory and then type:
wget https://launchpad.net/mtr/main/0.85/+download/mtr-0.85.tar.gz ...
