Welcome to the Linux Foundation Forum!
Exercise 5.5: Parallel ssh command execution
In the solution step 2 you have the following text:
- Setup ssh keys and fingerprints If not already done, create a key pair on the local machine
Copy the key to the remote and save the fingerprint
$ ssh-copy-id localhost
I don't understand why in the command the host is 'localhost' although in the text above is mentioned "copy the key to the remote...". Please explain why is that?
