Set A Static IP Address On Ubuntu 10.10 Maverick Meerkat From The Command Line

By Jonathan Moeller - Last updated: Friday, October 29, 2010 - Save & Share - 6 Comments

It is not intuitively obvious how to assign Ubuntu 10.10 Maverick Meerkat a a static IP address from the

command line. However, much of Linux administration involves the editing of text files, and assigning a static

IP address is no different. Youll need to edit the following file:

/etc/network/interfaces

Initially, the file only contains information about your local loopback address:

auto lo

iface lo inet loopback

To assign a static IP address, youll need to make some changes to this file.

Lets say you want to assign a static IP of 192.168.1.2 to your eth0 network connection (the first Ethernet




4/6

adapter on your system; if you only have one, it will be eth0), with a subnet mask of 255.255.255.0 and a

local gateway of 192.168.1.1. First, make a backup copy of the interfaces file:

sudo cp /etc/network/interfaces ~

This will make a backup copy in your home directory in case something goes amiss during the editing

process. Next, fire up a text editor:

sudo vi /etc/network/interfaces

(Obviously you can substitue emacs or your editor of choice.)

Once the file is open, add the following lines:

auto eth0

iface eth0 inet static

address 192.168.1.2

netmask 255.255.255.0

gateway 192.168.1.1

Once youve added these lines, save the interfaces file to disk, and exit your text editor. If you want to add a

static DNS server, youll need to edit the /etc/resolv.conf file with this command:

sudo vi /etc/resolv.conf

To set a static DNS server with the address of 192.168.1.10, add this line to the file:

nameserver 192.168.1.10

Save the file, and exit your text editor.

Youll then to need have your system load the new IP configuration. You can do that by rebooting, but if that

takes too long, you can use these two commands to force Ubuntu to re-read the configuration files:

sudo ifdown eth0

sudo ifup eth0

Your system will then have a static IP address.

didnt work.

Please help!!! I have a backup of it but dont know how to restore it.

Sincerely,

Wrightrl

Comment from Jonathan Moeller


Copy the backup over this file:

/etc/network/interfaces

And then use these commands to reset the eth0 interface:

sudo ifdown eth0

sudo ifup eth0

Comment from .


you forgot to add auto eth0

should read

auto eth0

iface eth0 inet static

address 192.168.1.2

netmask 255.255.255.0

gateway 192.168.1.1

How do i find the IP i am going to use to access the server from outside my network?

Comment from Jeramy


I am new to linux so it is possible that i did something wrong, but I tried this but got an error ifdown: interfaceeth0 not configured until I did a sudo /etc/init.d/networking restart (which I found in another document from a

google search) then the ifdown and ifup worked fine.
