I scanned my server with nmap and detected, that jboss was listening - on top of the ports I expected - on the ports 41234, 46503 und 54557.
After restartig jboss, the 3 ports changed to: 35422, 41901, 43141
After a 3dr restart to: 33529, 49843, 60240
Does anyone know, what these ports are for, and if and how I can disable them.
