For Slaves

You must install openssh-server to slave machines.

$ sudo apt-get install openssh-server

Then, restart sshd service

$ sudo systemctl restart sshd

If slave machine user is not root, you must give privileges like 'sudo'

$ echo "<slave_machine_user> ALL = NOPASSWD : ALL" >> /etc/sudoers

You must be carefull, if your machine doesnt have root user.

For Master

Generate ssh key

$ ssh-keygen

Copy ssh key to slave machines

$ ssh-copy-id -i <slave_machine_name>@<slave_machine_ip>

sign_and_send_pubkey: signing failed: agent refused operation

$ ssh-add
$ ssh-add -l

Then connect

ssh <slave_machine_name>@<slave_machine_ip>
