About IPTraf

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.

Features

• 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.
• Logging
• Supports Ethernet, FDDI, ISDN, SLIP, PPP, and loopback interface types.
• 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.

Protocols Recognized

• 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.

Supported Interfaces

• Local loopback
• All Linux-supported Ethernet interfaces
• All Linux-supported FDDI interfaces
• SLIP
• Asynchronous PPP
• Synchronous PPP over ISDN
• ISDN with Raw IP encapsulation
• ISDN with Cisco HDLC encapsulation
• Parallel Line IP

The information generated by IPTraf can be valuable in making network organization decisions, troubleshooting LANs and tracking activity of various IP hosts.
