Port Scanner using Python

-

 

Code Example

What are Network Ports?

Network ports are the communication endpoints for a machine that is connected to the Internet. When a service listens on a port it can receive data from a client application, process it, and communicate a response. Port scanning is part of the first phase of a penetration test and allows you to find all network entry points available on a target system.


Common TCP Ports Listing :

  • 21 - FTP (File Transfer Protocol)
  • 22 - SSH (Secure Shell)
  • 23 - Telnet
  • 25 - SMTP (Mail)
  • 80 - HTTP (Web)
  • 110 - POP3 (Mail)
  • 143 - IMAP (Mail)
  • 443 - HTTPS (Secure Web)
  • 445 - SMB (Microsoft File Sharing)
  • 3389 - RDP (Remote Desktop Protocol)


    To Run port scanner: 

    (venv) C:\Users\kuntal\Desktop\New folder\code-example\Port Scanner>python portscanner.py 192.168.1.103
