Enable Nic automaticallyAfter centos 6.x is installed, You need to manually activate the NIC every time you start the system. The following methods can be used to automatically activate the NIC after the system starts.CAT/etc/sysconfig/network-scripts/ifcfg-eth0 Device = "eth0"Hwaddr = "00: 0C: 29: FC: 1c: 72"Nm_controlled = "yes"Onboot = "no" Change onboot to Ye

Recently, the new db server found that the NIC was unstable during the stress test. After the stress test was conducted for just a decade, the SERVER's response became very slow, packets are often lost during PING and SSH connections are also interrupted. At first, I thought the db server was unresponsive due to high concurrency. I can check the CPU, memory, and hard disk I/O, and found that none of them reached a high value, it is even much lower tha

CentOS 6.X NIC (eth0) automatic activation method 1. automatically activate the NICAfter CENTOS 6.x is installed, You need to manually activate the NIC every time you start the system. The following methods can be used to automatically activate the NIC after the system starts. vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE="eth0"HWADDR="00:0C:29:FC:1C:72"N

Eth0: Error: no suitable device found: no device can be connected to 'System et0' This error is reported when you restart the NIC when you use Putty to remotely connect to the linux6.0 system: The following error is reported: 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M00/38/E5/wKiom1O0y-az01c0AACaOA0jSD4557.jpg "Title =" http://www.bjdcxr.com "alt =" wKiom1O0y-az01c0AACaOA0jSD4557.jpg "/> The Troubleshooting steps are as follows:: 1:

My company's product is a dual-network port. The original program is a self-written TCP/IP protocol stack, because it simply implements the simplest situation of ARP, TCP, and UDP, so sometimes problems may occur on the Internet. Later, LWIP and lightweight TCP/IP protocol stack were transplanted to a single network port product, and the problem was solved to some extent. Therefore, dual network card products also need the LWIP protocol stack. This job falls into my head. I will not repeat the p

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 Azure Platform Family of articles CatalogWindows Azure VMS, by default, are a network card with 2 IP addresses. In many cases, we need azure to support more than one network card, here is a brief introduction of the author.Suppose we create a virtual network, 3 subnet subnets, divided into named Frondend, Midtier and backend, with different CIDR addresses. Such as:　　Then we can create an azure VM with three network cards, each with a different subnet. Such as:　　In particular, there are l

How to modify the NIC after vmwarevm cloning CentOS 6.5 How to modify the NIC after vmwarevm cloning CentOS 6.5 After the CentOS6.5 system is installed on the vmwarevm, the pure system is cloned several times for later testing. The clone process is very simple. The problem after cloning is that the MAC address of the cloned Nic is the same as the MAC address of

The registration and initialization process of the pci NIC Driver is implemented. the TCP/IP protocol stack and the pci protocol stack are implemented after soft interruptions occur.0x01 reason The purpose of this study is to follow the outline below: The three handshakes, data transmission, and four handshakes are debugged by the server client program. The setup environment is as follows: debug the Linux kernel environment in the Early Stage From the

This article mainly introduces the implementationOracle 10gDatabaseRACFunctionalBind two NICsWith the implementation method of Unbinding, let's take a look at this process. I. Overview of software and hardware Environments Two redhet Enterprise-R4-U4 systems rac1 and rac2 are installed on the Virtual Machine VMware GSX Server, and the oracle10g RAC environment is built on the virtual shared storage. 1. rac1 two NICs: eth0: 192.168.2.111, eth1: 10.10.10.11. 2. rac2 two NICs: eth0: 192.168.2.112 a

Run the command kudzu -- probe -- classnetwork to configure the driver for the redhat Nic. The model of the NIC and the number of NICs on the machine are displayed. run the command to check whether the kernel package is fully installed. The details are as follows: if the installation is complete, the following packages are displayed: kernel-xen-devel -... Run the command kudzu -- probe -- class = network to

Article Title: how to view the current Nic version in Linux. 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. In linux, the NIC Driver is added as a module. Therefore, you can use lsmod to view the currently loaded module, that is, the

arrangement, printer internal mechanisms, etc. But for the NIC, let's see whether it is a character device or a block device. If it is a block device, can it read and write data randomly? Looking at the features of the network card, the other end of the network card is another world, it is more like a pipe, it is more like a character device, because random read/write to a pipe is meaningless, is it a character device? You need to know that the netwo

Linux Nic compilation-general Linux technology-Linux technology and application information. For details, refer to the following section. When installing the linux system, you may encounter a problem, that is, after installing the system, the NIC cannot recognize it. This is a headache. There are two ways to solve this problem: first, buy an independent NIC and

Centos6.4 modify the NIC name In my work today, the NIC interfaces of one server in centos6.4 are em1 and em2, And the NIC interfaces of other machines are eth0 and eth1. Because the script involves reading the NIC information, therefore, in order to better manage these game servers in a unified manner, I decided to ch

In the installation and deployment process of RAC, it is not just a simple installation. The possible single point of failure (spof) should be considered during the installation process. The most important part is the private network. A private network is a channel for communication between RAC nodes, including network heartbeat information between nodes and data blocks transmitted through cache fusion. Many private networks only connect to a vswitch with a single

NIC Binding technology has been out for a long time, in different platforms under the name of different, in Linux called BONDING,IBM called etherchanel,broadcom called Team, but the name of how to change, the effect is to two or more network card as a network card use, Increase the bandwidth at the same time can also improve redundancy, seven modes, generally used more is to improve redundancy, respectively, and different switches connected to improve
