I got a few questions about setting a static IP in Ubuntu JeOS. Here is a short and easy step by step guide!
The network settings are stored in the file /etc/network/interfaces and it’s always a good idea to make a backup first in case something goes wrong.
sudo cp /etc/network/interfaces /etc/network/interfaces.bak
When that is done we can safely edit the original file and can always look back or restore the old setting. Now edit the original file:
sudo nano /etc/network/interfaces
Find the part that says “# The primary netwok interface” and change that (and the following two lines) so it looks like this (change to your desired IP of course!):
# The primary network interface
iface eth0 inet static
Now save the file and restart the network with the following command:
sudo /etc/init.d/networking restart
Done! Now you’re JeOS should be on a static IP-address!
