Copy the key to the other hosts. For this step please enter `vagrant` where a password is requested.
The option `-o StrictHostKeyChecking=no` tells it not to ask if you want to connect to a previously unknown host. Not best practice in the real world, but speeds things up here.
```bash
cat >> ~/.ssh/authorized_keys <<EOF
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD...OUTPUT-FROM-ABOVE-COMMAND...8+08b vagrant@master-1
EOF
ssh-copy-id -o StrictHostKeyChecking=no vagrant@master-2
ssh-copy-id -o StrictHostKeyChecking=no vagrant@loadbalancer
ssh-copy-id -o StrictHostKeyChecking=no vagrant@worker-1
ssh-copy-id -o StrictHostKeyChecking=no vagrant@worker-2
```
Now ssh to each of the other nodes and paste the above from your notepad at each command prompt.
For each host, the output should be similar to this. If it is not, then you may have entered an incorrect password. Retry the step.

Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'vagrant@master-2'"
and check to make sure that only the key(s) you wanted were added.
