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,

Writing time: February 22, 2015 Sunday 1 overviewWith the promotion and acceptance of the public cloud, we find the value and advantage of the public cloud, but in many scenarios we still need to deploy many network virtual appliances, and for most of these network virtual appliances deployed in Azure, multi-NICs are a basic requirement and need to provide greater capacity to manage network traffic. The multi-NIC feature allows you to create and manag

Windows Server 2012 supports up to 32 network cards in a "dual live" mode, which increases throughput by 32 times times.Group mode:switch-independent (Switch independent):This is the default when configured, this mode does not require the switch to participate in the combination configuration, because the switch in standalone mode does not know that the NIC is a part of the host,the NIC in the teaming group

This problem is often encountered. The old network card is broken and a new network card is changed. When you set the previous ip address, the pop-up always conflicts with the existing ip address. Although it does not affect usage, it affects mood. I found a solution post on the Internet and used 2nd methods to solve the problem. So make a note to facilitate future callsThe following is a post:The old Nic of the machine conflicted. the problem that th

Editor's note: In the network system, although the network card is small, it is not enough if it is missing. These two articles talk about The Troubles caused by network cards. I would also like to remind you that if there is a problem with the network, you should not only consider the switch or something. Maybe your bad network card is secretly enjoying it.Attackers cannot access the Internet. In the usual network management work, many network faults occur, and of course many network card fault

Obtain the network interface device [Nic device] To capture network packets, you must first obtain the network interface device of your computer, which is also called the NIC device. the jpcap package provides us with this [static method]: jpcapcaptor. getdevicelist () is a list of Network Interface Devices, networkinterface class, and network interface class. It encapsulates the corresponding network port
