My centos5.5 NIC driver is r8169, and the latest driver is r8168 on the official website. This makes me feel weird. doesn't r8169 represent the driver version, or r8169 is not officially developed. Just in case. The following describes how to replace the NIC driver instance in centos5.5. 1. view the Nic model and machine number of digits. 1. view the

For centos7 users, the NIC naming rules become very strange, making the nic name completely different from the eth series naming method we were familiar with before, in this way, it is inconvenient to use or view it. next I will explain how to return to the traditional naming. for the newly installed centos7 system, we can use it #: ifconfig command to view the initial configuration information of the

Now the Internet cafe's hardware environment is getting better and better, mainly because the configuration is getting higher and higher, the client memory is getting bigger and bigger, and the server is also the same, so many people are gradually entering the "virtualization" era, from Initial game virtualization to current system and game virtualization, but in this implementation process, new users may encounter some problems, for a few days, the common settings of the server and client

RedHat6.5 Nic problem summary Problem description: Prepare to use RedHat6.5 to install Oracle 12c RAC. After the system environment is ready, find that the configuration of the new RedHat Nic is not the same as before. The problem and solution are summarized as follows: 1. The eth0 file cannot be found. In the use of RedHat6.5, the new installed system, found that no eth0

This article is the author of the work of learning in understanding or sentiment, welcome everyone to ask questions, discuss together!!I. Questions raisedThe general motherboard has two NIC interface, Linux system is generally named after boot eth0,eth1, of course, if we do not eth0 and eth1 post-processing, each boot eth0 and eth1 location will not be fixed. Therefore, when the external network card, the problem of port confusion (port name and port

Method One: 1. Right-click the computer--> Management--> Device Manager, as shown in figure: 2. Click Device Manager-will not see the NIC device, but in other devices one by one has an Ethernet controller, right click on the Ethernet controller one by one click Update Driver software, as shown: 3. Choose to browse the computer to find the driver software, browse location directly find the network card driver file path. As sh

What happened in these months is still quite a lot, for a new company, OpenStack Harvest or some, of course, this is to learn by themselves, but completely into an outsourced project feeling, I am a bit uncomfortable. If you do anything, you need documentation, then my creative mind is not erased? I believe in my ability to learn, so I must have consciousness, accumulated over the accumulation of thin hair. Alas, but I feel that I still have a bit of failure, life from time to time will be confu

ubuntubonding (NIC binding)binding, also known as Port aggregation or link aggregation, means that multiple network interfaces (NICs) are combined into a single link, providing high availability, load balancing, maximum throughput, or these combinations. Note that bonding can only provide link monitoring, i.e. whether the link from the host to the switch is connected. If only the link of the switch to external (such as firewall, etc.) is down, and the

How to modify the NIC after vmwarevm clones 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 original system, and there is a conflict in the LAN. You need to change the cloned MAC address. Exp

The VM deployed in ovf cannot start the NIC properly. After the system is started, the VM cannot access the Internet. If the NIC is not started through ifconfig, the NIC service is started, but an error occurs: device eth0 does not seem to be present, delaying initialization, and then think of whether the ifcfg-eth0 configuration file to save the previous MAC add

Nic binding to a single kernel process and asynchronous I/O should be able to achieve optimal communication performance, but in reality, we often find that this mode does not achieve the expected results, this may be because the NIC is competing for CPU resources with the application. The frequent occurrence of hardware interruptions is a very CPU resource-consuming task... the single process and asynchrono
