Logging in to 100 server to test my account
I have been logging to 100 server everyday to test if I can login to the server.
I created a script to ssh-copy-id to every host so next time it will be password less. Now it keeps prompting me

Are you sure you want to continue connecting (yes/no)? yes

This is normal for first time login. Any way?
To automate?

Can you please provide more context on this use case?
Just to ensure that you are able to login to 100s of servers are you logging in everyday? Any other reason?

I have the same logging into a host with dynamically changing IP address:
Code:
The authenticity of host '[nn.nnn.nn.nnn]:22 ([nn.nn.nn.nnn]:22)' can't be established.
ECDSA key fingerprint is SHA256:fQRh1WeU0OYV0qK+nRdYKacsE5..............
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '[nn.nnn.nn.nnn]:22' (ECDSA) to the list of known hosts.

The second+ logins to the same IP work without interaction, as the host key is known.

This is a scurity feature! Be very sure what you are doing when circumventing it with the StrictHostKeyChecking=no option!
