Editor to share with you the use of linux's iptraf command to monitor network card traffic in real time. I hope you will gain a lot after reading this article. Let's discuss it together.

The full spelling of the iptraf command is "IP traffic monitor". The iptraf command can monitor the network card traffic in real time and generate information such as network protocol packet information, Ethernet information, network node status and ip checksum errors.

The iptraf command supports both command line and menu operation. When there are no parameters, the iptraf command will enter the menu operation mode and perform the corresponding operation through the on-screen menu.

Syntax format: iptraf [parameters] [Nic]

Common parameters:

-I immediately enable IP traffic monitoring on the specified network interface-g immediately starts generating summary status information of the network interface-d immediately starts monitoring detailed network traffic information on the specified network interface-s starts monitoring TCP and UDP network traffic information immediately on the specified network interface-z displays the packet count on the specified network interface-l starts monitoring the office immediately on the specified network interface Web workstation information-t specifies the time that the command monitors-B redirects the annotation output to "/ dev/null" Turn off annotation input and run the program as a background process-f clear all counters-h display help information

[root@linuxcool] # iptraf-I eth0

Monitor the detailed tcp/udp traffic of the Nic eth0:
