Set static IP address in Ubuntu to solve the problem that you need to reset after restart.

In ubuntu 8.10, gnome is used by default, and DHCP is used by default to automatically obtain IP addresses. Set the static IP address and restart it.

1. Set IP
Sudo gedit/etc/Network/interfaces

Auto Lo
Iface lo Inet loopback # Lo is the local loopback address: 127.1

Auto eth0

Iface eth0 Inet static

Address 192.168.1.152

Gateway 192.168.1.1

Netmask 255.255.255.0

Network 192.168.1.0

Broadcast 192.168.1.255 # Set the IP address of eth0

In this way, the IP address does not take effect immediately.
Sudo/etc/init. d/networking restart

2. At this time, you can ping the computer in the LAN. But cannot access the Internet because DNS is not set. The DNS information is saved in/etc/resolv. conf. Once changed, it takes effect immediately.

Sudo gedit/etc/resolv. conf

Nameserver 208.67.222.222

Nameserver 208.67.220.220

Now you can access the Internet.
