mellanox nic

The lab server is dual-nic, one connected to the Intranet, and one connected to the Internet. Set proxy on the server, and all machines in the LAN share the internet. However, the server system is Server 2008. I want to use Linux and do not want to change the system. So I installed a virtual machine and Linux on the virtual machine. To enable SSH connection to Linux in the VM over the Internet, the NIC of t

From CentOSRHEL7, the foreseeable naming rules have changed to default. In this rule, the interface name is automatically determined based on the firmware, topology, and location information. Now, even if you add or remove a network device, the interface name remains fixed without reenumeration, and can be replaced seamlessly with the broken hardware. Change the NIC name to eth0. The CentOS operating system is used as an example. 1. Modify the grub S

Set dual-physical Nic to virtual Nic in Linux To provide high network availability, We need to bind multiple network cards to a virtual network card to provide external services. This can prevent a network card from being damaged or connection interruption caused by network connection failure. In Linux, we will use eth0 and eth1 to virtualize bond0 as an example: ------ prerequisites for binding: the chipse

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.

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.

The 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.The production environment server is: DELLThe NIC is: FiberBond needs to modify the NIC configuration file involved/etc/network-scripts/ifcfg

After many tests, I finally found a method with a success rate of 99% (I dare not say that 100% was successful, but at least I tested it over 10 times) First, create a virtual machine (assuming that the virtual machine named "win_xp_sp3" is created, and the sto
