.Sh NAME
|
|
.Nm rc.conf
|
|
.Nd system startup configuration file
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
file specifies which services are enabled during system startup by
|
|
the startup script
|
|
.Pa /etc/rc .
|
|
The
|
|
.Nm
|
|
file is a shell script that is sourced by
|
|
.Pa /etc/rc
|
|
if it exists, meaning that
|
|
.Nm
|
|
must contain valid shell commands.
|
|
.Pp
|
|
Listed below are the
|
|
.Nm
|
|
variables that may be set, the values to which each may be set,
|
|
a brief description of what each variable does, and a reference to
|
|
relevant manual pages.
|
|
.Pp
|
|
Most variables are one of two types: enabling variables or flags
|
|
variables. Enabling variables, such as
|
|
.Sy inetd ,
|
|
are generally named after the program or the system they enable,
|
|
and are set to "YES" or "NO". Flags variables, such as
|
|
.Sy inetd_flags
|
|
have the same name with "_flags" appended, and determine what
|
|
arguments are passed to the program if it is enabled.
|
|
.Pp
|
|
If a variable that
|
|
.Pa /etc/rc
|
|
expects to be set is not set, or the value is not one of the allowed
|
|
values, a warning will be printed.
|
|
.Pp
|
|
Basic network configuration:
|
|
.Bl -tag -width net_interfaces
|
|
.It Sy hostname
|
|
Name of host.
|
|
If empty or not set, then the contents of
|
|
.Pa /etc/myname
|
|
(if it exists) are used.
|
|
.It Sy domainname
|
|
YP (NIS) domain of host.
|
|
If empty or not set, then the contents of
|
|
.Pa /etc/defaultdomain
|
|
(if it exists) are used.
|
|
.It Sy defaultroute
|
|
Default network route.
|
|
If empty or not set, then the contents of
|
|
.Pa /etc/mygate
|
|
(if it exists) are used.
|
|
.El
|
|
.Pp
|
|
One-time actions to perform or programs to run on boot-up:
|
|
.Bl -tag -width net_interfaces
|

.It Sy lkm
|
|
YES or NO. Runs
|
|
.Pa /etc/rc.lkm .
|
|
.It Sy savecore
|
|
YES or NO. Runs the

|
|
YES or NO. Updates the
|
|
.Nx
|
|
version string in the
|
|
.Pa /etc/motd
|
|
file to reflect the version of the running kernel. See
|
|
.Xr motd 5 .
|
|
.El
|
|
.Pp
|
|
Networking startup:
|
|
.Bl -tag -width net_interfaces
|
|
.It Sy ipfilter
|
|
YES or NO. Runs
|
|
.Xr ipf 8
|
|
to load in packet filter specifications from
|
|
.Pa /etc/ipf.conf
|
|
at network boot time, before any interfaces are configured. See
|
|
.Xr ipf 5 .
|
|
.It Sy auto_ifconfig
|
|
YES or NO. Sets the
|
|
.Sy net_interfaces
|
|
variable (see below) to the output of
|
|
.Xr ifconfig 8
|
|
with the
|
|
.Ar -l
|
|
flag and suppresses warnings about interfaces in this list that
|
|
do not have an ifconfig file or variable.
|
|
.It Sy net_interfaces
|
|
The list of network interfaces to be configured at boot time.
|
|
For each interface "xxn", the system first looks for ifconfig
|
|
parameters in
|
|
.Pa /etc/ifconfig.xxn
|
|
and then in the variable
|
|
.Sy ifconfig_xxn .
|
|
The contents of the file or the variable are handed to ifconfig
|
|
after the interface name. If
|
|
.Sy auto_ifconfig
|
|
is set to "NO" and neither the file nor the variable is found,
|
|
a warning is printed.
|
|
.It Sy ifaliases_*
|
|
List of
|
|
.Sq Ar "address netmask"
|
|
pairs to configure additional network addresses for the given
|
|
configured interface
|
|
.Dq *
|
|
(e.g.
|
|
.Sy ifaliases_le0 ) .
|
|
If
|
|
.Ar netmask
|
|
is
|
|
.Dq - ,
|
|
then use the default netmask for the interface.
|
|
.It Sy flushroutes
|
|
YES or NO. Flushes the route table on networking startup. Useful
|
|
when coming up to multiuser mode after going down to single-user
|
|
mode.
|
|
.It Sy ntpdate
|
|
YES or NO. Runs
|
|
.Xr ntpdate 8
|
|
to set the system time from one of the hosts in
|
|
.Sy ntpdate_hosts .
|
|
If
|
|
.Sy ntpdate_hosts
|
|
is empty, it will attempt to find a list of hosts in
|
|
.Pa /etc/ntp.conf .
|
|
