How can I list all enabled services from systemctl?
I know running systemctl command by itself lists all services, but I would like to only get the enabled ones.
I read about how to enable and disable services in Ubuntu and it seems that there are different possibilities to manage them.
The first method I found is update-rc.d to add new services to startup, which aims on the /etc/init.d folder and its contents.
The other one I found is to edit .conf files in the /etc/init folder.
What's the recommended way to enable / disable / add services and why?
Could you please give a short bulletproof step by step example on how to add a service in Ubuntu and enable and disable it?
I have a daemon that runs fine if I start it manually with the service command:
ricardo@ricardo-laptop:~$ sudo service minidlna start
* Starting minidlna minidlna [ OK ]
but it's not configured to auto start when the PC reboots.
How can I configure it to start automatically, even if no one is logged into the PC?
I switched from SLES to Ubuntu and now I want to restart my local server. In SLES I used:
