Disabling unnecessary Services in fedora

I tell you what services are necessary for running linux ( fedora )

Code:: [b] Network Manager[/b] NetworkManager is service (with additional tools) meant to automate management of both network devices and network connections. Many laptop users who switch between Wireless WiFi connections and/or Wired Ethernet connections may find this useful. Fedora 10 has this enabled by default. If your connections work properly then you can leave this default. If however you have problems or you prefer the previous network service, then disable NetworkManager and enable the network service. Note that you should make sure your network settings are correct either via system-config-network for the network service, and/or nm-connection-editor for NetworkManager. Servers/desktops with fixed IP's may prefer network service.

Code:: [b] acpid [/b] Advanced Configuration and Power Interface daemon which controls and allows interfacing to power management and certain input devices. It is recommended to be enabled only if you need it. If you are running a modern graphical desktop (GNOME, KDE) then many ACPI functions should be supported with the acpid daemon. Test disabling it, if you have power management issues (suspend, sleep, wakeup) then re-enable it. If you run without graphics (i.e. runlevel 3) you may find this service necessary for ACPI functions.

Code:: [b] anacron , cron , atd [/b] These are schedulers with each having slightly different purposes. It is recommended you keep the general purpose scheduler cron enabled, especially if you keep your computer running for long periods of time. If you are running a server look into which schedulers you require. Most likely atd and anacron should be disabled for desktops/laptops.

Code:: [b] auditd [/b] This saves audit records generated by the kernel. This information can be used in different ways. SELinux uses the audit daemon to record events. While there are other logging services it is recommended you leave this enabled (especially for users with SELinux enabled).

Code:: [b] avahi deamon [/b] Avahi is an implementation of zeroconf and is useful for detecting devices and services on local network without a DNS server. This is also the same as mDNS. Most users may have this disabled.

Code:: [b] cpuspeed [/b] This throttles your CPU runtime frequency to save power. Many modern laptop CPU's support this feature and now most new desktops support this. Users should enable only if they are users of Pentium-M, Centrino, AMD PowerNow, Transmetta, Intel SpeedStep, Athlon-64, Athlon-X2, Intel Core 2 hardware. Laptop users are highly recommended to leave this enabled. Disable this if you want your CPU to remain at a fixed state.
