.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 scripts invoked by
.Pa /etc/rc
(see
.Xr rc 8 ) ,
and the shutdown scripts invoked by
.Pa /etc/rc.shutdown .
The
.Nm
file is a shell script that is sourced by
.Xr rc 8 ,
meaning that
.Nm
must contain valid shell commands.
.Pp
Listed below are the standard
.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.
Third party packages may test for additional variables.
.Pp
By default,
.Nm
reads
.Pa /etc/defaults/rc.conf
(if it is readable)
to obtain default values for various variables, and the end-user
may override these by appending appropriate entries to the end of
.Nm .
.Pp
.Xr rc.d 8
scripts that use
.Ic load_rc_config
from
.Xr rc.subr 8
also support sourcing an optional end-user provided per-script override
file
.Pa /etc/rc.conf.d/ Ns Ar service ,
(where
.Ar service
is the contents of the
.Sy name
variable in the
.Xr rc.d 8
script).
This may contain variable overrides, including allowing the end-user
to override various
.Ic run_rc_command
.Xr rc.d 8
control variables, and thus changing the operation of the script
without requiring editing of the script.
.Ss Variable naming conventions and data types
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 have boolean values (specified using
.Sq Ic YES ,
.Sq Ic TRUE ,
.Sq Ic ON
or
.Sq Ic 1
for true, and
.Sq Ic NO ,
.Sq Ic FALSE ,
.Sq Ic OFF
or
.Sq Ic 0
for false, with the values being case insensitive).
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
.Xr rc 8
expects to be set is not set, or the value is not one of the allowed
values, a warning will be printed.
.Ss Overall control
.Bl -tag -width net_interfaces
.It Sy do_rcshutdown
Boolean value.
If false,
.Xr shutdown 8
will not run
.Pa /etc/rc.shutdown .
.It Sy rcshutdown_rcorder_flags
A string.
Extra arguments to the
.Xr rcorder 8
run by
.Pa /etc/rc.shutdown .
.It Sy rcshutdown_timeout
A number.
If non-blank, use this as the number of seconds to run a watchdog timer for
which will terminate
.Pa /etc/rc.shutdown
if the timer expires before the shutdown script completes.
.It Sy rc_configured
Boolean value.
If false then the system will drop into single-user mode during boot.
.It Sy rc_fast_and_loose
If set to a non-empty string,
each script in
.Pa /etc/rc.d
will be executed in the current shell rather than a sub shell.
This may be faster on slow machines that have an expensive
.Xr fork 2
operation.
.Bl -hang
.It Em Note :
Use this at your own risk!
A rogue command or script may inadvertently prevent boot to multiuser.
.El
.It Sy rc_rcorder_flags
A string.
Extra arguments to the
.Xr rcorder 8
run by
.Pa /etc/rc .
.It Sy rc_directories
A string.
Space separated list of directories searched for rc scripts.
The default is
.Pa /etc/rc.d .
All directories in
.Ev rc_directories
must be located in the root filesystem, otherwise they will be silently
skipped.
.It Sy rc_silent
Boolean value.
If true then the usual output is suppressed, and
.Xr rc 8
invokes the command specified in the
.Va rc_silent_cmd
variable once for each line of suppressed output.
The default value of
.Va rc_silent
is set from the
.Dv AB_SILENT
flag in the kernel's
.Va boothowto
variable (see
.Xr boot 8 ,
.Xr reboot 2 ) .
.It Sy rc_silent_cmd
A command to be executed once per line of suppressed output, when
.Va rc_silent
is true.
The default value of
.Va rc_silent_cmd
is
.Dq twiddle ,
which will display a spinning symbol instead of each line of output.
Another useful value is
.Dq \&: ,
which will display nothing at all.
.El
.Ss Basic network configuration
.Bl -tag -width net_interfaces
.It Sy defaultroute
A string.
Default IPv4 network route.
If empty or not set, then the contents of
.Pa /etc/mygate
(if it exists) are used.
.It Sy defaultroute6
A string.
Default IPv6 network route.
If empty or not set, then the contents of
.Pa /etc/mygate6
(if it exists) are used.
.It Sy domainname
A string.
.Tn NIS
(YP) domain of host.
If empty or not set, then the contents of
.Pa /etc/defaultdomain
(if it exists) are used.
.It Sy force_down_interfaces
A space separated list of interface names.
These interfaces will be configured down when going from multiuser to singleuser
mode or on system shutdown.
.Pp
This is important for some stateful interfaces, for example PPP over ISDN
connections that cost money by connection time or PPPoE interfaces which
have no direct means of noticing
.Dq disconnect
events.
.Pp
All active
.Xr pppoe 4
and
.Xr ippp 4
interfaces will be automatically added to this list.
.It Sy hostname
A string.
Name of host.
If empty or not set, then the contents of
.Pa /etc/myname
(if it exists) are used.
.El
.Ss Boottime file-system and swap configuration
.Bl -tag -width net_interfaces
.It Sy critical_filesystems_local
A string.
File systems mounted very early in the system boot before networking
services are available.
Usually
.Pa /var
is part of this, because it is needed by services such as
.Xr dhclient 8
which may be required to get the network operational.
The default is
.Dq "OPTIONAL:/var" ,
where the
.Dq OPTIONAL:
prefix means that it's not an error if the file system is not
present in
.Xr fstab 5 .
.It Sy critical_filesystems_remote
A string.
File systems such as
.Pa /usr
that may require network services to be available to mount,
that must be available early in the system boot for general services to use.
The default is
.Dq "OPTIONAL:/usr" ,
where the
.Dq OPTIONAL:
prefix means that it is not an error if the file system is not
present in
.Xr fstab 5 .
.It Sy fsck_flags
A string.
A file system is checked with
.Xr fsck 8
during boot before mounting it.
This option may be used to override the default command-line options
passed to the
.Xr fsck 8
program.
.Pp
When set to
.Fl y ,
.Xr fsck 8
assumes yes as the answer to all operator questions during file system checks.
This might be important with hosts where the administrator does not have
access to the console and an unsuccessful shutdown must not make the host
unbootable even if the file system checks would fail in preen mode.
.It Sy no_swap
Boolean value.
Should be true if you have deliberately configured your system with no swap.
If false and no swap devices are configured, the system will warn you.
.It Sy swapoff
Boolean value.
Remove block-type swap devices at shutdown time.
Useful if swapping onto RAIDframe devices.
.El
.Ss One-time actions to perform or programs to run on boot-up
.Bl -tag -width net_interfaces

.Pa /var/account/acct
to exist.
.It Sy ccd
Boolean value.
Configures concatenated disk devices according to
.Xr ccd.conf 5 .
.It Sy cgd
Boolean value.

.Xr gpio 4
devices.
See
.Xr gpio.conf 5 .
.It Sy ldconfig
Boolean value.
Configures
.Xr a.out 5
runtime link editor directory cache.
.It Sy mixerctl
Boolean value.
Read
.Xr mixerctl.conf 5
for how to set mixer values.
List in
.Sy mixerctl_mixers
the devices whose settings are to be saved at shutdown and
restored at start-up.
.It Sy newsyslog
Boolean value.
Run
.Nm newsyslog
to trim logfiles before syslogd starts.
Intended for laptop users.
Passes
.Sy newsyslog_flags .
.It Sy per_user_tmp
Boolean value.
Enables a per-user
.Pa /tmp
directory.
.Sy per_user_tmp_dir

for additional details.
.It Sy quota
Boolean value.
Checks and enables quotas by running
.Xr quotacheck 8
and
.Xr quotaon 8 .
.It Sy raidframe
Boolean value.

.Xr raidctl 8
for additional details.
.It Sy rndctl
Boolean value.
Runs the
.Xr rndctl 8
utility one or more times according to the specification in
.Sy rndctl_flags .
.Pp
If
.Sy rndctl_flags
does not contain a semicolon
.Pq Ql \&;
then it is expected to contain zero or more flags,
followed by one or more device or type names.
The
.Xr rndctl 8
command will be executed once for each device or type name.
If the specified flags do not include any of
.Fl c , C , e ,
or
.Fl E ,
then the flags
.Fl c
and
.Fl e
are added, to specify that entropy from the relevant device or type
should be both collected and estimated.
If the specified flags do not include either of
.Fl d
or
.Fl t ,
then the flag
.Fl d
is added, to specify that the non-flag arguments are device names,
not type names.
.Pp
.Sy rndctl_flags
may contain multiple semicolon-separated segments, in which each
segment contains flags and device or type names as described above.
This allows different flags to be associated with different
device or type names.
For example, given
.Li rndctl_flags="wd0 wd1; -t tty; -c -t net" ,
the following commands will be executed:
.Li "rndctl -c -e -d wd0" ;
.Li "rndctl -c -e -d wd1" ;
.Li "rndctl -c -e -t tty" ;
.Li "rndctl -c -t net" .
.It Sy rtclocaltime

to the time zone information in the file
.Pa /etc/localtime .
.It Sy savecore
Boolean value.
Runs the
.Xr savecore 8
utility.
Passes
.Sy savecore_flags .
The directory where crash dumps are stored is specified by

Boolean value.
Run
.Xr tpctl 8
to calibrate touch panel device.
Passes
.Sy tpctl_flags .
.It Sy update_motd
Boolean value.

Read
.Xr veriexecctl 8
for more information.
.It Sy virecover
Boolean value.
Send notification mail to users if any recoverable files exist in
.Pa /var/tmp/vi.recover .
Read
.Xr virecover 8
for more information.
.It Sy wdogctl
Boolean value.

Passes
.Sy wdogctl_flags .
Refer to
.Xr wdogctl 8
for information on how to configure a timer.
.El
.Ss System security setting
.Bl -tag -width net_interfaces
.It Sy securelevel
A number.
The system securelevel is set to the specified value early
in the boot process, before any external logins, or other programs
that run users job, are started.
If set to nothing, the default action is taken, as described in
.Xr init 8
and
.Xr secmodel_securelevel 9 ,
which contains definitive information about the system securelevel.
Note that setting
.Sy securelevel
to 0 in
.Nm
will actually result in the system booting with securelevel set to 1, as
.Xr init 8
will raise the level when
.Xr rc 8
completes.
.It Sy permit_nonalpha
Allow passwords to include non-alpha characters, usually to allow
NIS/YP netgroups.
.It Sy veriexec_strict
A number.
Controls the strict level of Veriexec.
Level 0 is learning mode, used when building the signatures file.
It will only output messages but will not enforce anything.
Level 1 will only prevent access to files with a fingerprint
mismatch.
Level 2 will also deny writing to and removing of
monitored files, as well as enforce access type (as specified in
the signatures file).
Level 3 will take a step further and prevent
access to files that are not monitored.
.It Sy veriexec_verbose
A number.
Controls the verbosity of Veriexec.
Recommended operation is at level 0, verbose output (mostly used when
building the signatures file) is at level 1.
Level 2 is for debugging only and should not be used.
.It Sy veriexec_flags
A string.
Flags to pass to the
.Nm veriexecctl
command.
.El
.Ss Networking startup
.Bl -tag -width net_interfaces
.It Sy altqd
Boolean value.
ALTQ configuration/monitoring daemon.
Passes
.Sy altqd_flags .
.It Sy auto_ifconfig
Boolean value.
Sets the
.Sy net_interfaces
variable (see below) to the output of
.Xr ifconfig 8
with the
.Dq Li -l
flag and suppresses warnings about interfaces in this list that
do not have an ifconfig file or variable.
.It Sy dhclient
Boolean value.
Set true to configure some or all network interfaces using
the ISC DHCP client.
If you set
.Sy dhclient
true, then
.Pa /var
must be in
.Sy critical_filesystems_local ,
or
.Pa /var
must be on the root file system,
or you must modify the
.Sy dhclient_flags
variable to direct the DHCP client to store the leases file
in some other directory on the root file system.
You must not provide ifconfig information or ifaliases
information for any interface that is to be configured using the DHCP client.
Interface aliases can be set up in the DHCP client configuration
file if needed - see
.Xr dhclient.conf 5
for details.
.Pp
Passes
.Sy dhclient_flags
to the DHCP client.
See
.Xr dhclient 8
for complete documentation.
If you wish to configure all broadcast
network interfaces using the DHCP client, you can leave this blank.
To configure only specific interfaces, name the interfaces to be configured
on the command line.
.Pp
If you must run the DHCP client before mounting critical file systems,
then you should specify an alternate location for the DHCP client's lease
file in the
.Sy dhclient_flags
variable - for example, "-lf /tmp/dhclient.leases".
.It Sy dhcpcd_flags
Additional arguments to pass to
.Xr dhcpcd 8
when requesting configuration via
.Sy ifconfig_xxN
or
.Pa /etc/ifconfig.xxN .
.It Sy flushroutes
Boolean value.
Flushes the route table on networking startup.
Useful when coming up to multiuser mode after going down to
single-user mode.
.It Sy ftp_proxy
Boolean value.
Runs
.Xr ftp-proxy 8 ,
the proxy daemon for the Internet File Transfer Protocol.
.It Sy hostapd
Boolean value.

.Xr hostapd 8 ,
the authenticator for IEEE 802.11 networks.
.It Sy ifaliases_*
A string.
List of
.Sq Em "address netmask"
pairs to configure additional network addresses for the given
configured interface
.Dq *
(e.g.
.Sy ifaliases_le0 ) .
If
.Em netmask
is
.Dq - ,
then use the default netmask for the interface.
.Pp
.Sy ifaliases_*
covers limited cases only and considered unrecommended.
We recommend using
.Sy ifconfig_nnX
variables or
.Pa /etc/ifconfig.xxN
files with multiple lines instead.
.It Sy ifwatchd
Boolean value.
Monitor dynamic interfaces and perform actions upon address changes.
Passes
.Sy ifwatchd_flags .
.It Sy ip6mode
A string.
An IPv6 node can be a router
.Pq nodes that forward packet for others
or a host
.Pq nodes that do not forward .
A host can be autoconfigured
based on the information advertised by adjacent IPv6 routers.
By setting
.Sy ip6mode
to
.Dq Li router ,
.Dq Li host ,
or
.Dq Li autohost ,
you can configure your node as a router,
a non-autoconfigured host, or an autoconfigured host.
Invalid values will be ignored, and the node will be configured as
a non-autoconfigured host.
You may want to check
.Sy rtsol
and
.Sy rtsold
as well, if you set the variable to
.Dq Li autohost .
.It Sy ip6uniquelocal
Boolean value.
If
.Sy ip6mode
is equal to
.Dq Li router ,
and
.Sy ip6uniquelocal
is false,
a reject route will be installed on boot to avoid misconfiguration relating
to unique-local addresses.
If
.Sy ip6uniquelocal
is true, the reject route won't be installed.
.It Sy ipfilter
Boolean value.
Runs
.Xr ipf 8
to load in packet filter specifications from
.Pa /etc/ipf.conf
at network boot time, before any interfaces are configured.
Passes
.Sy ipfilter_flags .
See
.Xr ipf.conf 5 .
.It Sy ipfs
Boolean value.
Runs
.Xr ipfs 8
to save and restore information for ipnat and ipfilter state tables.
The information is stored in
.Pa /var/db/ipf/ipstate.ipf
and
.Pa /var/db/ipf/ipnat.ipf .
Passes
.Sy ipfs_flags .
.It Sy ipmon
Boolean value.
Runs
.Xr ipmon 8
to read
.Xr ipf 8
packet log information and log it to a file or the system log.
Passes
.Sy ipmon_flags .
.It Sy ipmon_flags
A string.
Specifies arguments to supply to
.Xr ipmon 8 .
Defaults to
.Dq Li -ns .
A typical example would be
.Dq Fl nD Pa /var/log/ipflog
to have
.Xr ipmon 8
log directly to a file bypassing
.Xr syslogd 8 .
If the
.Dq -D
argument is used, remember to modify
.Pa /etc/newsyslog.conf
accordingly; for example:
.Bd -literal
/var/log/ipflog  640  10  100  *  Z  /var/run/ipmon.pid
.Ed
.It Sy ipnat
Boolean value.
Runs
.Xr ipnat 8
to load in the IP network address translation (NAT) rules from
.Pa /etc/ipnat.conf
at network boot time, before any interfaces are configured.
See
.Xr ipnat.conf 5 .
.It Sy ipsec
Boolean value.
Runs
.Xr setkey 8
to load in IPsec manual keys and policies from
.Pa /etc/ipsec.conf
at network boot time, before any interfaces are configured.
.It Sy net_interfaces
A string.
The list of network interfaces to be configured at boot time.
For each interface "xxN", the system first looks for ifconfig
parameters in the variable
.Sy ifconfig_xxN ,
and then in the file
.Pa /etc/ifconfig.xxN .
If
.Sy auto_ifconfig
is false, and neither the variable nor the file is found,
a warning is printed.
Information in either the variable or the file is parsed identically,
except that, if an
.Sy ifconfig_xxN
variable contains a single line with embedded semicolons,
then the value is split into multiple lines prior to further parsing,
treating the semicolon as a line separator.
.Pp
One common case is to set
.Sy ifconfig_xxN Ns Li \&= Ns Qq dhcp ,
which will cause
.Xr dhcpcd 8
to be started for the interface.
Another common case it to set the
.Sy ifconfig_xxN
variable to a set of arguments to be passed to an
.Xr ifconfig 8
command after the interface name.
Refer to
.Xr ifconfig.if 5
for more details on
.Pa /etc/ifconfig.xxN
files, and note that the information there also applies to
.Sy ifconfig_xxN
variables (after the variables are split into lines).
.It Sy ntpdate
Boolean value.
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 .
Passes
.Sy ntpdate_flags .
.It Sy pf
Boolean value.
Enable
.Xr pf 4
at network boot time:
Load the initial configuration
.Xr pf.boot.conf 5
before the network is up.
After the network has been configured, then load the final ruleset
.Xr pf.conf 5 .
.It Sy pf_rules
A string.
The path of the
.Xr pf.conf 5
ruleset that will be used when loading the final ruleset.
.It Sy pflogd
Boolean value.
Run
.Xr pflogd 8
for dumping packet filter logging information to a file.
.It Sy ppp_peers
A string.
If
.Sy ppp_peers
is not empty, then
.Pa /etc/rc.d/ppp
will check each word in
.Sy ppp_peers
for a corresponding ppp configuration file in
.Pa /etc/ppp/peers
and will call
.Xr pppd 8
with the
.Dq call Sy peer
option.
.It Sy racoon
Boolean value.
Runs
.Xr racoon 8 ,
the IKE (ISAKMP/Oakley) key management daemon.
.It Sy rtsol
Boolean value.
Run
.Xr rtsol 8 ,
router solicitation command for IPv6 hosts.
On nomadic hosts like notebook computers, you may want to enable
.Sy rtsold
as well.
Passes
.Sy rtsol_flags .
This is only for autoconfigured IPv6 hosts, so set
.Sy ip6mode
to
.Dq Li autohost
if you use it.
.It Sy wpa_supplicant
Boolean value.
Run
.Xr wpa_supplicant 8 ,
WPA/802.11i Supplicant for wireless network devices.
If you set
.Sy wpa_supplicant
true, then
.Pa /usr
must be in
.Sy critical_filesystems_local ,
or
.Pa /usr
must be on the root file system.
.El
.Ss Daemons required by other daemons
.Bl -tag -width net_interfaces
.It Sy inetd
Boolean value.
Runs the
.Xr inetd 8
daemon to start network server processes (as listed in
.Pa /etc/inetd.conf )
as necessary.
Passes
.Sy inetd_flags .
The
.Dq Li -l
flag turns on libwrap connection logging.
.It Sy rpcbind
Boolean value.
The
.Xr rpcbind 8
daemon is required for any
.Xr rpc 3
services.
These include NFS,
.Tn NIS ,
.Xr rpc.bootparamd 8 ,
.Xr rpc.rstatd 8 ,
.Xr rpc.rusersd 8 ,
and
.Xr rpc.rwalld 8 .
Passes
.Sy rpcbind_flags .
.El
.Ss Commonly used daemons
.Bl -tag -width net_interfaces
.It Sy cron
Boolean value.
Run
.Xr cron 8 .
.It Sy ftpd
Runs the
