Translation(s): English


A daemon is a background process, also known as a service, usually started during the initial boot sequence by ?init. Daemons typically run independent of users, waiting for events to occur and providing services. Some common daemons include:

Daemons under Debian

Debian makes use of System V-style init scripts for daemon management, allowing daemons to run conditionally, based on the current RunLevel of the computer. For example, a daemon can be configured to run only when the computer is in single-user mode (runlevel 1) or, more commonly, when in multi-user mode (runlevels 2-5). For more information, see RunLevel.

Debian daemon configuration

Start, stop and reload daemons

The easiest way to manually (and temporarily) start, stop or reload a daemon is the run the following in a console or terminal as root:

# /etc/init.d/daemonname [stop|start|restart]

Controlling daemons in this manner is temporary and not survive a reboot. Refer to the next section to manage daemons on a more permanent basis.
