Configure network interface for direct connection

rated 0 times [ 3] [ 0] / answers: 1 / hits: 8419 / 1 Year ago, mon, november 28, 2022, 6:33:03

I need to connect two Ubuntu machines directly via ethernet (i.e., no switch or router between them).

One of them is running Ubuntu Desktop, so I am happy to use the network manager for that. The other one is using Ubuntu Core, so the configuration will need to be done in /etc/network/interfaces.

What is the appropriate configuration on each side?

The solution is to configure both sides as a static connection.

On the headless side in /etc/network/interfaces put:

auto eth0

iface eth0 inet static

    address 192.168.1.100

    gateway 192.168.1.254

    netmask 255.255.255.0

On the Ubuntu desktop side, configure a static connection in the network-manager, but with a different address (in the same network range).
