Ubuntu : Static IP Configuration in Ubuntu 14.04 and Debian 7/8

Spread the love

Static IP Configuration in Ubuntu 14.04 :

Open Terminal and become sudo.
sudo su

Then Open network interfaces file using any editor, I am using vim editor here.

vim /etc/network/interfaces

Then edit the eth0 section (In my case, I am changing eth0, your machine may have multiple NIC cards so select appropriate interface).

Here is my configuration after making necessary Changes..

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.36.31
netmask 255.255.255.0
gateway 192.168.36.4
dns-nameservers 8.8.8.8

Then reboot the system.

Now, You can verify your Static IP address using the ifconfig command.

ifconfig
eth0      Link encap:Ethernet  HWaddr 7a:bb:fe:fb:43:bc  
          inet addr:192.168.36.31  Bcast:192.168.36.255  Mask:255.255.255.0
          inet6 addr: fe80::78bb:feff:fefb:43bc/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:13967 errors:0 dropped:0 overruns:0 frame:0
          TX packets:7627 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:16228155 (16.2 MB)  TX bytes:715215 (715.2 KB)

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

That’s it, you are successfully configured static IP address for your ubuntu Machine.
