The previous commit hedged on the ban policy because I thought fail2ban was not
installed here. It is — the earlier ubuntu-setup run installed it — so the claim
could be checked rather than remembered.
Checked, and it was right: /etc/fail2ban/jail.d/defaults-debian.conf ships
`[sshd] enabled = true`, and the running jail reports maxretry 5, findtime 600,
bantime 600. This host has banned 6 addresses already.
