Linux View network card traffic six ways This article introduced the Linux to see the network card traffic six methods, Linux system using Nload, Iftop, Iostat and other tools to view the network card traffic, the need for friend

Nbsp; Ifconfig command to let the LINUX core know some network interfaces such as software delivery and network card, so that Linux can use them. In addition to the usage described above, the ifconfig command is used to monitor and change the status of network interfaces. It

(I) Network Interface① Naming rulesThe Linux kernel specifies a different prefix for the interface name based on the interface type. After the prefix, a number is assigned to each interface from scratch.For example:All Ethernet interfaces start with ETH. eth0, eth1, and eth2 indicate the first, second, and third Ethernet cards respectively.② Display Nic configuration informationOnly active NICs are displaye

TC is short for Linux traffic control. The principle is to use qdisc (queue Discipline) the filter mechanism and the filter mechanism exile different rule definitions into sub-qdisc of different classes (this is true for classful qdisc, and only one root qdisc for classless qdisc ). There is a lot of information about TC on the Internet. This article will not discuss the use of various TC qdisc, class, filter or different classful/classless classes, h

BecauseLinuxWe often need to check the traffic in Linux. The following three methods can solve the problem of checking the current traffic. Iftop ToolPurpose: monitors the network status and bandwidth used by each IP address in real time.

Linux network security skills-network intrusion check The log file in the operating system is an important clue for detecting network intrusion. Of course, this assumes that your logfile is not damaged by the intruders, if you have a server that uses a leased line to connect directly to the Internet, this means that yo

Linux has always been impressed by the server level. although some people use it as a desktop or a mobile phone, it is a minority, almost no one has ever put it on the backbone network as a router, even if it is the access layer, almost no one uses Linux. The Netfilter mechanism can change this... linux has always been
