Oh, I'm aware it's "boxes". But, I got into the "boxen" habit in the middle 90s and now that I'm "old" I've chosen to become stubborn and stuck in my ways. Also, I think it's more fun. I've got other things to be pedantic about.
OpenSSH on port 22 gets at least one attempt a minute for me (and that's with fail2ban blocking IPs on a single failure.) Dropbear on port 2222 gets at most one an hour.
On the other 20+ boxen with ssh on port xxx22 the logs and f2b rules are much smaller - which means less hassle for the admin.
And on the boxen with services behind WG there is zero noise.
Naturally we're using keys only with all this. The reduced noise in the logs/rules/firewall are very handy.
