IPTraf-ng – console based network statistic monitoring utility

IPTraf-ng is a console based network statistic monitoring utility. It’s a fork of iptraf.

IPTraf-ng gathers a variety of network traffic information such as TCP connection packet and byte counts, interface statistics and activity indicators, TCP/UDP traffic breakdowns but also LAN station packet and byte counts.

This program can be used to determine the type of traffic on your network, and what kind of service is the most heavily used on what machines, among others.

IPTraf-ng works on Ethernet, FDDI, PLIP, loopback, and SLIP/PPP interfaces. Also supports GRE-over-IP tunnels, 802.1ad and QinQ VLAN, and SIT tunnels.

It’s free and open source software.

Features include:

  • Supports IP, TCP, UDP, ICMP, IGMP, IGP, IGRP, OSPF, ARP, RARP, ESP, AH, GRE, and L2TP.
  • IP traffic monitor that shows information on the IP traffic passing over your network.
  • The General and detailed interface statistics shows IP, TCP, UDP, ICMP, non-IP and other IP packet counts, IP checksum errors, interface activity, packet size counts.
  • The TCP and UDP service monitor shows counts of incoming and outgoing packets for common TCP and UDP application ports.
  • LAN statistics module that discovers active hosts and shows statistics showing the data activity for them.
  • TCP, UDP, and other protocol display filters, allowing you to view only traffic you’re interested in.
  • Logging.
