You can't rely on system-config-services any more, as it does not
understand systemd native services.

For a basic check, just do 'ps aux | grep sshd', that'll tell you if
there's actually an sshd process running.

'systemctl status sshd.service' will tell you about the service: it
should say 'active (running)'. 'failed' or 'active (exited)' would be

systemctl has various other capabilities which can give you useful
information on services, see 'man systemctl', or the systemd website, or
lennart's blog, or lennart's posts to devel at ...

It means 1. But this is a generic message that's essentially just
s-c-services saying 'this is a systemd service and I don't know anything
about it'.  Not all systemd services are actually taking advantage of
systemd's socket activation feature yet - in fact, most of them aren't.
I think sshd is not using this feature, and it just runs on boot like it
did with sysv.
