linux ifconfig

Today, almost all mainstream operating systems and embedded operating systems provide support for the IPv6 protocol stack. in Windows XP, you can use the IPv6 install command to start the IPv6 protocol stack, in the default Linux environment, you can use modprobe IPv6 to load the IPv6 protocol stack as a module. This article only introduces the IPv6 protocol stack configuration commands under Linux. More de

5.1 Common network commands With network-related tools available in the Red Hat Linux 7.1 system, it is essential that these tools be well mastered: Category one: Setting tools 1.netconf: Netconf is part of the linuxconf provided by Red Hat Linux and is primarily used to set network-related parameters. It can be run under Consle (Text menu), or it can be run in X-window (graphical interface). In the front

Linux generally uses the ifconfig command to modify the IP, gateway, or subnet mask of a Linux host. 1. Command format:ifconfig [Network Devices] [parameters]2. Command function:The Ifconfig command is used to view and configure network devices. This command can be used to configure the network appropriately when the n

Configure multiple IP addresses in linux and ip addresses in linux The Red Hat Linux is used as an example. Assume that the original system has configured an IP Address: 192.168.0000140, the configuration file path/etc/sysconfig/network-script/ifcfg-eth0. Now you need to configure an IP address with the network segment 192.168.1. STEP (root user permission requir

Because the Linux system originated and developed on the Internet, it is born with powerful network functions and rich network application software, in particular, the implementation of TCP/IP network protocols is particularly mature. Linux has many network commands, some of which are like Pi Ng, FTP, telnet, route, netstat, and so on can be seen on other operating systems, but there are also some commands

The command to view the IP address of the other domain name is: Ping the domain/IP address to see how many gateways have been routed: tracert

box for related properties, as shown in 2.29. Figure 2.29 Nic attributes The IP address "192.168.19.1" in the figure indicates the setting of the current Nic. The IP address in Linux must be in the same network segment as the IP address. (3) First, log on to Linux locally and set the IP address through the command in example 2-1. "Ifconfig eth0 192.168.19.102"

, and the subnet mask. With the development of the Linux GUI, Linux provides a convenient and simple graphical configuration method similar to windows by running this command in Xwindows. In fact, after modifying the conf. after the modules configuration file, you also need to use the command netconf or ifconfig to configure the TCP/IP network parameters, because

network Interface (interface) is the network hardware device in the operating system representation method, such as NIC in the Linux operating system with EthX, is a positive integer starting from 0, such as eth0, eth1 ... ethX. And the common cat and ADSL interface is pppx, such as ppp0 and so on;all available network cards, names, configuration files in the machine: DMESG | grep ETH: You can see the network card startup information and the name
