In Windows to set up a network card multiple IP, it is easier, today I write about in the Linux system, to a network card set multiple IP address, under the Linux system, the first card is called Eth0, the second network card is called eth1, Here we give the first network card set multiple IP, under Linux, configure the network card configuration file in the directory/etc/sysconfig/network-script/, the original network card configuration file named Ifcfg-eth0, We give a network card configuration of multiple IP address configuration file named Ifcfg-eth0:1 and Ifcfg-eth0:2, the following operation is as follows: Last Login:fri 6 00:35:49 from 172.28.102.41
