I want to gather the host keys but ssh-keyscan command is not found on my linux. Anyway to achieve the same with some other commands without adding this command explicitly.

I am running with Wind River Linux 8.0.

  • You might be able to do something like ssh -o StrictHostKeyChecking=no -N $hostname for each host, and then pull all the keys out of ~/.ssh/known_hosts – Patrick Jan 23 '18 at 13:26

You may check before which keys are available via ssh <host> -Q key-plain. At least you can gather the host key in a visualized way via ssh <host> -o VisualHostKey=yes. I am not sure if this is reversible.
