The servers in the company are going to use bonding these days, the main is to do double network card redundancy, the Internet is said the most is the "FreeBSD on the double card binding to improve the bandwidth of the practice", research a bit, the results to everyone said that Linux is very simple, here is not to say, according to the online information on the line. FreeBSD a little bit difficult, engaged in a few days, the initial use of LaGG module, according to the Manual of the "link Aggre

Starting from the very beginning, we began to deal with complicated problems, which would inevitably make people feel stunned and stretched. The same is true for reading Linux Nic drivers.

Early in the morning, a friend said that the dual Nic configuration in the Linux environment, sometimes get the IP address, sometimes cannot get the IP address to change the NIC speed, and now it is normal. But it cannot be used at the same time.
I searched for information on the Internet and wrote a solution as follows:

This article describes in detail how the target kernel driver cannot support the current Nic device.01. Co
In the "Device Manager" on the computer, many people have names such as "#2" and "#3" behind the network card. If your computer has only one network card, this indicates the driver of the NIC.ProgramYou have been installed on your computer at least twice. Why is this happening?
This is because you have changed the expansion slot of the NIC. For intentional or unintentional purposes, you may change the NIC
Many home users access the residential broadband through ADSL dial-up Internet access. When using this method to access the Internet, they often encounter a failure in dial-up Internet access! This is not the case. When we perform hardware plugging and unplugging operations on the computer at will, some Nic devices are "allergic" to this kind of plugging operation, resulting in the failure of dial-up Internet access. Now, this article will contribute
