IPTraf

IPTraf is a Linux-based, console network monitoring tool that provides real-time visibility into IP traffic flowing through your network interfaces. It is a lightweight and efficient utility designed to help you monitor, diagnose, and optimize network performance in professional system administration environments.

Real-Time IP Traffic Monitoring

You can monitor active TCP, UDP, ICMP, and other IP packet flows in real time. IPTraf displays detailed information such as source and destination addresses, ports, packet counts, and TCP flags. This feature allows you to quickly detect heavy traffic flows and identify unusual network activity.

Detailed Interface Statistics

IPTraf provides both general and detailed statistics for each network interface, including total data volume, average incoming and outgoing rates, packet size distribution, and protocol-specific counts. This information helps you understand network usage patterns and optimize your network configuration.

LAN Host Monitoring

With the LAN station monitor, you can list all active hosts on your local network, view their MAC addresses, and analyze the volume of traffic each host generates. This capability allows you to manage your LAN effectively, identify the most active devices, and respond quickly to network issues or potential abuse.

IPTraf supports various interface types and offers filtering and logging options, making it a versatile tool for Linux system and network administrators aiming for detailed and interactive network traffic analysis.
