Hi, I'm looking for help on opening UDP, TCP client, and TCP listening ports as well as closing them. And also, I'm looking for software that will scan ALL my ports on this computer and display open ports. Thanks.
superscan will scan any device on a network for open ports. If not on a network there is a shields up test on grc.com that you can use to scan ports and see which are open to the world via your internet connection. You would normally open and close ports through your firewall so go to the settings in that to do this
