What is Netstat and its purpose?
Netstat, short for network statistics, is a command-line tool used to display information about active network connections on a computer. It provides details such as the protocol being used (TCP or UDP), local and remote IP addresses, port numbers, and the current state of each connection. Netstat can also show listening ports and routing tables.
The purpose of Netstat is to help users monitor network activity and troubleshoot connectivity issues. By using this tool, administrators can identify which applications or processes are establishing connections to external servers or devices. This information can be useful in detecting unauthorized access attempts or identifying potential security vulnerabilities.
Additionally, Netstat allows users to view established connections in real-time, providing insights into network performance and resource usage. It helps diagnose problems related to excessive bandwidth consumption or high latency by pinpointing specific endpoints that may be causing bottlenecks.
Overall, Netstat is an essential utility for network administrators and security professionals as it provides valuable insights into network activity and aids in maintaining a secure and efficient system.
