SSH isn't starting at boot on my server. When I try to set it to do that, systemd says it can't do that 'without a command.' What kind of command makes it happy? Where does it need to be? (I've futzed with the ssh file in /etc/default, even entered a command: (qwerty="42" -- it wasn't impressed). I looked around on the web (lots of info about systemd commands, but nothing about what I need.) Help?? -- Glenn English
