System Services II

Summary:

• Annotated List of Common Services (a-h)

Annotated List of System Services (a-h)

This list tries to cover all the scripts in '/etc/init.d'.
It depends on your scale of installation how many of these services are available on your system.

In this list services are either 'optional', 'common' or 'essential'. 'Optional' means you can turn this service safely off without loosing vital functionality, 'common' means that this service isn't vital but usually enabled, and 'essential' means you should not turn it off, unless you know exactly what you are doing and why you are doing it.

acon

Needed for arabic languages to be displayed correctly.
Pertinence: Optional. Package: acon. Doc: Files in '/usr/share/doc/acon-{...}'

acpi

This service loads the kernel modules necessary for ACPI support. It reads the level of the machine's ACPI support from dmidecode and loads the appropriate modules. Without this service, you will not get basic ACPI support for things such as battery power monitoring. Pertinence: Common. Package: acpi. Doc: Files in /usr/share/doc/acpi-0.07.

acpid

ACPI (Advanced Configuration Power Interface) is the successor to APM (Advanced Power Management). 'acpid' is maintained by the ACPI4Linux project. acpid is a daemon for notifying userspace programs of ACPI events. Practically speaking, this allows you to invoke arbitrary programs or actions when events monitored by ACPI take place. These events include things like the machine going from AC to battery power (or vice versa), the battery charge dropping below a certain level, or the machine's lid being closed or opened.
Pertinence: Common. Package: acpid. Doc: manpage, files in /usr/share/doc/acpid-1.0.4.

adsl

amavisd-new is a high-performance and reliable interface between mailer (MTA) and one or more content checkers: virus scanners, and/or Mail::SpamAssassin Perl module. Pertinence: Optional. Package: amavisd-new. Doc: http://www.ijs.si/software/amavisd

amd

The Automounter Daemon. Useful for automatically mounting (hey1.1 ) network file systems or removable media. Since removable media are handled by 'udev' and 'hal' in Mandriva and 'amd' does have its handling quirks, you will possibly only need it for mounting network shares (NFS and the like). Do not run this if you don't need it as it poses a potential security hole.
Pertinence: Optional. Package: am-utils. Doc: MU on 'automount', man pages.

anacron

The cousin of the 'cron'-daemon. 'cron' runs tasks like system maintenance at certain times, but skips them if the system isn't running at that time. That's where 'anacron' comes in: it checks delayed 'cron'-tasks at boot-time and executes them. If your machine doesn't run all the time, you should leave it enabled.
Pertinence: Optional. Package: anacron. Doc:

man anacron

apcupsd

apcupsd manages UPS (Uninterruptable Power Supply) hardware manufactured by APC (American Power Conversion).
Pertinence: Optional. Package: apcupsd. Doc: The APCUPSD Users Manual

man arpd

arpwatch

Keeps track of MAC / IP address pairings. This is a useful security and adminstration tool for machines which act as DHCP servers. It can be used to keep track of clients requesting IP addresses for security or maintenance purposes, and can inform the administrator if the MAC address associated with a given IP address changes. If you do not run a machine acting as a DHCP server, you will not need this service.
Pertinence: Optional. Package: arpwatch. Doc:

man arpsnmp

authd

This daemon sits between a mailserver and the network. When someone attempts to send a mail to the mailserver, authd examines its rulebook and allows the mail through to the server, or not, accordingly. It used to be used for access control and as an impromptu spam filter. With the onset of more sophisticated spam filters like SpamAssassin and the introduction of access control within mailservers authd is becoming less used, although it still allows more fine grained access control than most mailservers do on their own. Pertinence: Optional. Package: authd. Doc: http://authd.org/docs

Httpd-naat is the special configured version for firewall use.
Pertinence: Optional. Package: apache-conf, httpd-naat. Doc:

man httpd

http-replicator

Replicator is a replicating HTTP proxy server.
