On the centos server, configure a NIC configuration (linux and automatic Nic startup). The NIC configuration file is stored in the directory:/etc/sysconfig/network-scripts/specific configuration file: ifcfg-xxx; for example, eth0 is a ifcfg-eth0, lo is ifcfg-lo # Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) TYPE = Ethernet # network adapter type

Linux load balancing based on two-NIC binding technology for PlatformMaintaining high availability of servers is an important factor in an enterprise-wide IT environment. One of the most important is the high availability of server network connections. Network interface card (NIC) binding technology helps ensure high availability features and provides additional benefits to improve networking performance.

1. Network card basic configuration information The 1th step: first we want to switch to the "/etc/sysconfig/network-scripts" directory (this directory is stored with the network card configuration file). Step 2nd: Use the VIM editor to modify the NIC file "ifcfg-eno16777736", write the configuration parameters, and save the exit. Device Type: type=ethernet address assignment mode: bootproto=static network card name: name=eno16777736 boot: onboot=yes

Server Nic multi-nic binding and vlan supported versions: 1.0 principle: Use the 802.3ad protocol to bind multiple NICs. The 802.31p protocol is used to support multiple VLANs. Result: Through the netperf test, the traffic bound to the dual-nic can reach Gbps or above. With vlan support, the server can bind ip addresses of multiple VLANs.Software environment: bro

Tips on Nic configuration and dual Nic binding in CentOS Centos6 Nic Configuration Standard document /Etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE = "eth0" BOOTPROTO = static NM_CONTROLLED = "yes" ONBOOT = "yes" TYPE = "Ethernet" UUID = "e8d096fd-3e45-4303-8f7e-aa1808e03dba" HWADDR = 00: 0C: 29: D6: CE: 89 IPADDR = 192.168.10.119 PREFIX = 24 GATEWAY = 192.168.

In Linux, dual-nic binding is achieved by virtualizing two NICs into one Nic. In other words, two NICs have the same IP address, and parallel links are aggregated into one logical link. In fact, this technology already exists in Sun and Cisco, known as Trunking and Etherchannel technology. It is also used in Linux 2.4.x kernel, known as bonding. Under normal circumstances, the network adapter only receives

Day2 -- set the NIC through setup, day2 -- setup the NIC Configure the IP address. After installing centos, you must configure the IP address as follows: 1. First enable the VM, as shown below: 2. log on to the root account as follows: 3. Enter setup and press Enter. There are many ways to set the IP address. The simplest way is to configure the IP address as follows: 4. Press the up and down cursor, sel

Delete the hidden physical Nic and virtual Nic after network virtualization failure in Windows. In Windows, Nic problems may occur when hardware such as the hardware server motherboard and Nic is replaced, the operating system is restored, or network virtualization fails. For example, an undesired

During hardware power-on initialization, the BIOS checks all PCI devices and assigns a physical address to each device. The address is obtained and written to the configuration space of the device through the bios, And the CPU cannot be accessed directly, the driver can map this configuration space to common memory through ioremap for CPU access. When the operating system is initialized, each PCI device is assigned a pci_dev structure and the previously allocated physical address is written to t

What is an IP alias?In the words of Windows, you configure multiple IPs for a network card.When do I add IP aliases to what occasions?Web needs, multi-IP access testing, specific software for multiple IP needs ... and so on.HowHere are a few examples of how to use the Ifconfig command to configure an IP alias for a network card.For the configuration of the ip/mask/dns/Gateway/route, seeRouter/linux host/win The host's routing configuration summary. Note: Be aware that your configuration takes ef

System Center 2012 R2 POCNic for deploymentCombination and vswitch Creation What is a NIC combination? Simply put, the NIC combination is to bind multiple physical NICs on the same server to a virtual Nic through software. That is to say, for an external network, this server has only one visible Nic. For any applicat

Linux loopback NIC Driver Design, linux loopback NIC Driver Loop NIC Driver1. The difference between a back-to-loop network card and a common network card is that it is virtual rather than a physical network card. It is equivalent to concatenating the sending end and the receiving end of the common network card.2. in the kernel source code, the loopback

Ww7109(Stranger)04-08-23 How can I obtain the MAC address of the NIC in the kernel? You can obtain the MAC address based on the NIC name. Reply ArticleOption:

Today in the VMware virtual machine installed centos6.5, select Hardware, do not select the network card, the system started, found that there is no network card, then select the virtual machine in VMware-"Settings-" Add-"network adapter, add network card,Start the system, after entering the system, the ifconfig command found that there are only two network cardsUse Ifconfig-a to view eth0 Nic foundUse the command ifconfig eth0 up boot network card wh

TCP/IPThe Protocol has long been the standard language of the network. With the advent of Internet SCSI and remote diret memory access, TCP/IP has become a storage protocol.We know that using the TCP/IP protocol to process network traffic requires a large amount of server resources. To reduce the pressure on the server, a TCP offloadEngine: Toe) technology came into being. The TCP burden reduction engine is generally composed of two components: hardware and software. It extends the functions of

MAC (Medium/media Access Control) address is for the network card, the manufacturer in the production process, the network card in its EPROM burned in a group of numbers, this group of numbers, each net card is different, this is the MAC (physical) address of the network card. That is to say: A network card corresponds to a unique MAC address. 　　The difference between MAC address and IP address The MAC address is used to define the location of the network device. In the OSI model, the third la

Compile and install the NIC Driver in linux (NIC packet loss)-Linux Enterprise Application-Linux server application information. The following is a detailed description. Install and compile the NIC Driver In the past two days, I found that the packet loss of a server is very serious. The snmp package can be obtained when the cacti monitoring tool is used, which i

Linux OS uses 3g Nic and linux OS 3g Nic A few months ago, opensuse13.2 came out, but it was always itchy. At that time, I had been using the campus network and had not used a 3G Nic for a long time. When I got home, I set up a 3G network card, but it didn't respond when I plugged it into the computer. I was always prompted to create a network connection or somet

The new Nic device is not hosted in centos6.5, And the NIC is in centos6.5. This is the case. I am a linux cainiao, installed the centos6.5 system on the physical machine, and added a new Nic, however, on the graphic interface, the newly added Nic displays the status of the device that is not hosted, Then I checked a
