After updating stuff

The Linux machines running Negatus need these packages:

sudo apt-get install git g++ libnspr4-dev

You can then clone it, build it, and run it:

mkdir src
cd src
git clone https://github.com/mozilla/Negatus
cd Negatus
make -f Makefile.linux
./agent

When you run the agent, it looks like this:

%  ./agent
Command handler listening on 0.0.0.0:20701
Heartbeat handler listening on 0.0.0.0:20700
Query url: IPADDR=0.0.0.0%3A20701&NAME=SUTAgent
No SUTAgent.ini data.
No reboot callback data.

That's great. Ctrl-C to quit, shutdown the VM, copy or clone it, and then launch both agents. Next task: Networking
