Ubuntu 12.04 Network Settings, custom IP address

1, server version

Set IP address

Ubuntu 12.04 's network settings file is/etc/network/interfaces, open the file and you will see

Auto lo
iface lo inet loopback

The setting here is the local loop. Add in the back

Auto eth0
iface eth0 inet static
address 192.168.1.230 (IP)
netmask 255.255.255.0 (subnet mask)
Gateway 192.168.1.1 (Gateway)

Eth0 is the computer network card, if the computer has more than one network card, such as there will be eth1, can be set up here. Iface eth0 inet set to DHCP is dynamically acquiring IP, set to static with a custom IP. Here to customize the IP address, so select the static option.

Restart Network Services

sudo/etc/init.d/networking restart

Restart good, with ifconfig look down eth0, is not changed to their own needs of the IP address.

Setting up DNS

IP settings, if the direct ping www.baidu.com will find ping impassability, because DNS has not been set up, edit/etc/resolv.conf, plus the DNS server address.

NameServer 8.8.8.8
nameserver 8.8.4.4

These two are the IP addresses of the free DNS servers provided by Google.

Ps1:ping hint, connect:network is unreachable, mostly gateway problem

sudo route add default GW 192.168.1.1

Vi/etc/resolv.conf
