Starting from the very beginning, we began to deal with complicated problems, which would inevitably make people feel stunned and stretched. The same is true for reading Linux Nic drivers. The long source code is mixed with unfamiliar variables

Early in the morning, a friend said that the dual Nic configuration in the Linux environment, sometimes get the IP address, sometimes cannot get the IP address to change the NIC speed, and now it is normal. But it cannot be used at the same time. I searched for information on the Internet and wrote a solution as follows: 1. install and configure network devices When installing Linux, if you have a

Use the route command to resolve the following steps:1) determine the network segment of your intranet, if there are more than one listed, for example: 192.168.1.0/24,10.20.0.0/16, etc.2) Determine your intranet network card gateway IP, through NETSTAT-RT can see, for example: Here the first NIC En0 is the wireless network card, The gateway IP is 10.99.1.1, the second NIC EN4 is the wired network card, the

Tangxiang Daily-March 16, 2017:How to add multiple IP addresses to a NIC in Linux network configurationThere are two common ways that Linux systems configure VIPs for network cards: alias IP, and secondary IP=======================================Aliases IP (alias IP)The IP alias is created and maintained by the Ifconfig command of the Linux system, and the alias IP is the second and higher IP that is bound on the

This procedure to solve the CentOS system in some cases, the network card frequently failure caused by the Internet and restart can be normal after the internet phenomenon.This program automatically obtains the gateway address of the ETH0 network card, pings the gateway every 5 minutes, and restarts the NIC command according to the feedback results.After the detection is complete, the test results are displayed on the screen and the logs are saved in

hwaddr=, in which AA:BB:CC:DD:EE: The hardware address of the Ethernet device in the form of FF. On a machine with multiple network card devices, this field is very useful and ensures that the device interface is assigned the correct device name, regardless of the load order in which each NIC module is configured. This field cannot be used with MACADDR. Macaddr=, where the hardware address of the Ethernet device is in the form of AA:BB:CC:DD:EE:F

In this case, the user can see /sys/class/net/bond0/slave_eth0 pointing to /sys/class/net/eth0, and /sys/class/net/eth0/ Master points to /sys/class/net/bond0. Network c

Overview:There are currently seven types of NIC bindings mode (0~6) bond0, Bond1, Bond2, Bond3, Bond4, Bond5, Bond6There are three kinds of commonly used:Mode=0: Balanced load mode with automatic redundancy, but requires "Switch" support and settings.Mode=1: Automatic redundancy mode, where one line is disconnected, other lines will be automatically redundant.MODE=6: Balanced load mode with automatic redundancy without "Switch" support and settings.De

One: Principle: Linux operating system under the two-NIC binding has seven different modes. Now the general enterprise will use dual network card access, so that both can add network bandwidth, but also to do the corresponding redundancy, can be said to be a lot of benefits. And the general enterprise will use the Linux operating system with the network card binding mode, of course, now the network card manufacturers will also be some for Windows ope

Double NIC binding order IP address in order to provide high availability of the network, we may need to bind multiple network cards into a virtual network card to provide services, so that even if one of the physical network card failure, it will not cause connection interruption. Multiple NIC bindings. In order to provide high availability of the network, we may need to bind multiple network cards into a

Rhel7/centos7 Configure Network TeamingThe network teaming can federate or merge physical networking interfaces to form logical network interfaces with higher throughput or redundancy. It appears as an alternative to the NIC binding, which coexists with the traditional bonding mode in the system.1.
