@mojoman: These should provide the info you want:
Code:
netstat -ant
netstat -anu

The first lists all TCP ports in use, the second the UDP ports. The column "Local Address" will likely list 5 (or 6) possible different addresses
  • 127.0.0.1 is the local host. Those won't accept connections from the outside
  • 0.0.0.0 is a general port. Those listen on any assigned address
  • 3 IPs for the regular & the 2 "virtual" addresses. Everything listed there will listen only on that address
  • Maybe the '::' address if you've got IPv6, where it equals the 0.0.0.0 address.
I was just answering him. h e told me in his email.
