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

Root user login, using Ifconfig to see whether the network card is normal.Linux By default is DHCP to obtain IP, when the network does not

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

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

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

In the platform, we have to take into account the network adapter or switch hardware corruption, or line failure caused by the server offline. We can use a dual-NIC binding to implement redundancy for network adapters or lines, or to increase network throughput.Configuration ExamplesCreate a configuration file for the virtual NIC Bond0Shell> #vi/etc/sysconfig/network-scripts/ifcfg-bond0 Devi

Took a day to study the Linux-2.6.30.4 version number kernel under the TQ2440 dm9000e network card driver porting. Summarize your own harvest. In fact. The Linux-2.6.30.4 version number kernel is about the NIC driver, but this NIC driver is not for dm9000e. But for the DM9000.Therefore, we need to change some of the parameters on this basis. and make the necessary relevant code. This
