[TUTORIAL NEWBIE] How to set static ip in Ubuntu

Hi, with this basic tutorial, i will show you, how set a static ip address in Ubuntu.

To configure your Udoo board to use a static ip address assignment, we add the static method to the inet address family statement for the appropriate interface in the file /etc/network/interfaces.

Confirm your network interface name using below command,normally it’s eth0.

Code:

ifconfig -a

Open network configuration file use below command.

Code:

sudo nano /etc/network/interfaces

Remove the line (if have).

Code:

iface eth0 inet dhcp

Append below lines.

Code:

iface eth0 inet static
address 192.168.1.103
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

Ctrl+O for save, then Ctrl+X for exit.
Restart networking service to enable the change.

Code:

sudo /etc/init.d/networking restart

 

Hi,

I tried the above step when I am connected via WiFi, SSH.

When I issue the restart command UDOO reply;

ubuntu@udoo:~$ sudo /etc/init.d/networking restart
* Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces
* Reconfiguring network interfaces...

I tried to do the same with root user, result the same, when I force restart the LAN is disconnected.

Please advice

I'm interested to hear how setting a static IP has been working out for other people, as I've been having real trouble. I've done it many times before on servers and Rasberry Pi's but for some reason on the Udoo it fails everytime, and I lose all connectivity.

ifconfig -a tells me that my ethernet is 'eth6' which seems a little odd as I would have expected 'eth0'

How has this worked for other people?

 

The Ubuntu image uses eth6 , but the debian image uses eth0 , so it can`t be uboot setting it.
I tried to fix that , but had so many other problem I just moved to Debain.

 

Someone knows a solution that works ?
It doesn't work for me and I really need it...
I use a Neo Basic Board with Ubuntu

 

I did not try this myself (I set the static IP through my router, much safer)

There is a bug (feature?) in 14.04 where “service networking start|stop|restart” does nothing. This command/script worked in 13.10/13.04/12.04, however it doesn’t work in 14.04. To revert back to the 13.10 networking scripts go to https://github.com/metral/restore_networking

Thank you watervl, I found another way which works but your informations could be helpful

 

What was that other way you used? That could also be helpful for the next one with this question.

 

It's an empirical way, but it's works for me ( and I don't know why ) :
I followed this Raspberry pi tuto (which I'm familiar with) to found gateway address and network address (assuming I work with a box-router) :
so I hit the following command :
netstat -nr
Which gave me
gateway : 192.168.0.1
network : 192.168.0.0 ( what is strange because my router address is 192.168.0.1, the same as gateway)
And I put on the /etc/network/interfaces/ file :
auto eth0
iface eth0 inet static
address 192.168.0.83
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1

And I really don't know why, but...it works
