对一台vmare上的Linux 进行了如下配置:
auto eth0
iface eth0 inet static
address 192.168.0.21
gateway 192.168.0.1
netmask 255.255.255.0
dns-nameservers 192.168.0.1
auto eth1
iface eth1 inet static
address 192.168.1.21
gateway 192.168.0.1
netmask 255.255.255.0
dns-nameservers 192.168.0.1
auto eth2
iface eth2 inet manual
up ip link set dev $IFACE up
down ip link set dev $IFACE down
然后输入命令ifconfig -a,得到:
