If you have installed the heartbeat-stonith package, you will have the "ssh"
module available. Setup the nodes so they have non-password protected ssh
login on eachother (ie, set the ssh keys / authorized_keys), select STONITH
in the menu and put "ssh" into the device field.

However, ssh is just for testing and will not work if you have lost network
connectivity to the other node; ie, you can't use it to test power failures on
the node, but have to simulate them by something like "kill -9 -1" or similar.

Getting a STONITH device (any of those supported by heartbeat-stonith will do,
though I would recommend the WTI RPS-10 or NPS-230) is really the only choice
for production systems.
