Guys, I have not tested this command on my Ubuntu 20.04.2 so excuse me. I see this article is a bit old.
I have been using systemctl now as SystemD replaced SystemV. Is still valid? Well, the easiest way to find out is to go to the terminal but my CPU fan is not cleaned lately and my laptop overheated so it’s off now.
And BTW I wanted to “buy you a coffee” but Stripe ( do not have a PayPal account ) refuses payments from the EU to India.
I did not try on your site but on another one more than 5 times.
Is the run level 0 and 6 require for service?
Ex: chkconfig level 02356 servicename on
May I know the reason for 0 and 6 levels to assign the particular service.
Thanks Regards,

No only run level 3 and 5 required for service to auto start and run…
wrong path has been gives, please correct it to /etc/rc.d/init.d/
Sir, I need to know the way to find out the service name and daemon name for a particular package. Example for samba package alone, it has to show the service name smb and daemon name smbd.
