Τι είναι το PortScan; The ports of a computer are used for computer communication. The article will get enormous dimensions if we try to describe the technical details, but you can understand their operation if you think the ports allow interactions with other devices.
Common ports are: TCP 21 FTP, port 23 for Telnet and port 80 for protocol hypertext transfer (HTTP).
Ενώ είναι λογικό ότι ορισμένες θύρες πρέπει να είναι ανοικτές στο σύστημά σας, για να είστε σε θέση να χρησιμοποιήσετε τις παραπάνω υπηρεσίες και όχι μόνο. 'Όμως θα πρέπει να βεβαιώνεστε συχνά ότι είναι ανοικτές μόνο οι θύρες που χρειάζεστε.
Ports or Ports can reveal information about services running on a device, if they are open, they allow third party connections.
The PortScan is a free portable Windows program that scans your network and displays all the open doors for each device it detects.
Tip: To find the IP address of a device you are using search for cmd.exe, run the .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.
Scanning is quite fast and results are displayed immediately. Each device is listed with the IP address it uses, along with the name of the host computer. A click on the device displays additional information including the device's Mac address and all open ports found during the scan.
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: The 554 RTSP port 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 ones service or which program uses it. If something is not known or in doubt, an internet search or a test will tell you.
We should mention that some ports, especially those with five digits, may be used randomly by defaultletterthe. If you are running uTorrent for example, you will notice that many ports are constantly opening and closing.
