first, identify all types of network equipment and network Connections Because network virtualization adds a lot of virtual network devices (including virtual NICs) to the physical machine, the situation becomes complex, so first we need to distinguish them. Of course, if you don't have network virtualization, you can skip this section. In a networked virtualization environment, it should be visible through Device Manager: A physical network card starting with Intel (depending on the physical

Hello everyone, when I went to Lenovo a few days ago, I saw that their engineers installed several NICs on a single machine. The speed was good. I checked it and I went back to the company and found some information on the Internet, dual (multiple) NICs use one IP address technology, which is very useful for various Intranet servers and computers, and, and, I sorted out the information I found on the Internet. Let's take a look, it may be good for everyone! I personally think that using

Upgrade the current kernel (2.6.32-220.el6.x86_64) to the target kernel (2.6.33-110.el6.x86_64) as required by the project, but the compiled target kernel (2.6.33-110.el6.x86_64) The corresponding driver does not necessarily support the corresponding device of the current system. This article details the processing steps of the target kernel driver that cannot support the current NIC device.01. Compile the target kernelPlease refer to kernel compilati

Troubleshooting: First troubleshoot the installation driver during the error. Generally speaking, when a stand-alone network configuration, because the system more than once to the network card detection, making the system start slower than before, this is a normal phenomenon.

The NIC configuration file is in the RedHatenterpriselinux system. Each network medium corresponds to a configuration file, which allows the Super User to configure the NIC. These configuration files are called Nic configuration files (NICConfigureFile). Nic configuration files must be saved in/etc/sysconfig/network-sc

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

Many of the available NIC drivers have actually been installed during the installation of Gnu/linux, but this one:Realtek PCIe GBE Family ControllerBut not the driver.And my desktop: the HP HP Pro 3380 MT is just using this NIC.

In the XP system, dual-nic Internet access is absolutely feasible, and dual-host interconnection in XP is not required. With the development of the times, computers are becoming increasingly popular in today's homes, and many families already have two or more computers. For these users, how can they connect two computers together to form a minimal LAN for sharing files, playing games online, sharing printers, and other peripherals, even Internet acces

Linux Kernel upgrade-update NIC DriverThe current kernel (2.6.32-220. el6.x86 _ 64) upgrade to the target kernel (2.6.33-110. el6.x86 _ 64), but the compiled target kernel (2.6.33-110. the corresponding driver of el6.x86 _ 64) does not necessarily support the corresponding device of the current system. This article describes in detail how the target kernel driver cannot support the current Nic device.01. Co

1. Simple NIC address modification method If you access the network through the physical address of the network card, you must modify the physical address. For example, if a new Nic is changed, the physical address of the NIC is repeated, or the laptop is temporarily logged on to the network. Change the MAC address of the NIC
