What are Packet Analyzers for Linux?

Packet analyzers, also known as packet sniffers or network analyzers, are tools used to monitor, capture, and analyze data packets traveling through a network. These tools help network administrators troubleshoot issues, optimize performance, and detect security threats by examining the content and metadata of transmitted data. Packet analyzers operate by intercepting network traffic and displaying information such as protocols, source and destination addresses, and payload details. While beneficial for network management, their misuse can pose security risks, such as unauthorized data interception.
