常常我们有需要一个网卡象windows一样设置多个IP。 下面我们看看在ubuntu下怎么样做. 我们先打开网络接口的文件 sudo gedit /etc/network/interfaces 照上边eth0添加eth0:0 auto eth0iface eth0 inet staticname Ethernet Lan cardaddress 192.168.1.1netmask ...

在Linux下有时候需要给一个网卡绑定多个IP，本文介绍在Redhat系列（redhat，Fedora Core，Centos）中的实现方法和一种在Gentoo等其他Linux中普遍适用的方法。　　　1、单网卡绑定多IP在Redhat系列中的实现方法　　　假设需要绑定多IP的网卡是eth0，请在/etc/sysconfig/network-scripts目录里面创建一个名为ifcfg-eth0：0...
