Whisper four. Knuckles still intact?

Hint:
There is no interactive shell. You can knock with a remote command
(ssh … uptime) or with a bare login (ssh …). Either way works for the door.

This place is not a lounge. State your business and leave.

If your client is too fancy about host keys: this door only offers
* rsa-sha2-512
* rsa-sha2-256
* ssh-rsa

Your own login key can be newer. The lock on the building is old.

See you inside.
