How do I harden my sshd_config to allow only 1 user to be remotely logged in at any given time? (A non-admin/wheel and not-root user will login remotely, then upgrade (ie. "su -l admin) to admin/wheel, and then to root should be counted as the same user being logged in at any given time.) I...

I have a concern about the recent news regarding the newly discovered SSH attacks, when "ChaCha20-Poly1305" or "CBC with Encrypt-then-MAC" is used. So, if we set up a server (sshd) or using it as a client (ssh) as default, would this vulnerability be relevant?
