Enable SSH Service on NixOS

You can check if SSH port is opened once you login to your NixOS vm;

Check if SSH daemon is enabled;

grep ssh /etc/nixos/configurations.nix

Sample output;

# services.openssh.enable = true;

As you can see, it is disabled.

So, to enable SSH service on NixOS, edit the /etc/nixos/configurations.nix configuration file;

sed -i '/openssh/s/#//' /etc/nixos/configurations.nix

Confirm the enablement;

grep ssh /etc/nixos/configurations.nix

Sample output;

services.openssh.enable = true;

Apply the changes;

sudo nixos-rebuild switch

Once the changes are applied, SSH service should now be running.

Check status;

systemctl status sshd
