What is a Port Scanner?
Port Scanners are required to perform an Exploit attack. When you attempt to hack another user using an Exploit, the Scanner will scan all vulnerable ports, one port for each of your Exploits, (If you have more than one running). Your Port Scanner must also be a running process in order to work. There is not much else to say, so no example will be given on using this Software.
At this current point in the game, Port Scanners are Non-Researchable.
Where can I get the Port Scanner?
Simply head on over to the Download center, where you will find a software named 'Basic Port Scan'. Download that, and you're ready to go.
How do I research my Port Scanner?
Port Scanners are non-researchable at this stage in the game.
It says I have no software to research!
This is because you have not bought the License.
Alternatively, you can go into your Software tab on the side-menu, and click the little blue circle icon that's located next to the Software's name. From there, you can buy the license, (If you haven't already), and research the software following the steps I have provided above.
