I am attempting to ssh into an intel NUC mini computer from my laptop. They are connected directly using a Cat5e ethernet cable. Both systems are running Ubuntu 18.04. I have tried setting static IP addresses on both computers but I am not getting any response when I try to ping the NUC.

Here is my /etc/netplan/01-network-manager-all.yaml file on the NUC:

network:

  version: 2

  renderer: networkd

  ethernets:

    eno1:

      dhcp4: no

      addresses: [192.168.1.150/24]

      nameservers:

        addresses: [8.8.8.8,8.8.4.4]

And here is my /etc/netplan/01-network-manager-all.yaml file on my laptop:

network:

  version: 2

  renderer: networkd

  ethernets:

    enp2s0:

      dhcp4: no

      addresses: [192.168.1.151/24]

      nameservers:

        addresses: [8.8.8.8,8.8.4.4]

I am then configuring both networks by running:

sudo netplan apply

And then pinging the NUC with:

ping 192.168.1.150

Am I configuring this wrong? I also know that there is a way to ssh between these two computers by setting up a DHCP server on the NUC along with a static IP address and then I wouldn't have to set up the static IP address on the laptop as well. If anyone has any ideas on how to do this please let me know!

UPDATE: I got it to work using static IP addresses on both computers. Next I would like to know if there is a way to do this without needing to set the static IP address on the laptop because there will be multiple computers logging into the NUC at different times. I know there is a way to do this with a DHCP server on the NUC and was wondering if anyone knows how to set that up? Thanks everyone for all of your help!

I finally got it to work. I changed my setup back to the original configuration to use NetworkManager and used the /etc/network/interfaces files for configuration.

This is what my /etc/network/interfaces file looks like for the laptop with ethernet port enp2s0:

auto enp2s0 

iface enp2s0 inet static 

address 192.168.1.151 

netmask 24 

This is what my /etc/network/interfaces file looks like for the NUC with ethernet port eno1:

auto eno1 

iface enp2s0 inet static

address 192.168.1.150

netmask 24 

I also used the following to reboot the interface and enable connection:

sudo ifdown enp2s0 && sudo ifup enp2s0

Then, I can see the connection is working by running ping 192.168.1.150 on the laptop. Thanks for all the help!

Actually you can set you network using legacy way - by editing /etc/network/interfaces. First you need to list all your interfaces by ip a. Then, you need to edit network file on both machines. It should look like that:

name of your interface* auto iface



name of your interface* inet static



address 192.168.1.xxx



netmask 24

Then you can do ip link set name of your interface down && ^down^up

That will reboot you interface and enable configuration.
