决议

Install and run the iptraf utility as the root user:

Red Hat Enterprise Linux 8: yum install iptraf-ng -y and run the iptraf-ng command
Red Hat Enterprise Linux 7: yum install iptraf-ng -y and run the iptraf-ng command
Red Hat Enterprise Linux 6: yum install iptraf -y and run the iptraf command
Red Hat Enterprise Linux 5: yum install iptraf -y and run the iptraf command
Red Hat Enterprise Linux 4: up2date iptraf and run the iptraf command

Usage

When iptraf is run, a text-based interface will appear as below:

Press a key to continue. The main menu appears:

Choose the IP traffic monitor option. A new menu with a list of all network interfaces will be shown:

Select the interface you wish to monitor. Basic statistics about the interface will be shown such as Packages Captured, TCP Flow Rate, and so on.

Detailed interface statistics provides information about the network interface:

iptraf can be configured with the Configure... option:

If you wish to monitor a specific port, or set of ports, this can be done from the Statistical Breakdowns option:

Select to **Filter...* by packet size or by TCP/UDP port:

Select the interface to monitor on:

A filtered display shows statistics as follows:

The TCP/UDP port range can be changed from the Configure... section, inside Additional ports...:

根源

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.

Support many protocols such as: IP, 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.
