# Set static IP addresses:


# Preparation:

#1. view the network card, IP address, and subnet mask netmask in use. My name is eth0.


Eth0 Link encap: Ethernet HWaddr ec: 9a: 74: 36: c8: 8c

Inet addr: Bcast: Mask:

# IP:, netmask:

#2. View gateway


Destination Gateway Genmask Flags Metric Ref Use Iface UG 0 0 0 eth0

# Gateway:

# Dns: # generally, it works with gateways. Of course, you can also set other dns

#3. Set static IP now

Sudo vim/etc/network/interfaces


# Interfaces (5) file used by ifup (8) and ifdown (8)

Auto lo

Iface lo inet loopback

# Set Static IP

Auto eth0 # My network card

Iface eth0 inet static # static, relative to dynamic (dhcp, that is, iface eth0 inet dhcp)

Address # You can set available ip addresses in the same network segment, for example,

Gateway # gateway

Netmask # Subnet Mask

Dns-nameservers # You can set multiple dns addresses or do not set them here. edit/etc/resolv. conf

#4. Restart the NIC

Sudo service networking restart

# Or sudo/etc/init. d/networking restart

# If the problem persists, restart reboot.

# Note:

# When dns-nameservers is not set, manually add it in/etc/resolv. conf

Sudo vim/etc/resolv. cof


# In addition:

In earlier versions, you need to set resolv under/etc. conf file, and add nameserver to connect to the Internet. Otherwise, you can only access it through ip addresses and cannot parse the URL. (nslookup can view the ip address of the website. Of course, you must first have dns ).

This method is no longer recommended after Ubuntu12.04, because no matter what value you want to set in the configuration file, it will be restored to the initial state after restart. (Of course, it does not include the automatic setting of the boot script)

We recommend that you directly add the dns-nameservers <gateway ip> line to the interfaces configuration file.
