Binding multiple NICs in Linux CentOS recently touched on a piece of server load. The following describes how to bind multiple NICs to IP addresses in Linux. Here is an experiment using CentOS6.3, the environment is completed under VMware Workstation 9. First, there are two Nic devices in the CentOS System of the Virtual Machine Linux. Here, we use NAT for the convenience of using the CRT software SSH. Let'

If the network is expanded with only one Nic installed on the server and All workstations use the bus structure to access the Internet, the access speed will be slow. In addition, if a workstation fails during Internet access, All workstations are affected and cannot work. We can install multiple NICs on the server to solve the problem. In this way, the server not only works stably, but the workstation's Internet access speed will be greatly improved.

Wireless NICs in a Samsung notebook are usually automatically started by default. If you find that the wireless Nic is disabled or disabled when using the notebook, you can enable it as follows: Method 1: 1. Press [FN] + [F12] to enable the wireless Nic. 2. At this time, there will be a wireless activation prompt in the middle of the screen, such: Method 2: 1. Press [FN] + [F1] to open the "Easy Settings" software. 2. Click wireless networks on the l

Because it is too long, we need to reduce the network adapter speed to 10 Mbps when using it in windows. If it is automatically configured, the connection will be connected at a speed of Mbps by default, but the connection will be unstable during the disconnecti

To install Ubuntu server 10.04 with virtual box in Ubuntu, you need to connect to the Internet to install software, but you also need to access it on the local machine. If you want to assign an intranet IP address, you need to configure a bridge, I used it once before, which is too troublesome. Therefore, we consider using other solutions, such as two NICs for the virtual machine, one Nat mode and one host-only mode. Since Linux can only have one defa

Article Title: wireless network adapter active 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 order to experience the convenience of wireless networks, I purchased a laptop. However, the built-in PCI wireless network card does not have a driver in Linux, so it is useless. By chance, I found the NdisWrapper Software Project (http://ndiswrapper.so

The device List displays the old hardware list and opens the "Network Adapter ", right-click the translucent old ENI and choose "detach". Then, click "Operation> scan hardware changes" to restore the original ENI that is not #2. In addition, you can also delete the old Nic model and TCP/IP settings in the registry. The location is under the [HKEY_LOCAL_MACHINE \ SYSTEM \ controlset001 \ Control \ Network

In Linux, you can easily bind multiple NICs to achieve load balancing and dual-line hot backup. Server Load balancer distributes the load evenly to any number of network adapters to achieve dual-line hot standby with overlapping bandwidth. That is, multiple network adapters are backed up to each other. The normal operation of the network can be ensured by any network adapter. Mode = 0Round-robin: sequential (polling load balancing, the most common) mo

loads the newly installed modules. I found that the modules are not loaded. Why? The reason is that, after the system re-installs the driver module, the system usually loads it after the restart. If it cannot be loaded, run the following command: you do not need to specify the path for insmod + specific paths and modules or directly using modprobe. After restarting, let's see if the system can automatically load modules: However, to complete the correspondence between the nic and the module,
