Article Title: kernel learning-Linux NIC Driver Analysis. 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. Learning should first simplify the problem and complicate the problem. Starting from the very beginning, we began to deal with complicated problems, which would inevitably make people feel stunned and stretched

Before Windows Server 2012 we were on the server if we were to implement a dual-NIC binding, we would need the appropriate software for the server manufacturer, but now the advent of the powerful Windows Server 2012 saves us all the hassle, Because the operating system itself has a dual-NIC binding function, how to achieve this function, the following we use the experiment to explain to you:The following tw

The Linux Nic is changed from eth0 to eth1. how can I fix the problem of installing linux using wmware? after the installation is successful, the NIC is eth0 without eth1. However, after a period of time, you do not know why eth0 cannot be used, but the system automatically generates the eth1 Nic. you can use the ifconfig command to view it... the Linux

An Ethernet NIC consists of two layers of the OSI (open-party system interconnection) model. Physical Layer and data link layer. The physical layer defines the electrical and optical signals, line statuses, clock baselines, data encoding, and circuits required for data transmission and receiving, and provides standard interfaces to data link layer devices. The data link layer provides addressing mechanisms, data frame construction, data error check, t

This is the 6th chapter in the OpenStack implementation experience sharing series. In the implementation of the project, often there is the need to add delete NIC. For example, a running database instance, initially only a network card, database services and backup shared this NIC, and later to improve performance and compliance requirements need to add a network card dedicated to backup. For a long time,

1 What is NIC bindingBind multiple network cards to the same IP address to provide services to the outside, can achieve high availability or load balancing. It is not possible to set the same IP address directly for two NICs. Through bonding, a virtual one network card to provide external connection, the physical network card is modified to the same MAC address2 NIC Binding classificationThere are seven mod

? The two-Nic binding implementation is the use of two network card virtual become a network card, the aggregation of the device appears to be a separate Ethernet interface device, the popular point is that two network cards have the same IP address and parallel link aggregation into a logical link work. Depending on the features that the switch can support, the most common is a dual-NIC binding that is set

Linux virtual machines on Hyper-V is the NIC driver, and when we created a new Linux virtual machine, we found that the NIC was not available when we turned the Linux system on. Because Linux systems, whether Rhel or Ubuntu or poop, do not support Hyper-V NIC drivers. This requires us to remove the network Adapter NIC

A test machine is installed in the IDC. The system is Ubuntu9.04X64 and the master machine is IBMX336. The user needs a dual-line connection. Therefore, one Nic is used to configure the telecom address, and the other Nic is configured with the UNICOM address. After the system is installed, only one Unicom address and one Telecom address can be pinged, if the China Unicom address does not match the gateway,

Master/slave mode configuration for dual-nic in CentOS1. Overview By setting the active/standby mode for a dual Nic, when one Nic goes down, the other Nic can automatically replace the interrupted Nic to ensure normal network access.2. Implement 2. 1. View

Set ifcfg-eth0 after Nic replacement under centos Today, one of the company's service hardware is broken, and the hard disk is pulled out, switched to another machine of the same model, and the mac address is changed to a new machine, later, it was discovered that the original Nic information was recorded by centos. When the service network restart was performed, it was still the original

Nbsp; 1. the Nic machine is too new to be recognized by the existing Linux version. for example, if the Nic cannot be found, what should I do? Don't worry. First, you need to know the model of the NIC. take the new computer purchased in this lab as an example. The NIC is integrated and the model is RealtekRTL8168/8111P
