"Port scanners are like the locksmiths of the digital world, exploring the doors and windows of computer networks." - Unknown
This program ‘Port Scanner’ is used to verify open ports on a device by specifying its IP address.
The program begins by importing essential libraries required for network connections, including 'socket', 'sys', and 'datetime'.
It initializes when the user enters the target IP address, and then a port scanning loop iterates through a range of port numbers from 1 to 65534.
The 'socket' library is utilized to establish connections with the target device. If a connection is not established within a certain timeout period or if the result indicates an open port, the program records this information.
The final output may include exceptions or a list of open ports within the specified range.
Ports:
An open port scanner is a network tool designed to identify and report open ports on a target device or network. It works by systematically scanning a range of ports on the target to determine which ports are actively accepting incoming connections. This information is valuable for network administrators to assess and enhance security measures, as open ports may represent potential vulnerabilities. Open port scanners can be used both for security auditing and troubleshooting network connectivity issues. Malicious activity involving an open port scanner typically entails unauthorized and potentially harmful actions aimed at exploiting vulnerable systems or networks.
