In RedHat distributions like RHEL, Fedora and also CentOS you have a tool called ntsysv to manage daemons and their runlevels. In Debian there is an alternative tool that lets you determine what daemon you want to run using a text GUI
It makes it easy to manage which daemons you would like to run like telnet, ssh etc.
If the tool isn’t installed, install it by running the command
apt-get install sysv-rc-conf
