One: Principle: Linux operating system under the two-NIC binding has seven different modes. Now the general enterprise will use dual network card access, so that both can add network bandwidth, but also to do the corresponding redundancy, can be said to be a lot of benefits. And the general enterprise will use the Linux operating system with the network card binding mode, of course, now the network card manufacturers will also be some for Windows ope

Double NIC binding order IP address in order to provide high availability of the network, we may need to bind multiple network cards into a virtual network card to provide services, so that even if one of the physical network card failure, it will not cause connection interruption. Multiple NIC bindings. In order to provide high availability of the network, we may need to bind multiple network cards into a

2013-08-20 15:39:31 Many servers now come with dual gigabit network ports. Using Nic binding can increase network bandwidth and make corresponding redundancy. Currently, it is used in many scenarios. In the NIC binding mode of the linux operating system, the Linux bonding Driver provides a way to bind multiple network interface devices to a single network interface setting for network load balancing and net

Due to business needs, three Linux servers in the foreign data center need to add one physical Nic each. Previously, no Nic operation was performed on the physical server, which is a supplement of experience. Linux system version: ScientificLinux6.5x86 _ 64 Server model: Fujitsu suprimergyrx200s8 New Nic model: IntelI350-T2 Due to business needs, three Linux ser

> 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: The Troubleshooting steps are as follows:: 1: Check whether the system recognizes the corresponding NIC (no eth0 Nic exists ): Based on the displayed information, we can preliminarily determine that the system

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

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

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. I installed solaris 10 for x86 u3 on the PC for testing, and successfully recognized the intel Nic when installing the system. Yesterday, my colleague p

It is impossible for a dual-nic computer to have two gateways, because the default gateway can only be one. Install two NICs for the UbuntuLinux server and set different ip addresses and gateways (intranet and Internet) respectively. The Internet can be accessed through the Internet Nic, and the Intranet can be accessed through the Intranet Nic, it seems very eas

In RedHatlinux, if you set the fixed ip address of the NIC in redhat-config-network under xwindow, the setting of the fixed ip address of the NIC does not work. If you set it, the ping will fail. Check some information, change/etc/sysconfig/network-scripts/ifcfg-eth0 (the first Nic is eth0), configure the dns file as/etc/resolv. conf, I keep the dhcp configuratio

I thought Winpcap would provide this function, but after reviewing packet32.c and its driver code, I found that no interface was p

After explaining the framework of the dm9000 NIC Driver in the first blog in this series, we should analyze this "giant thing" for beginners by module. This article first explains the. Driver and.
