with, mainly in the following aspects of the embodiment: First, the use of very few tools, write applications are basically integrated development environment, then a tool, the compilation of successful basic can be used. Second, debugging the code is the most convenient, add some print statements, and then run to find the logical structure of the error. Very time saving Third, there is a mistake, online a paste, basically solve the problem. Difficult point: Write an application logical structu

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

Online there are many ways to modify the MAC address under Linux, most of the gourd painting gourd, seems to have not been verified, not to modify the purpose.After my detailed test, the problem was finally solved successfully.Myth One:#ifconfig eth0 Down#ifconfig eth0 hw ether 00:aa:bb:cc:dd:ee#ifconfig eth0 upThen restart the host.Conclusion: After modifying the MAC address in this way, the MAC address will be restored automatically after restarting the host system.Myth Two:#ifconfig eth0 Down

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

Try to modify the NIC address of your machine to the MAC address that someone else can access the Internet normally.

Now, they need to be replaced with a 10-Gigabit Nic. Because a 10-Gigabit Nic is a card and a port,

How to send packets from the network adapter: ArticleSource: http://blog.21ic.org/user1/1066/archives/2007/40803.html An IP packet can be considered as a packet. Linux NIC DriverProgramAdd a 14-byte MAC header to the IP packet to form the Mac packet. The Mac package contains the MAC address information of the sender and receiver. Since it is the MAC header information created by the driver, you can enter the address information at will, and th

For the server, network equipment Stability is also more important, especially the network card. In a production-type system, the reliability of the NIC is even more important.Multiple NICs are bound to an IP address, and when a network card is physically damaged, another NIC is automatically enabled and provides normal serviceThat is: By default, only one network card works, the other network cards do back

We all know that any site on the network, including routers, switches, servers, and general sites, must communicate with the network through the NIC. As the number of sites on the network increases, the use of network cards naturally increases. Nic faults also increase significantly. Many users do not pay enough attention to the network card. For example, the cheapest network card is tens of RMB, while the

Rhel7/centos7 Configure Network TeamingThe network teaming can federate or merge physical networking interfaces to form logical network interfaces with higher throughput or redundancy. It appears as an alternative to the NIC binding, which coexists with the traditional bonding mode in the system.1.
