Ubuntu Specifies static IP

By default, Ubuntu uses DHCP to obtain IP, but it is easier for users to configure the network, but it is not good for multi-user LANs, because DHCP occasionally replaces IP, which means that the user who wants to connect must change the IP configuration.

The method for specifying static IP is as follows:

1. Edit/etc/network/interfaces, as follows

auto　eth0
iface　eth0　inet　static
address　　192.168.1.100　　　　＃静态ip
gateway　　192.168.1.1　　　　　　#网关
netmask　　255.255.255.0　　　　#子网掩码

2. Edit/etc/resolv.conf, specify DNS

NameServer 192.168.1.1

3. Restart Network Services

/etc/init.d/networking restart

OK,IP already specified!
