IPTraf - network analyser
IPTraf is a console-based network statistics utility for Linux. It gathers a variety of figures such as TCP connection packet and byte counts, interface statistics and activity indicators, TCP/UDP traffic breakdowns, and LAN station packet and byte counts.
- An IP traffic monitor that shows information on the IP traffic passing over your network. Includes TCP flag information, packet and byte counts, ICMP details, OSPF packet types.
- General and detailed interface statistics showing IP, TCP, UDP, ICMP, non-IP and other IP packet counts, IP checksum errors, interface activity, packet size counts.
- A TCP and UDP service monitor showing counts of incoming and outgoing packets for common TCP and UDP application ports
- A LAN statistics module that discovers active hosts and shows statistics showing the data activity on them
- TCP, UDP, and other protocol display filters, allowing you to view only traffic you're interested in
- Supports Ethernet, FDDI, ISDN, SLIP, PPP, and loopback interface
- Utilizes the built-in raw socket interface of the Linux kernel, allowing it to be used over a wide range of supported network cards.
- Full-screen, menu-driven operation.
- IP, TCP, UDP
- ICMP, IGMP, IGP, IGRP
- OSPF, ARP, RARP
Non-IP packets will simply be indicated as "Non-IP" and, on Ethernet LAN's, will be supplied with the appropriate Ethernet addresses.
