    Eh, those attempts are just noise anyway. Use proper pubkey auth instead of normal passwords and you’ll be fine. Any key size is probably enough to prevent successful bruteforce attacks. Anything above 2048 and there’s basically no chance for them to guess right within several years of constant trying. Most bots move along quickly as well, they try their predefined list of (common usernames) x (common passwords) and that’s it.

    Install endlessh, an ssh tar pit, if you want to make their lives a little more annoying. Use a non-standard port if your OCD can’t stand the slowly filling auth attempt logs.
