RC.CONF(5) File Formats Manual RC.CONF(5)
NAME
rc.conf - system startup configuration file
DESCRIPTION
The rc.conf file specifies which services are enabled during system
startup by the startup scripts invoked by /etc/rc (see rc(8)), and the
shutdown scripts invoked by /etc/rc.shutdown. The rc.conf file is a
shell script that is sourced by rc(8), meaning that rc.conf must contain
valid shell commands.
Listed below are the standard rc.conf 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.
By default, rc.conf reads /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 rc.conf.
rc.d(8) scripts that use load_rc_config from rc.subr(8) also support
sourcing an optional end-user provided per-script override file
/etc/rc.conf.d/service, (where service is the contents of the name
variable in the rc.d(8) script). This may contain variable overrides,
including allowing the end-user to override various run_rc_command
rc.d(8) control variables, and thus changing the operation of the script
without requiring editing of the script.
Variable naming conventions and data types
Most variables are one of two types: enabling variables or flags
variables. Enabling variables, such as inetd, are generally named after
the program or the system they enable, and have boolean values (specified
using `YES', `TRUE', `ON' or `1' for true, and `NO', `FALSE', `OFF' or
`0' for false, with the values being case insensitive). Flags variables,
such as inetd_flags have the same name with "_flags" appended, and
determine what arguments are passed to the program if it is enabled.
If a variable that rc(8) expects to be set is not set, or the value is
not one of the allowed values, a warning will be printed.
Overall control
do_rcshutdown Boolean value. If false, shutdown(8) will not run
/etc/rc.shutdown.
rcshutdown_rcorder_flags
A string. Extra arguments to the rcorder(8) run by
/etc/rc.shutdown.
rcshutdown_timeout
A number. If non-blank, use this as the number of
seconds to run a watchdog timer for which will terminate
/etc/rc.shutdown if the timer expires before the shutdown
script completes.
rc_configured Boolean value. If false then the system will drop into
single-user mode during boot.
rc_fast_and_loose
If set to a non-empty string, each script in /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 fork(2) operation.
Note: Use this at your own risk! A rogue command or
script may inadvertently prevent boot to
multiuser.
rc_rcorder_flags
A string. Extra arguments to the rcorder(8) run by
/etc/rc.
rc_directories A string. Space separated list of directories searched
for rc scripts. The default is /etc/rc.d. All
directories in rc_directories must be located in the root
file system, otherwise they will be silently skipped.
rc_silent Boolean value. If true then the usual output is
suppressed, and rc(8) invokes the command specified in
the rc_silent_cmd variable once for each line of
suppressed output. The default value of rc_silent is set
from the AB_SILENT flag in the kernel's boothowto
variable (see boot(8), reboot(2)).
rc_silent_cmd A command to be executed once per line of suppressed
output, when rc_silent is true. The default value of
rc_silent_cmd is `twiddle', which will display a spinning
symbol instead of each line of output. Another useful
value is `:', which will display nothing at all.
Basic network configuration
defaultroute A string. Default IPv4 network route. If empty or not
set, then the contents of /etc/mygate (if it exists) are
used.
defaultroute6 A string. Default IPv6 network route. If empty or not
set, then the contents of /etc/mygate6 (if it exists) are
used.
domainname A string. NIS (YP) domain of host. If empty or not set,
then the contents of /etc/defaultdomain (if it exists)
are used.
force_down_interfaces
A space separated list of interface names. These
interfaces will be configured down when going from
multiuser to single-user mode or on system shutdown.
dns_domain A string. Sets domain in /etc/resolv.conf.
dns_search A string. Sets search in /etc/resolv.conf.
dns_nameservers
A string of space separated domain name servers. Sets
nameserver for each value in /etc/resolv.conf.
dns_sortlist A string. Sets sortlist in /etc/resolv.conf.
dns_options A string. Sets options in /etc/resolv.conf.
dns_metric An unsigned integer. Sets the priority of the above DNS
to other sources, lowest wins. Defaults to 0.
This is important for some stateful interfaces, for
example PPPoE interfaces which have no direct means of
noticing "disconnect" events.
All active pppoe(4) interfaces will be automatically
added to this list.
hostname A string. Name of host. If empty or not set, then the
contents of /etc/myname (if it exists) are used.
Boottime file-system and swap configuration
critical_filesystems_local
A string. File systems mounted very early in the system
boot before networking services are available. Usually
/var is part of this, because it is needed by services
such as dhcpcd(8) which may be required to get the
network operational. The default is `OPTIONAL:/var',
where the `OPTIONAL:' prefix means that it's not an error
if the file system is not present in fstab(5).
critical_filesystems_remote
A string. File systems such as /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 `OPTIONAL:/usr', where the
`OPTIONAL:' prefix means that it is not an error if the
file system is not present in fstab(5).
critical_filesystems_zfs
A string. Mount non-legacy ZFS file systems right after
mounting local file systems listed in
critical_filesystems_local variable. An entry can be
prefixed with `OPTIONAL:' which means that it is not an
error if the file system is not present among available
ZFS datasets. The default is ''.
fsck_flags A string. A file system is checked with fsck(8) during
boot before mounting it. This option may be used to
override the default command-line options passed to the
fsck(8) program.
When set to -y, 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.
modules Boolean value. If true, loads the modules specified in
modules.conf(5).
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.
resize_root Boolean value. Set to true to have the system resize the
root file system to fill its partition. Will only
attempt to resize the root file system if it is of type
ffs and does not have logging enabled. Defaults to
false.
swapoff Boolean value. Remove block-type swap devices at
shutdown time. Useful if swapping onto RAIDframe
devices.
swapoff_umount "auto" or "manual". Before removing block-type swap
devices, it is wise to unmount tmpfs filesystems to avoid
having to swap their contents back into RAM. By default
("auto") all tmpfs filesystems that contain no device
nodes are unmounted. Set to "manual" to explicitly
specify which filesystems to unmount before removing
swap.
swapoff_umount_fs
A space-separated list of absolute paths to tmpfs mount
points. If swapoff_umount is set to "manual", these
tmpfs filesystems will be forcibly unmounted before
removing block-type swap devices.
var_shm_symlink
A path. If set, names a path that /var/shm will be
symlinked to.
The path needs to live on a tmpfs file system. A typical
value (assuming /tmp is mounted on tmpfs) would be
/tmp/.shm.
Block device subsystems
ccd Boolean value. Configures concatenated disk devices
according to ccd.conf(5).
cgd Boolean value. Configures cryptographic disk devices.
Requires /etc/cgd/cgd.conf. See cgdconfig(8) for
additional details.
lvm Boolean value. Configures the logical volume manager.
See lvm(8) for additional details.
raidframe Boolean value. Configures raid(4), RAIDframe disk
devices. See raidctl(8) for additional details.
zfs Boolean value. Configures ZFS storage pools and ZFS file
systems.
One-time actions to perform or programs to run on boot-up
accounting Boolean value. Enables process accounting with
accton(8). Requires /var/account/acct to exist.
clear_tmp Boolean value. Clear /tmp after reboot.
dmesg Boolean value. Create /var/run/dmesg.boot from the
output of dmesg(8). Passes dmesg_flags.
entropy A string, either `check', `wait', or `' (empty). If set
and nonempty, then during boot-up, after random_seed and
rndctl, check for or wait until enough entropy before any
networking is enabled.
If not enough entropy is available, then:
⊕ With `entropy=check', stop multiuser boot and enter
single-user mode instead.
⊕ With `entropy=wait', wait until enough entropy is
available.
Note that `entropy=wait' may cause the system to hang
indefinitely at boot if it has neither a random seed nor
any hardware random number generators -- use with care.
If empty or not set, the system may come to multiuser
without entropy, which is unsafe to use on the internet;
it is the operator's responsibility to heed warnings from
the kernel and the daily security.conf(5) report to
remedy the problem -- see entropy(7).
envsys Boolean value. Sets preferences for the environmental
systems framework, envsys(4). Requires /etc/envsys.conf,
which is described in envsys.conf(5).
gpio Boolean value. Configure gpio(4) devices. See
gpio.conf(5).
ldconfig Boolean value. Configures a.out(5) runtime link editor
directory cache.
mixerctl Boolean value. Read mixerctl.conf(5) for how to set
mixer values. List in mixerctl_mixers the devices whose
settings are to be saved at shutdown and restored at
start-up.
newsyslog Boolean value. Run newsyslog to trim log files before
syslogd starts. Intended for laptop users. Passes
newsyslog_flags.
per_user_tmp Boolean value. Enables a per-user /tmp directory.
per_user_tmp_dir can be used to override the default
location of the "real" temporary directories,
/private/tmp. See security(7) for additional details.
quota Boolean value. Checks and enables quotas by running
quotacheck(8) and quotaon(8).
random_seed Boolean value. During boot-up, runs the rndctl(8)
utility with the -L flag to seed the random number
subsystem from an entropy file. During shutdown, runs
the rndctl(8) utility with the -S flag to save some
random information to the entropy file. The entropy file
name is specified by the random_file variable, and
defaults to /var/db/entropy-file. The entropy file must
be on a local file system that is writable early during
boot-up (just after the file systems specified in
critical_filesystems_local have been mounted), and
correspondingly late during shutdown.
rndctl Boolean value. Runs the rndctl(8) utility one or more
times according to the specification in rndctl_flags.
If rndctl_flags does not contain a semicolon (`;') then
it is expected to contain zero or more flags, followed by
one or more device or type names. The rndctl(8) command
will be executed once for each device or type name. If
the specified flags do not include any of -c, -C, -e, or
-E, then the flags -c and -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 -d or -t, then the flag -d is added, to
specify that the non-flag arguments are device names, not
type names.
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 rndctl_flags="wd0 wd1; -t tty;
-c -t net", the following commands will be executed:
rndctl -c -e -d wd0; rndctl -c -e -d wd1; rndctl -c -e -t
tty; rndctl -c -t net.
rtclocaltime Boolean value. Sets the real time clock to local time by
adjusting the sysctl(7) value of kern.rtc_offset. The
offset from UTC is calculated automatically according to
the time zone information in the file /etc/localtime.
savecore Boolean value. Runs the savecore(8) utility. Passes
savecore_flags. The directory where crash dumps are
stored is specified by savecore_dir. The default setting
is /var/crash.
sysdb Boolean value. Builds various system databases,
including /var/run/dev.cdb, /etc/spwd.db,
/var/db/netgroup.db, /var/db/services.cdb, and entries
for utmp(5).
tpctl Boolean value. Run tpctl(8) to calibrate touch panel
device. Passes tpctl_flags.
update_motd Boolean value. Updates the NetBSD version string in the
/etc/motd file to reflect the version of the running
kernel. See motd(5).
update_motd_release
Boolean value. If enabled in addition to update_motd,
updates a second NetBSD version string in the /etc/motd
file to reflect the version, architecture, and Build ID
of the installed userland. An optional prefix can be
provided for this version string in motd_release_tag.
virecover Boolean value. Send notification mail to users if any
recoverable files exist in /var/tmp/vi.recover. Read
virecover(8) for more information.
wdogctl Boolean value. Configures watchdog timers. Passes
wdogctl_flags. Refer to wdogctl(8) for information on
how to configure a timer.
System security settings
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 init(8) and secmodel_securelevel(9),
which contains definitive information about the system
securelevel. Note that setting securelevel to 0 in
rc.conf will actually result in the system booting with
securelevel set to 1, as init(8) will raise the level
when rc(8) completes.
permit_nonalpha
Boolean value. Allow passwords to include non-alpha
characters, usually to allow NIS/YP netgroups.
veriexec Boolean value. Load Veriexec fingerprints during
startup. Read veriexecctl(8) for more information.
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.
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.
veriexec_flags A string. Flags to pass to the veriexecctl command.
smtoff Boolean value. Disables SMT (Simultaneous Multi-
Threading).
Networking startup
altqd Boolean value. ALTQ configuration/monitoring daemon.
Passes altqd_flags.
auto_ifconfig Boolean value. Sets the net_interfaces variable (see
below) to the output of ifconfig(8) with the -l flag and
suppresses warnings about interfaces in this list that do
not have an ifconfig file or variable.
blocklistd Boolean value. Runs blocklistd(8) to dynamically block
hosts on a DoS according to configuration set in
blocklistd.conf(5) Passes blocklistd_flags.
dhcpcd Boolean value. Set true to configure some or all network
interfaces using dhcpcd. If you set dhcpcd true, then
/var must be in critical_filesystems_local, or /var must
be on the root file system. If you need to restrict
dhcpcd to one or a number of interfaces, or need a
separate configuration per interface, then this should be
done in the configuration file - see dhcpcd.conf(5) for
details. dhcpcd presently ignores the wpa_supplicant
variable in rc.conf and will start wpa_supplicant if a
suitable wpa_supplicant.conf is found unless otherwise
instructed in dhcpcd.conf(5).
dhcpcd_flags Passes dhcpcd_flags to dhcpcd. See dhcpcd(8) for
complete documentation.
flushroutes Boolean value. Flushes the route table on networking
startup. Useful when coming up to multiuser mode after
going down to single-user mode.
ftp_proxy Boolean value. Runs ftp-proxy(8), the proxy daemon for
the Internet File Transfer Protocol.
hostapd Boolean value. Runs hostapd(8), the authenticator for
IEEE 802.11 networks.
ifaliases_* A string. List of `address netmask' pairs to configure
additional network addresses for the given configured
interface (e.g. ifaliases_le0). If netmask is `-', then
use the default netmask for the interface.
ifaliases_* covers limited cases only and is considered
unrecommended. We recommend using ifconfig_xxN variables
or /etc/ifconfig.xxN files with multiple lines instead.
ifwatchd Boolean value. Monitor dynamic interfaces and perform
actions upon address changes. Passes ifwatchd_flags.
ip6addrctl Boolean value. Fine grain control of address and routing
priorities.
ip6addrctl_policy
A string. Can be:
`auto' automatically determine from system settings;
will read priorities from /etc/ip6addrctl.conf
or if that file does not exist it will default
to IPv6 first, then IPv4.
`ipv4_prefer'
try IPv4 before IPv6.
`ipv6_prefer'
try IPv6 before IPv4.
ip6addrctl_verbose
Boolean value. If set, print the resulting prefixes and
priorities map.
ip6mode A string. An IPv6 node can be a router (nodes that
forward packet for others) or a host (nodes that do not
forward). A host can be autoconfigured based on the
information advertised by adjacent IPv6 routers. By
setting ip6mode to `router', `host', or `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.
ip6uniquelocal Boolean value. If ip6mode is equal to `router', and
ip6uniquelocal is false, a reject route will be installed
on boot to avoid misconfiguration relating to unique-
local addresses. If ip6uniquelocal is true, the reject
route won't be installed.
ipfilter Boolean value. Runs ipf(8) to load in packet filter
specifications from /etc/ipf.conf at network boot time,
before any interfaces are configured. Passes
ipfilter_flags. See ipf.conf(5).
ipfs Boolean value. Runs ipfs(8) to save and restore
information for ipnat and ipfilter state tables. The
information is stored in /var/db/ipf/ipstate.ipf and
/var/db/ipf/ipnat.ipf. Passes ipfs_flags.
ipmon Boolean value. Runs ipmon(8) to read ipf(8) packet log
information and log it to a file or the system log.
Passes ipmon_flags.
ipmon_flags A string. Specifies arguments to supply to ipmon(8).
Defaults to `-ns'. A typical example would be `-nD
/var/log/ipflog' to have ipmon(8) log directly to a file
bypassing syslogd(8). If the -D argument is used,
remember to modify /etc/newsyslog.conf accordingly; for
example:
/var/log/ipflog 640 10 100 * Z /var/run/ipmon.pid
ipnat Boolean value. Runs ipnat(8) to load in the IP network
address translation (NAT) rules from /etc/ipnat.conf at
network boot time, before any interfaces are configured.
See ipnat.conf(5).
ipsec Boolean value. Runs setkey(8) to load in IPsec manual
keys and policies from /etc/ipsec.conf at network boot
time, before any interfaces are configured.
npf Boolean value. Loads npf.conf(5) at network boot time,
and starts npf(7).
npfd Boolean value. Runs npfd(8), the NPF packet filter
logging and state synchronization daemon. Passes
npfd_flags.
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 ifconfig_xxN, and then in the file
/etc/ifconfig.xxN. If 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 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.
One common case it to set the ifconfig_xxN variable to a
set of arguments to be passed to an ifconfig(8) command
after the interface name. Refer to ifconfig.if(5) for
more details on /etc/ifconfig.xxN files, and note that
the information there also applies to ifconfig_xxN
variables (after the variables are split into lines).
ntpdate Boolean value. Runs ntpdate(8) to set the system time
from one of the hosts in ntpdate_hosts. If ntpdate_hosts
is empty, it will attempt to find a list of hosts in
/etc/ntp.conf. Passes ntpdate_flags.
pf Boolean value. Enable pf(4) at network boot time: Load
the initial configuration pf.boot.conf(5) before the
network is up. After the network has been configured,
then load the final rule set pf.conf(5).
pf_rules A string. The path of the pf.conf(5) rule set that will
be used when loading the final rule set.
pflogd Boolean value. Run pflogd(8) for dumping packet filter
logging information to a file.
ppp A boolean. Toggles starting pppd(8) on startup. See
ppp_peers below.
ppp_peers A string. If ppp is true and ppp_peers is not empty,
then /etc/rc.d/ppp will check each word in ppp_peers for
a corresponding ppp configuration file in /etc/ppp/peers
and will call pppd(8) with the "call peer" option.
racoon Boolean value. Runs racoon(8), the IKE (ISAKMP/Oakley)
key management daemon.
wpa_supplicant Boolean value. Run wpa_supplicant(8), WPA/802.11i
Supplicant for wireless network devices. If you set
wpa_supplicant true, then /usr must be in
critical_filesystems_local, or /usr must be on the root
file system. dhcpcd ignores this variable, see the
dhcpcd variable for details.
Daemons required by other daemons
inetd Boolean value. Runs the inetd(8) daemon to start network
server processes (as listed in /etc/inetd.conf) as
necessary. Passes inetd_flags. The -l flag turns on
libwrap connection logging.
rpcbind Boolean value. The rpcbind(8) daemon is required for any
rpc(3) services. These include NFS, NIS,
rpc.bootparamd(8), rpc.rstatd(8), rpc.rusersd(8), and

initialization. It is preferred to httpd_user because
httpd(8) is requiring extra privileges to start listening
on default port 80. The default setting is `_httpd'.
lpd Boolean value. Runs lpd(8) and passes lpd_flags. The -l
flag will turn on extra logging.
mdnsd Boolean value. Runs mdnsd(8).
named Boolean value. Runs named(8) and passes named_flags.
named_chrootdir
A string. If non-blank and named is true, run named(8)
as the unprivileged user and group `named', chroot(2)ed
to named_chrootdir. ${named_chrootdir}/var/run/log will
be added to the list of log sockets that syslogd(8)
listens to.
ntpd Boolean value. Runs ntpd(8) and passes ntpd_flags.
ntpd_chrootdir A string. If non-blank and ntpd is true, run ntpd(8) as
the unprivileged user and group `ntpd', chroot(2)ed to
ntpd_chrootdir. ${ntpd_chrootdir}/var/run/log will be
added to the list of log sockets that syslogd(8) listens
to. This option requires that the kernel has
pseudo-device clockctl
compiled in, and that /dev/clockctl is present.
postfix Boolean value. Starts postfix(1) mail system.
sshd Boolean value. Runs sshd(8) and passes sshd_flags.
syslogd Boolean value. Runs syslogd(8) and passes syslogd_flags.
timed Boolean value. Runs timed(8) and passes timed_flags.
The -M option allows timed(8) to be a master time source
as well as a slave. If you are also running ntpd(8),
only one machine running both should have the -M flag
given to timed(8).

rtadvd Boolean value. Runs rtadvd(8), the IPv6 router
advertisement daemon, which is used to advertise
information about the subnet to IPv6 end hosts. Passes
rtadvd_flags. This is only for IPv6 routers, so set
ip6mode to `router' if you use it.
X Window System daemons
xdm Boolean value. Runs the xdm(1) X display manager. These
X daemons are available only with the optional X
distribution of NetBSD.
xfs Boolean value. Runs the xfs(1) X11 font server, which
supplies local X font files to X terminals.
NIS (YP) daemons
ypbind Boolean value. Runs ypbind(8), which lets NIS (YP)
clients use information from a NIS server. Passes
ypbind_flags.
yppasswdd Boolean value. Runs yppasswdd(8), which allows remote
NIS users to update password on master server. Passes
yppasswdd_flags.
ypserv Boolean value. Runs ypserv(8), the NIS (YP) server for
distributing information from certain files in /etc.
Passes ypserv_flags. The -d flag causes it to use DNS
for lookups in /etc/hosts that fail.
