PortScan 1.93 find all open ports on your network

The new PortScan 1.93, adds for mDNS. Τι είναι το PortScan; The ports of a computer are used for communication in computing. The article will take on enormous proportions if we try to describe the technical details, but you can understand how they work if you consider that ports allow interactions with other devices.

Common ports are: TCP 21 FTP, 23 port for Telnet, and the 80 port for the Hyperlink Transport Protocol (HTTP).

While it makes sense that certain ports need to be open on your system in order to be able to use the above and not only. But you should frequently make sure that only the ports you need are open.

Ports can reveal information about the services running on a device if they are open, allowing links from third parties.

The PortScan is a free portable Windows program that scans your network and displays all the open doors for each device it detects.


Advice: To find the IP address of a device you are using search for cmd.exe, run .exe, type ipconfig, and check the IPv4 address of the adapter listed there.

The program scans shared ports by default, something you can change from the scan type. The two other options provided give you the ability to scan all of your ports.

The scan is fast enough and the results are immediately displayed. Each device is listed with the IP address it uses, along with the hostname. A click on the device displays additional information that includes the Mac address of the device and all open ports detected during scanning.

What am I doing next?

One of the goals of PortScan is to check for open ports to determine if they need to be open. The best for your safety is to close all unnecessary ports.

An example: RTSP port 554 is used by Streaming Protocol Real Time which uses the Windows Media for transmission services streaming. If you are not using Windows Media with this feature, there is no need to have the port open.

As you understood to close ports you need to know which service or program is using it. If something is unknown or in doubt, an internet search or a will show you.

We should mention that some ports, especially those with the five digits, can be accidentally used by programs. For example, if you run uTorrent, you will notice that many ports are continuously open.
