.Sh NAME
.Nm intro
.Nd introduction to system maintenance and operation commands
.Sh DESCRIPTION
The manual pages in section 8 contain information related to
system operation and maintenance.
They describe commands concerning file systems,
such as
.Xr fsck 8 ,
.Xr mount 8 ,
and
.Xr newfs 8 .
.Pp
There are pages which document the running of the system, such as
.Xr afterboot 8 ,
.Xr ifconfig 8 ,
.Xr security 8 ,
and the configuration files located in
.Pa /etc .
Procedures concerning system failure are documented in
.Xr crash 8 .
.Pp
Section 8 pages also describe network services and daemons.
The rest of this page discusses some of the main daemons
available on the FabBSD system, and how to enable/disable them.
.Pp
System daemons are controlled by the script
.Xr rc 8 ,
which is in turn configured by
.Xr rc.conf 8 .
For example the CNC machine control daemon
.Xr machctld 8
is controlled by the following line from
.Xr rc.conf 8 :
.Bd -literal -offset indent
.Dl machctld_flags=NO
.Ed
.Pp
Thus it is not started by default.
To enable or disable daemon processes,
administrators should edit the file
.Xr rc.conf.local 8 ,
which overrides
.Xr rc.conf 8 .
So to enable
.Xr machctld 8 ,
the following line might be added to
.Pa /etc/rc.conf.local :
.Bd -literal -offset indent
machctld_flags=""
.Ed
or
.Bd -literal -offset indent -compact
machctld_flags="-b localhost"
.Ed
.Pp
As can be seen above,
this method is also used to specify additional options.
.Pp
Below is a list of some of the daemons available.
For further information, see
.Xr rc 8
and the individual pages for the utilities.
.Ss Automounter daemon (amd)
If using the
.Xr amd 8
package,
go into the
.Pa /etc/amd
directory and set it up by
renaming
.Pa master.sample
to
.Pa master
and editing it and creating other maps as needed.
.Pp
Relevant
.Xr rc.conf 8
variables:
.Va amd ,
.Va amd_dir ,
and
.Va amd_master .
.Ss Clock synchronisation
In order to make sure the system clock is correct,
it may be synchronised with a number of external sources.
The utility available is
.Xr rdate 8 .
.Pp
Relevant
.Xr rc.conf 8
variables:
.Va rdate_flags .
.Ss Concatenated disks (ccd)
If you are using
.Xr ccd 4
concatenated disks, edit
.Pa /etc/ccd.conf .
Use the
.Ic ccdconfig -U
command to unload and the
.Ic ccdconfig -C
command to create tables internal to the kernel for the concatenated disks.
You then
.Xr mount 8 ,
.Xr umount 8 ,
and edit
.Pa /etc/fstab
as needed.
.Ss NFS server
If this is an NFS server,
edit
.Pa /etc/exports .
.Pp
Relevant
.Xr rc.conf 8
variables:
.Va nfs_server
and
.Va nfsd_flags .
.Ss RPC-based network services
Several services depend on the RPC portmapper,
.Xr portmap 8 ,
being running for proper operation.
This includes NFS exports, among other services.
.Pp
Relevant
.Xr rc.conf 8
variables:
.Va portmap .
