Platform engineering, Kubernetes and other notes from the trenches
You’ve just set up a VPS. A few days in, out of curiosity, you check what SSH has been up to: $ systemctl status sshd â—Ź ssh.service - OpenBSD Secure Shell server Active: active (running) since Sat 2026-04-12 09:14:03 UTC ... Apr 12 17:03:11 lpsz sshd[1432]: Failed password for root from …
