The following is an introduction to the detailed steps of using the system's bonding to bind the network card under CentOS6.2. Note: Please turn off the NetworkManager service before configuring[root@h63 ~]# service NetworkManager status service NetworkManager startNic can be bound at one time to bind multiple network adapters, you can use IFCONFIG-A to view your network card information, such as:[Root@h63 ~]# Ifconfig-a em1 Link encap:ethernet hwaddr 78:2b:cb:30:08:03 up broadcast RUNNING

After reading the I2C official agreement document, take s3c2440 and EEPROM to verify it. Originally want to use s3c2440 SDA and SCL pin Gpio to simulate, but in the absence of an oscilloscope for a week, how can not come out, finally or give up. Even reference to Linux under the i2c-algo-bit.c and I2C-GPIO.C, Still not tuned out. If there is an oscilloscope, it may soon be possible to find the cause, and now have no idea where the problem is. In fact, the purpose of using GPIO to simulate I2C is

the data to be monitored, use Topbeat as the resource usage measurement standard, use Filebeat as the real-time Log File Analysis, and use Packetbeat to analyze online network data. There are many optional tools, such as what you know, what you like, or what you want to learn. The most important thing you need to remember is to make sure that you know your benchmark data before you start the modification operation. Performance Tuning Tool Tuna Tuna can be used to control processes and their sch

binding also runs in this mode, and modifies the MAC address in the driver, changing the MAC address of the two NICs to the same, can receive data frames of a specific Mac. Then, the data frame is sent to the bond driver for processing. Then we check the RC. in the local file, due to the carelessness of the system engineer, the NIC binding configuration is incorrect, so a slight configuration error will cause an IP address to correspond to two different MAC addresses, it will obviously cause ne

Otherwise, packet loss may occur.

The purpose of configuring a virtual IP address is to achieve high availability. After that, let's take a look at how to set a virtual IP address in ubuntu12.04.

Because "VirtualBox Host-Only Ethernet Adapter #2" does not enable DHCP, We need to specify a static IP for eth2.
