I have 4 servers I'm using for running tests, with one of them acting as a controller. Adding the first system with "phoronix-test-suite phoromatic.connect x.x.x.x" worked and I can see the system from the web interface on the server. When I go to add the second system, it never shows up in the Systems tab on the server, and in the console on the system itself, it says "Idling, waiting for task assignment" (When I added the first system it said something along the lines of "System added, awaiting administrator authorization). The systems are all running Lubuntu 15.10, and aside from hostname, IP addresses, and MAC addresses of the network interfaces, are identical.
