I installed the
openssh-server package but only want it to start on demand, as opposed to boot which is the package default.
When I tried to disable the SSH server using upstart I got the following output and warning
sudo update-rc.d ssh disable update-rc.d: warning: start runlevel arguments (none) do not match ssh Default-Start values (2 3 4 5) System start/stop links for /etc/init.d/ssh do not exist.
Is this something to be concerned about? Should I be using another method? Best I can tell Freya is based on Ubuntu 14.04 which was still using upstart as the service management system.
