Getting ready

As with the previous section, confirm that both of your Vagrant boxes are enabled and connect to the first using the vagrant command:

[vagrant@centos1 ~]$ ls .ssh/authorized_keys  config  id_ed25519  id_ed25519.pub  known_hosts

Copy your key to centos2 if you haven't already, accepting the host key if you need to:

[vagrant@centos1 ~]$ ssh-copy-id 192.168.33.11/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/vagrant/.ssh/id_ed25519.pub"/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed/usr/bin/ssh-copy-id: INFO: ...
