Consider running: # netstat -tulnp which will, run as root, identify all the listening ports on your system, UDP, TCP, IPv4 and IPv6, and -- special for root -- tell you the process name as well. Anything that has a local address of 127.0.0.1 is only offering services to other processes on the same box. Processes with a specific local address are listening only on that IP address -- this is mostly interesting if you have several networks connected. Most processes will be listening on every available IP address. -dsr-
