Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Maintaining the high availability of servers 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 oth

address, NETMASK is the subnet mask, ONBOOT indicates automatic startup when the system starts. If you need to bind another IP address, You only need to add the file name and the eth0: x in the DEVICE in the file. LINUX supports up to 255 IP aliases 2. it is widely used to bind multiple IP addresses to a single NIC. Ifconfig eth0: 1 192.168.0.3 broadcast 192.168.0.255 netmask 255.255.255.0 You can add the preceding command to the self-running startup file. under Gentoo, it is/et

To install strongtuserver10.04 with virtualbox in Ubuntu, you need to connect to the Internet to install software, but you also need to access it on the local machine. If you want to assign an intranet ip address, you need to configure a bridge, once, it is too difficult to solve the problem by using other methods, such as two NICs for the virtual machine, one NAT mode and one Host-only mode. Since Linux can only have one default gateway, the NAT mode
