MTU indicates the maximum transmission unit. MTU values are not necessarily the same for different local networks. for Ethernet, MTU sets the Linux command line to modify the IP address, Gateway, and DNS methods. Method 1: Ifconfig eth0 192.168.1.18 netmask 255.255.255.0 Note: This method can make changes take effect immediately, and will be restored to the original IP address after restart. Method 2:

There are 5 search commands for Linux, respectively, as follows: which: Searches for the location of a system command in the path specified by the path variable, and returns the first search result; type: Used to distinguish whether a command is brought by a shell or provided by a separate binary file outside the shell. If a command is an external command, then the-P argument displays the path to the command, which is equivalent to the which command

Http://os.51cto.com/art/201409/450886.htmMany system administrators today use command-line tools such as Ifconfig, Route, ARP, and Netstat (collectively referred to as Net-tools) to manage and troubleshoot various network configurations. This type of tool originally originated in the BSD TCP/IP toolkit and was designed to configure the network capabilities of older Linux kernels. Since 2001, it has stalled

Because the Linux system originated and developed on the Internet, it is born with powerful network functions and rich network application software, especially TCP/I 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.

assigning an address to the bridge port, you can configure the Gateway as the bridge port address for other subnets. Of course, because the device is in the Gateway mode, routing and nat are also required. If the device is in the bridge mode, the routing and nat can be saved.
