I have just installed tor:
sudo apt-get install tor.
After that, I rebooted and ran
sudo systemctl status tor and noticed that it is active running. So I suppose it is enable by default. How to setup it in such a way that it will only run when I
sudo systemctl start tor
Edit: I don't agree marking this question as duplicate of this since my question is about
Systemd and the allegedly duplicate is in
SysVinit. The way to enable/disable services is clearly difference between both.
