But it is always not good to solve the problem. after various searches and inquiries, I found the following very good solution. after testing, this method can perfectly solve this problem. 0.

Commands for Nic operations: 1. lsmod check whether the Nic module is loaded and whether the NIC driver is good. 2. dmesg: Check whether the NIC is detected. 3. ifupifdown enable/Stop the Nic 4. ifconfig check whether the NIC work

Multi-queue Nic is a technology that was initially used to solve the problem of network IOQoS (qualityofservice). later, with the increasing bandwidth of network I/O, the single-core CPU cannot fully meet the needs of the NIC, with the support of multi-queue NIC driver, each queue is bound to different cores through interruption to meet

Linux Multi-NIC Binding overviewThis article os:6.4 test here is four NIC bound 1 block bondWe introduce the Linux dual-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 with the same IP address and p

In the broadband Internet everywhere today, ordinary netizens and network card contact opportunities are increasing; but because the network card is naturally inconspicuous, and always hiding in the chassis inside, so people's attention to the network card is not very high. In fact, the advent of broadband Internet access in the process of slow open pages, on the Internet when the fault continues, most of the time is due to the instability of the NIC,

In Linux, dual-Nic binding technology achieves load balancing and failure protection (in Centos5 and Centos6). maintaining high server availability is an important factor in the enterprise IT environment. The most important thing is the high availability of server network connections. NIC binding helps ensure high availability and provide other advantages to improve network performance. We will introduce th

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 1 Introduction Today, almost all industries have built their own servers. Due to the special position of servers, their reliability, availability and I/O speed become very important, maintainin

Although Microsoft is popular today, many people do not want to abandon Linux. If you want to install Linux, you will find that Linux comes with many Linux Nic drivers, but there are also some uncommon Nic drivers. In this case, you need to install the Linux NIC Driver on your own. NIC Driver Installation and problems

In Linux Ubuntu, how does one modify the NIC name ?, LinuxubuntuIn Linux Ubuntu, how does one modify the NIC name? I. solution 1: 1. First, modify the physical configuration file of the NIC. If this file is not available, create a new one or copy a copy from the existing environment and modify the configuration as required. Vi/etc/udev/rules. d/70-persistent-net.

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

In-depth analysis of seven modes of dual-Nic binding in Linux, enterprises now use dual-Nic access, which can not only add network bandwidth, but also make the corresponding redundancy, it can be said that there are a lot of benefits. In general, enterprises use the Nic binding mode that comes with the linux operating system. of course, the

Vswitches are still commonly used, so I studied the switch failure caused by improper Nic mode. Here I will share it with you and hope it will be useful to you. I got to work early in the morning, my ass was not stable yet, and the Office was full of ringtones. I used to have a few computers in my office to normally access the internet yesterday, that is, the Internet access speed is very slow. Many colleagues are eager to query information online, so

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
