Article Title: how to adjust the Nic working mode in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Currently, NICs are generally in 10/100 M adaptive working mode. when configuring Nic parameters, we seldom consider the working mode, however, on key devices with

After centos6 changes the NIC, the NIC name is auto-incrementing. For example, if it was originally eth0 and changed to eth1 after the change, the original eth0 cannot be used. you need to modify the File: When the NIC changes. when the network card is added. or when you change the network card. this file will change. modify the mac or eth * name. to adjust. 1. V

Text/Xu hongnian Recently, the company has added a new batch of computers with the following simple configurations: p42.0ghz CPU, 256 MB ddr333 memory, 80 GB hard disk, integrated graphics card and nic. This configuration can not help but increase a lot of motivation when I work. When I was excited to turn the computer on, I found that there was no problem in processing text and Image Systems, but it was unable to connect to the network. I began to

Detailed description of centos Nic configuration under the VPS server automatically activates the NIC and installs CENTOS 6. after X, you need to manually activate the NIC every time you start the system. The following methods can be used to automatically activate the NIC after the system starts. Cat/etc/sysconfig/netw

Before centos6.0, bind multiple ip addresses to the same Nic, you need to create a file similar to ifcfg-eth0: 0 to define the new ip address, and from centos6.0, it is easy to bind multiple IP addresses. Instead of creating a configuration file, you only need to modify the configuration file of the NIC.Method 1, such as the ifcfg-em1, in which you can add such a few lines:IPADDR2 = 192.168.2.101NETMASK2 = 255.255.255.0GATEWAY2 = 192.168.2.1GATEWAY2 i

the ISP and cannot be changed, try the following methods: Route change 0.0.0.0 mask 0.0.0.0 gateway-p Article 2 Q: The operating system I use on my office computer is Windows XP. I have installed two NICs. One is connected to the internal LAN of my office, and the other is connected to the Internet of ADSL cat. Colleagues from other departments use public IP addresses to access the Internet. Therefore, they can access both networks at the same time. If I want to access the Intranet, I have to d

The actual project implementation, a host has two network cards, to achieve double-connected. At this time need to the host's two network card to do bond configuration, virtual for a network card, the main way to work to ensure that the system is highly available. First, the configuration requirements of Bond the bundled two NIC chip models must be the same and have separate BIOS Chip. Second, the bond configuration process Take the eth0 and eth1 two

Multiple NICs tied together as a network adapter for load balancing and bandwidth enhancementlinux dual NIC binding an IP address, the real work is to use two network card virtual as a piece, using the same IP address, is we can get better faster service. 　　 In fact, this technology has long existed in sun and Cisco, known as Trunking and EtherChannel technology, which is also used in the Linux 2.4.x kernel, known as bonding. The principle of 1 and bo

1 What is BondThe network card bond is a kind of common technology in the production scene, which is bound by multi-net cards as a logical NIC, which realizes the redundancy, bandwidth expansion and load balance of the local network card. Kernels 2.4.12 and later versions are available for bonding modules, and previous versions can be implemented with patches. You can determine whether the kernel supports bonding with the following command:[[email pro

About the NIC chip problem on the motherboard To the Internet users know that the Internet is used to dial, so the network card is not familiar to people who used to surf the internet, and now do not need to dial, so the Internet card became an essential hardware, and the motherboard on the card chip has become an important part, together to understand: Motherboard card chip refers to the integration of the network functions of the motherboard integ

Tags: Bond team NmctlBind multiple network cards with BINDBecause of the availability of the server on the requirements are relatively high, for each function will have a redundant design, such as disk, power, network card, and even the server itself, and so on, today try to do a network card binding implementation of network card redundancy.The implementation of the NIC bindings looks somewhat like a hard disk implementing a logical volume, and is ac

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

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

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
