chkconfig(1M)chkconfig(1M)NAMEchkconfig - configuration state checker
SYNOPSISchkconfig [ -s ]
chkconfig [ -f ] flag [ on | off ]
DESCRIPTIONchkconfig with no arguments or with the -s option prints the state (on or
off) of every configuration flag found in the directory /var/config. The
flags normally are shown sorted by name; with the -s option they are
shown sorted by state.
A flag is considered on if its file contains the string ``on'' and off
If flag is specified as the sole argument, chkconfig exits with status 0
if flag is on and with status 1 if flag is off or nonexistent. The exit
status can be used by shell scripts to test the state of a flag. Here is
an example using sh(1) syntax:
if /sbin/chkconfig verbose; then
echo "Verbose is on"
echo "Verbose is off"
The optional third argument allows the specified flag to be set. The
flag file must exist in order to change its state. Use the -f
(``force'') option to create the file if necessary.
These flags are used for determining the configuration status of the
various available subsystems and daemons during system startup and during
A daemon or subsystem is enabled if its configuration flag in the
/var/config directory is in the on state. If the flag file is missing,
the flag is considered off. The following is a list of available flags
and the associated action if the flag is on. Depending upon your
configuration, they may not all be available on your system.
4DDN Initialize 4DDN (DECnet connectivity) software.
acct Start process accounting.
auto_ipaddress Enable dynamic host configuration protocol (DHCP) as a

autofs Start the NFS autofs daemon. Only one of the pair autofs
and automount should normally be enabled.
automount Start the NFS automounter daemon.
desktop If off, fewer of the IRIX Interactive Desktop(TM) user
interface features are enabled, and typically a different
toolchest menu is used. It is identical to creating the
file $HOME/.disableDesktop except that it applies to all
accounts. The specific effect is that the desktop
version of Xsession (/usr/lib/X11/xdm/Xsession.dt) is not
run upon login, and therefore programs started from that
file are not run or are run with different options.
fontserver Start the X11R6 font server daemon. See xfs(1).
gated Start the Cornell routing daemon instead of the BSD

Japanese Language Module is installed.
lockd Start the NFS lock and status daemons.
mediad Start the removable media daemon.
miser Start the miser daemon.
mrouted Start the IP multicast routing daemon (useful only on
named Start Internet domain name server.
network Allow incoming and outgoing network traffic. This flag
can be set off if you need to isolate the machine from
the network without removing cables.
nfs Enable NFS operations: start rpc.lockd and biod daemons,
mount all NFS filesystems, start autofs or automounter.
nfsd Start NFS serving: export entries from /etc/exports,
start the NFS daemons rpc.mountd and nfsd. Requires that
nfs flag is set to ``on''.
noiconlogin Do not show user icons on the login screen.
nsr Start up the IRIS NetWorker daemons. See nsr(1M) for
nostickytmp Do not turn the sticky bit on for the directories /tmp
pam Enable PAM in the system. See pam(8) for more details.
pcnfsd Start the PC-NFS server daemon.
pmcd Start the Performance Metrics Collector Daemon. See
pmcd(1) for more details.
pmie Start the Performance Metrics Inference Engines. See
pmie(1) and pmie_check(1) for more details.
privileges Enable privileges to be used on the system. See
runpriv(1M) and privilege(4) for more details.
quotacheck Run quotacheck(1M) on the filesystems that have quotas
enabled. See quotas(4) for more details.
quotas Enable quotas for local configured filesystems.
rarpd Start the Reverse ARP daemon.
routed Start the 4.3BSD RIP routing daemon. See routed(1M) for
rsvpd Start the RSVP daemon. See rsvpd(1M) for more details.
rtnetd Initialize preemptable networking for real-time use.
rwhod Start the 4.3BSD rwho daemon.
sar Start the system activity reporter.
savecore Enable the saving of kernel crash images. Some
information is saved in /var/adm/crash even if saving is
disabled. See savecore(1M) and icrash(1M).
snmpd Start the Simple Network Management Protocol daemon.
soundscheme Start the IRIX Interactive Desktop audio cue daemon.
timed Start the 4.3BSD time synchronization daemon.
timeslave Start the Silicon Graphics time synchronization daemon.
verbose Print the names of daemons as they are started.
videod Enable the video daemon. Used by video devices such as
vswap Add virtual swap. See swap(1M) for a discussion of
virtual swap. By default 80000 blocks are added. You
can increase or decrease this amount by modifying the
visuallogin Enable the visual login screen.
windowsystem Start the X window system. If windowsystem is off, it is
necessary to modify the inittab(4) file to enable
getty(1M) on the textport window if you wish to use
graphics as a dumb terminal.
The recommended means of enabling and disabling the
window system are the commands startgfx(1G) and
xinerama Enable Xinerama extension of the X server. See Xsgi(1)
and Xinerama(3X) for more details.
xdm Start the X display manager.
xlv Start the daemons for xlv logical volumes optional
yp Enable NIS, start the ypbind daemon.
ypmaster If yp is on, become the NIS master and start the passwd
server. The ypserv flag should be on too.
