iptraf，一个控制台流量监视工具。iptraf是一款linux环境下，监控网络流量的一款绝佳的免费小软件。它拦截网络上的报文，给出报文各个部分的信息。IPTraf能够返回的信息包括：
IP、TCP、UDP、ICMP报文总数和非IP字节数。
TCP连接的源/目的地址和源/目的端口。
TCP报文数和字节数。
TCP标志状态。
UDP源/目的信息。
ICMP类型信息。
OSPF源/目的信息。
TCP和UDP服务统值。
网络接口报文计数。
网络接口IP校验和错误数目。
网络接口活动指示器。
LAN统计
IPTraf能够用于监视IP网络的负载。IPTraf使用Linux内核的内置原始(raw)包捕获接口，可以广泛地用于以太网卡，支持FDDI适配器、ISDN适配器以及任何异步SLIP/PPP接口。
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 youre 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 LANs, 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.
IPTraf packages are also included in these Linux distributions (as far as I know):
Debian
S.u.S.E
TurboLinux
Red Hat Powertools
Conectiva
Trinux
