Personal Fedora Core 4 Installation Guide

[quote]
To see what services you have running:

[root@charon ~]# service –status-all | grep running

Also you can use ‘chkconfig’ (replace 3 with 5 for runlevel 5):

[root@charon ~]# chkconfig –list | grep 3:on

Run ‘serviceconf’, edit running services for runlevel 5 *AND* 3,
do not touch the others.

Be careful, do not disable things that you’re not sure if need or
if you do not understand or know what they are.

Note: The following are either the most popular services or the
services and daemons that were enabled by default on my installation.

apmd
    Is used by some laptops. If your computer supports ACPI, then ‘apmd’
    is probably not needed.
auditd
    This saves audit records generated by the kernel. Not sure how this
    information is used. For now I have this enabled.
autofs
    This mounts removable disks (such as USB harddrives) on demand. I highly
    recommend keeping this enabled.
bluetooth, hicd, sdpd
    Bluetooth is for portable local wireless devices (NOT wifi,802.11). Some
    laptops come with bluetooth support. I have no bluetooth devices.
cron, atd, anacron
    These are schedulers, it is recommended you keep at least 1 (cron)
    running, especially if you keep your computer running for long periods
    of time. If you are running a server look into which schedulers you require.
cpuspeed
    Changes your CPU speed to save power. Many laptop CPU’s might use this.
    (Pentium-M, AMD PowerNow, Transmetta, Intel SpeedStep, Athlon-64?)
cupsd, cups-config-daemon
    Used for printing. Allow these only if you have CUPS compatible printer
    that works in Fedora.
gpm
    This is the console mouse pointer (no graphics).
    Leave enabled for runlevel 3, but probably not needed for runlevel 5.
iptables
    This is the standard Linux software firewall. Learn to set this up if
    you are directly connected to internet. Not needed if you use a hardware
    firewall (D-Link, Netgear, Linksys, etc).
isdn
    Another form of internet connect service/hardware. I do not use this hardware.
kudzu
    This runs the hardware probe, and optionally configures changed hardware.
    If you swap hardware or need to detect hardware you can leave this enabled,
    however if you do not, you can disable this and run it only when necessary.
lm_sensors
    This monitors motherboard sensor values useful for watching realtime values
    for PC health, etc. This is also popular with ‘GKrellM’ users.
    More information on lm_sensors homepage.
    I personally do not find this valuable or necessary.
mDNSResponder, nifd, autoipd
    This is part of zeroconf and is useful for detecting devices
    and their names on local network without a DNS server.
    Some devices support this feature as well as Apple OS X.
    Although this is getting more popular, I do not use this on my network.
mdmonitor
    I do not have a Software RAID.
messagebus
    This is an IPC (Interprocess Communication) service for Linux.
    I highly recommend leaving this enabled.
netfs
    This is used for automatic mounting of any shared network file space
    such as NFS, Samba, etc on bootup. Useful if you connect to another server
    your network. I have this disabled.
nfs,nfslock
    I do not use NFS. This the standard network file sharing for Unix/Linux/BSD.
ntpd
    Automatically updates system time from the internet.
    Mentioned in the installation process.
pcmcia
    Removable slot hardware support used primarily on laptops.
rhnsd
    Service to inform you of updates from Redhat/Fedora. I only update sparingly
    when necessary. I have this disabled.
rpcgssd, rpcidmapd, rpcsvcgssd
    Used for NFS v4. If you do not have other Unix/Linux machines this unneeded.
sendmail
    Most people do not need a mail transport agent. If you check your mail
    on the web (hotmail/yahoo) or you use a mail program (imap/pop) in Thunderbird,
    Mozilla, Kmail, Evolution, etc. then you do not need sendmail.
sshd
    SSH allows other people to log into your computer from another computer
    on your network. This is not needed if you have no other computers or no
    need to login from a remote location (work etc.).

DO NOT DISABLE THE FOLLOWING (unless you know what you are doing).

acpid, haldaemon, messagebus, klogd, network, portmap, syslogd, xinetd
