Port “139” is windows networking. That means I’m acting as a Windows’s server for whover is on the network. Whenever connecting to the Internet, make sure this is disabled. However, for internal networking, I might need it enabled for services like file sharing with other users.

“LISTENTING” means my box is acting as a server for other users. Not good.

nslookup

Use “nslookup” alone to retrieve/test the nslookup table. Enter various “server” and “www…” commands at the “>” prompt.
