Understanding your Linux daemons

Filed under
HowTos

A Unix daemon is a program that runs in the “background,” enabling you to do other work in the “foreground,” and is independent of control from a terminal. Daemons can either be started by a process, such as a system startup script, where there is no controlling terminal, or by a user at a terminal without “tying up” that terminal as the daemon runs. But which daemons can you safely play with? Which should you leave running?

An introduction to daemons

The real-world (i.e., non-computer) definition of “daemon” is either a spirit (an evil one) or an inner or private voice. It’s interesting to note that each of the real-world definitions actually does apply to Unix daemon programs. Like mythological daemons, Unix daemon programs skulk around unseen in the background just as a daemon would. And daemons act like an inner voice in that they can run continuously and, like a conscience, can always be accessed. The word “daemon” is one of those cases of chicken and egg computer acronyms in search of a definition and supposedly is based on “Disk And Execution MONitor” program.

Migrating to Linux: Network and System Settings

Linux gives you a lot of control over network and system settings. On your desktop, Linux lets you tweak just about anything on the system. Most of these settings are exposed in plain text files under the /etc directory. Here I describe some of the most common settings you’ll use on your desktop Linux system. A lot of settings can be found in the Settings program, and the available options will vary by Linux distribution. Usually, you can change the background, tweak sound volume, connect to printers, set up displays, and more. While I won't talk about all of the settings here, you can certainly explore what's in there. Read more
