.Dt RC.CONF 5
.Os
.Sh NAME
.Nm rc.conf
.Nd system configuration information
.Sh DESCRIPTION
The file
.Nm
contains descriptive information about the local host name, configuration
details for any potential network interfaces and which services should be
started up at system initial boot time.
In new installations, the
.Nm
file is generally initialized by the system installation utility,
.Xr sysinstall 8 .
.Pp
The purpose of
.Nm
is not to run commands or perform system startup actions
directly.
Instead, it is included by the
various generic startup scripts in
.Pa /etc
which conditionalize their
internal actions according to the settings found there.
.Pp
The
.Pa /etc/rc.conf
file is included from the file
.Pa /etc/defaults/rc.conf ,
which specifies the default settings for all the available options.
Options need only be specified in
.Pa /etc/rc.conf
when the system administrator wishes to override these defaults.
The file
.Pa /etc/rc.conf.local
is used to override settings in
.Pa /etc/rc.conf
for historical reasons.
See the
.Va rc_conf_files
variable below.
.Pp
Options are set with
.Dq Ar name Ns Li = Ns Ar value
assignments that use
.Xr sh 1
syntax.
The following list provides a name and short description for each
variable that can be set in the
.Nm
file:
.Bl -tag -width indent-two
.It Va rc_debug
.Pq Vt bool
If set to
.Dq Li YES ,
enable output of debug messages from rc scripts.
This variable can be helpful in diagnosing mistakes when
editing or integrating new scripts.
Beware that this produces copious output to the terminal and
.Xr syslog 3 .
.It Va rc_info
.Pq Vt bool
If set to
.Dq Li NO ,
disable informational messages from the rc scripts.
Informational messages are displayed when
a condition that is not serious enough to warrant a warning or
an error occurs.
.It Va early_late_divider
.Pq Vt str
The name of the script that should be used as the
delimiter between the
.Dq early
and
.Dq late
stages of the boot process.
The early stage should contain all the services needed to
get the disks (local or remote) mounted so that the late
stage can include scripts contained in the directories
listed in the
.Va local_startup
variable (see below).
Thus, the two likely candidates for this value are
.Pa mountcritlocal
for the typical system, and
.Pa mountcritremote
if the system needs remote file
systems mounted to get access to the
.Va local_startup
directories; for example when
.Pa /usr/local
is NFS mounted.
For
.Pa rc.conf
within a
.Xr jail 8
.Pa NETWORKING
is likely to be an appropriate value.
Extreme care should be taken when changing this value,
and before changing it one should ensure that there are
adequate provisions to recover from a failed boot
(such as physical contact with the machine,
or reliable remote console access).
.It Va swapfile
.Pq Vt str
If set to
.Dq Li NO ,
no swapfile is installed, otherwise the value is used as the full
pathname to a file to use for additional swap space.
.It Va apm_enable
.Pq Vt bool
If set to
.Dq Li YES ,
enable support for Automatic Power Management with
the
.Xr apm 8
command.
.It Va apmd_enable
.Pq Vt bool
Run
.Xr apmd 8
to handle APM event from userland.
This also enables support for APM.
.It Va apmd_flags
.Pq Vt str
If
.Va apmd_enable
is set to
.Dq Li YES ,
these are the flags to pass to the
.Xr apmd 8
daemon.
.It Va devd_enable
.Pq Vt bool
Run
.Xr devd 8
to handle device added, removed or unknown events from the kernel.
.It Va kldxref_enable
.Pq Vt bool
Set to
.Dq Li NO
by default.
Set to
.Dq Li YES
to automatically rebuild
.Pa linker.hints
files with
.Xr kldxref 8
at boot time.
.It Va kldxref_clobber
.Pq Vt bool
Set to
.Dq Li NO
by default.
If
.Va kldxref_enable
is true,
setting to
.Dq Li YES
will overwrite existing
.Pa linker.hints
files at boot time.
Otherwise,
only missing
.Pa linker.hints
files are generated.
.It Va kldxref_module_path
.Pq Vt str
Empty by default.
A semi-colon
.Pq Ql \&;
delimited list of paths containing
.Xr kld 4
modules.
If empty,
the contents of the
.Va kern.module_path
.Xr sysctl 8
are used.
.It Va powerd_enable
.Pq Vt bool
If set to
.Dq Li YES ,
enable the system power control facility with the
.Xr powerd 8
daemon.
.It Va powerd_flags
.Pq Vt str
If
.Va powerd_enable
is set to
.Dq Li YES ,
these are the flags to pass to the
.Xr powerd 8
daemon.
.It Va tmpmfs
Controls the creation of a
.Pa /tmp
memory file system.
Always happens if set to
.Dq Li YES
and never happens if set to
.Dq Li NO .
If set to anything else, a memory file system is created if
.Pa /tmp
is not writable.
.It Va tmpsize
Controls the size of a created
.Pa /tmp
memory file system.
.It Va tmpmfs_flags
Extra options passed to the
.Xr mdmfs 8
utility when the memory file system for
.Pa /tmp
is created.
The default is
.Dq Li "-S" ,
which inhibits the use of softupdates on
.Pa /tmp
so that file system space is freed without delay
after file truncation or deletion.
See
.Xr mdmfs 8
for other options you can use in
.Va tmpmfs_flags .
.It Va varmfs
Controls the creation of a
.Pa /var
memory file system.
Always happens if set to
.Dq Li YES
and never happens if set to
.Dq Li NO .
If set to anything else, a memory file system is created if
.Pa /var
is not writable.
.It Va varsize
Controls the size of a created
.Pa /var
memory file system.
.It Va varmfs_flags
Extra options passed to the
.Xr mdmfs 8
utility when the memory file system for
.Pa /var
is created.
The default is
.Dq Li "-S" ,
which inhibits the use of softupdates on
.Pa /var
so that file system space is freed without delay
after file truncation or deletion.
See
.Xr mdmfs 8
for other options you can use in
.Va varmfs_flags .
.It Va populate_var
Controls the automatic population of the
.Pa /var
file system.
Always happens if set to
.Dq Li YES
and never happens if set to
.Dq Li NO .
If set to anything else, a memory file system is created if
.Pa /var
is not writable.
Note that this process requires access to certain commands in
.Pa /usr
before
.Pa /usr
is mounted on normal systems.
.It Va cleanvar_enable
.Pq Vt bool
Clean the
.Pa /var
directory.
.It Va local_startup
.Pq Vt str
List of directories to search for startup script files.
.It Va script_name_sep
.Pq Vt str
The field separator to use for breaking down the list of startup script files
into individual filenames.
The default is a space.
It is not necessary to change this unless there are startup scripts with names
containing spaces.
.It Va hostapd_enable
.Pq Vt bool
Set to
.Dq Li YES
to start
.Xr hostapd 8
at system boot time.
.It Va hostname
.Pq Vt str
The fully qualified domain name (FQDN) of this host on the network.
This should almost certainly be set to something meaningful, even if
there is no network connection.
If
.Xr dhclient 8
is used to set the hostname via DHCP,
this variable should be set to an empty string.
.It Va ipv6_enable
.Pq Vt bool
Enable support for IPv6 networking.
Note that this requires that the kernel has been compiled with
.Cd "options INET6" .
.It Va nisdomainname
.Pq Vt str
The NIS domain name of this host, or
.Dq Li NO
if NIS is not used.
.It Va dhclient_program
.Pq Vt str
Path to the DHCP client program
.Pa ( /sbin/dhclient ,
the
.Ox
DHCP client,
is the default).
.It Va dhclient_flags
.Pq Vt str
Additional flags to pass to the DHCP client program.
For the
.Ox
DHCP client, see the
.Xr dhclient 8
manpage for a description of the command line options available.
.It Va dhclient_flags_ Ns Aq Ar iface
Additional flags to pass to the DHCP client program running on
.Ar iface
only.
When specified, this variable overrides
.Va dhclient_flags .
.It Va background_dhclient
.Pq Vt bool
Set to
.Dq Li YES
to start the DHCP client in background.
This can cause trouble with applications depending on
a working network, but it will provide a faster startup
in many cases.
.It Va background_dhclient_ Ns Aq Ar iface
When specified, this variable overrides the
.Va background_dhclient
variable for interface
.Ar iface
only.
.It Va synchronous_dhclient
.Pq Bt bool
Set to
.Dq Li NO
to start
.Xr dhclient 8
only in response to interface events and not synchronously at startup.
This behavior can be overridden on a per-interface basis by replacing
the
.Dq Li DHCP
keyword in the
.Va ifconfig_ Ns Aq Ar interface
variable with
.Dq Li SYNCDHCP
or
.Dq Li NOSYNCDHCP .
.It Va firewall_enable
.Pq Vt bool
Set to
.Dq Li YES
to load firewall rules at startup.
If the kernel was not built with
.Cd "options IPFIREWALL" ,
the
.Pa ipfw.ko
kernel module will be loaded.
See also
.Va ipfilter_enable .
.It Va ipv6_firewall_enable
.Pq Vt bool
The IPv6 equivalent of
.Va firewall_enable .
Set to

kernel module will be loaded.
.It Va firewall_script
.Pq Vt str
This variable specifies the full path to the firewall script to run.
The default is
.Pa /etc/rc.firewall .
.It Va ipv6_firewall_script
.Pq Vt str
The IPv6 equivalent of
.Va firewall_script .
.It Va firewall_type
.Pq Vt str
Names the firewall type from the selection in
.Pa /etc/rc.firewall ,
or the file which contains the local firewall ruleset.
Valid selections from
.Pa /etc/rc.firewall
are:
.Pp
.Bl -tag -width ".Li simple" -compact
.It Li open
unrestricted IP access
.It Li closed
all IP services disabled, except via
.Dq Li lo0
.It Li client
basic protection for a workstation
.It Li simple
basic protection for a LAN.
.El
.Pp
If a filename is specified, the full path
must be given.
.It Va ipv6_firewall_type
.Pq Vt str
The IPv6 equivalent of
.Va firewall_type .
.It Va firewall_quiet
.Pq Vt bool
Set to
.Dq Li YES
to disable the display of firewall rules on the console during boot.
.It Va ipv6_firewall_quiet
.Pq Vt bool
The IPv6 equivalent of
.Va firewall_quiet .
.It Va firewall_logging
.Pq Vt bool
Set to

.Pq Vt str
Path to
.Xr natd 8 .
.It Va natd_enable
.Pq Vt bool
Set to
.Dq Li YES
to enable
.Xr natd 8 .
.Va firewall_enable
must also be set to
.Dq Li YES ,
and
.Xr divert 4
sockets must be enabled in the kernel.
If the kernel was not built with
.Cd "options IPDIVERT" ,
the
.Pa ipdivert.ko
kernel module will be loaded.
.It Va natd_interface
.Pq Vt str
This is the name of the public interface on which
.Xr natd 8
should run.
The interface may be given as an interface name or as an IP address.
.It Va natd_flags
.Pq Vt str
Additional
.Xr natd 8
flags should be placed here.
The
.Fl n
or
.Fl a
flag is automatically added with the above
.Va natd_interface
as an argument.
.\" ----- ipfilter_enable setting --------------------------------
.It Va ipfilter_enable
.Pq Vt bool
Set to
.Dq Li NO
by default.
Setting this to
.Dq Li YES
enables
.Xr ipf 8
packet filtering.
.Pp
Typical usage will require putting
.Bd -literal
ipfilter_enable="YES"
ipnat_enable="YES"
ipmon_enable="YES"
ipfs_enable="YES"
.Ed
.Pp
into
.Pa /etc/rc.conf
and editing
.Pa /etc/ipf.rules
and
.Pa /etc/ipnat.rules
appropriately.
.Pp
Note that
.Va ipfilter_enable
and
.Va ipnat_enable
can be enabled independently.
.Va ipmon_enable
and
.Va ipfs_enable
both require at least one of
.Va ipfilter_enable
and
.Va ipnat_enable
to be enabled.
.Pp
Having
.Bd -literal
options IPFILTER
options IPFILTER_LOG
options IPFILTER_DEFAULT_BLOCK
.Ed
.Pp
in the kernel configuration file is a good idea, too.

.\" ----- end of added ipf hook ---------------------------------
.It Va pf_enable
.Pq Vt bool
Set to
.Dq Li NO
by default.
Setting this to
.Dq Li YES
enables
.Xr pf 4
packet filtering.
.Pp
Typical usage will require putting
.Pp
.Dl pf_enable="YES"
.Pp
into
.Pa /etc/rc.conf
and editing
.Pa /etc/pf.conf
appropriately.
.Pp
.Dl "device pf"
.Pp
builds
.Xr pf 4

packet filter.
.It Va pflog_logfile
.Pq Vt str
If
.Va pflog_enable
is set to
.Dq Li YES
this controls where
.Xr pflogd 8
stores the logfile
(default
.Pa /var/log/pflog ) .
Check
.Pa /etc/newsyslog.conf
to adjust logfile rotation for this.
.It Va pflog_program
.Pq Vt str
Path to
.Xr pflogd 8
(default
.Pa /sbin/pflogd ) .
.It Va pflog_flags
.Pq Vt str
Empty by default.
This variable contains additional flags passed to the
.Xr pflogd 8
program.

Setting this to
.Dq Li YES
enables exposing
.Xr pf 4
state changes to other hosts over the network by means of
.Xr pfsync 4 .
The
.Va pfsync_syncdev
variable
must also be set then.
.It Va pfsync_syncdev
.Pq Vt str
Empty by default.
This variable specifies the name of the network interface
.Xr pfsync 4
should operate through.
It must be set accordingly if
.Va pfsync_enable
is set to
.Dq Li YES .
.It Va pfsync_ifconfig
.Pq Vt str
Empty by default.
This variable can contain additional options to be passed to the

command used to set up
.Xr pfsync 4 .
.It Va tcp_extensions
.Pq Vt bool
Set to
.Dq Li YES
by default.
Setting this to
.Dq Li NO
disables certain TCP options as described by
.Rs
.%T "RFC 1323"
.Re
Setting this to
.Dq Li NO
might help remedy such problems with connections as randomly hanging
or other weird behavior.
Some network devices are known
to be broken with respect to these options.
.It Va log_in_vain
.Pq Vt int
Set to 0 by default.
The
.Xr sysctl 8
variables,
.Va net.inet.tcp.log_in_vain
and
.Va net.inet.udp.log_in_vain ,
as described in
.Xr tcp 4
and
.Xr udp 4 ,
are set to the given value.
.It Va tcp_keepalive
.Pq Vt bool
Set to
.Dq Li YES
by default.
Setting to
.Dq Li NO
will disable probing idle TCP connections to verify that the
peer is still up and reachable.
.It Va tcp_drop_synfin
.Pq Vt bool
Set to
.Dq Li NO
by default.
Setting to
.Dq Li YES
will cause the kernel to ignore TCP frames that have both
the SYN and FIN flags set.
This prevents OS fingerprinting, but may
break some legitimate applications.
This option is only available if the
kernel was built with the
.Dv TCP_DROP_SYNFIN
option.
.It Va icmp_drop_redirect
.Pq Vt bool
Set to
.Dq Li NO
by default.
Setting to
.Dq Li YES
will cause the kernel to ignore ICMP REDIRECT packets.
Refer to
.Xr icmp 4
for more information.
.It Va icmp_log_redirect
.Pq Vt bool
Set to
.Dq Li NO
by default.
Setting to
.Dq Li YES
will cause the kernel to log ICMP REDIRECT packets.
Note that
the log messages are not rate-limited, so this option should only be used
for troubleshooting networks.
Refer to
.Xr icmp 4
for more information.
.It Va icmp_bmcastecho
.Pq Vt bool
Set to
.Dq Li YES
to respond to broadcast or multicast ICMP ping packets.
Refer to
.Xr icmp 4
for more information.
.It Va ip_portrange_first
.Pq Vt int
If not set to
.Dq Li NO ,
this is the first port in the default portrange.
Refer to
.Xr ip 4
for more information.
.It Va ip_portrange_last
.Pq Vt int
If not set to
.Dq Li NO ,
this is the last port in the default portrange.
Refer to
.Xr ip 4
for more information.
.It Va network_interfaces
.Pq Vt str
Set to the list of network interfaces to configure on this host or
.Dq Li AUTO
(the default) for all current interfaces.
Setting the
.Va network_interfaces
variable to anything other than the default is deprecated.
Interfaces that the administrator wishes to store configuration for,
but not start at boot should be configured with the
.Dq Li NOAUTO
keyword in their
.Va ifconfig_ Ns Aq Ar interface
variables as described below.
.Pp
An
.Va ifconfig_ Ns Aq Ar interface
variable is also assumed to exist for each value of
.Ar interface .
When an interface name contains any of the characters
.Dq Li .-/+
they are translated to
.Dq Li _
before lookup.
The variable can contain arguments to
.Xr ifconfig 8 ,
as well as special case-insensitive keywords described below.
Such keywords are removed before passing the value to
.Xr ifconfig 8
while the order of the other arguments is preserved.
.Pp
One can configure more than one IPv4 address with the
.Va ipv4_addrs_ Ns Aq Ar interface
variable.
One or more IP addresses must be provided in Classless Inter-Domain
Routing (CIDR) address notation, whose last byte can be a range like
192.168.0.5-23/24.
In this case the address 192.168.0.5 will be configured with the
netmask /24 and the addresses 192.168.0.6 to 192.168.0.23 with
the non-conflicting netmask /32 as explained in the
.Xr ifconfig 8
alias section.
With the interface in question being
.Li ed0 ,
an example could look like:
.Bd -literal
ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"
.Ed
.Pp
It is also possible to add IP alias entries using
.Xr ifconfig 8
syntax.
Assuming that the interface in question was
.Li ed0 ,
it might look
something like this:
.Bd -literal
ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"
.Ed
.Pp
And so on.
For each
.Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
entry that is found,
its contents are passed to
.Xr ifconfig 8 .
Execution stops at the first unsuccessful access, so if
something like this is present:
.Bd -literal
ifconfig_ed0_alias0="inet 127.0.0.251 netmask 0xffffffff"
ifconfig_ed0_alias1="inet 127.0.0.252 netmask 0xffffffff"
ifconfig_ed0_alias2="inet 127.0.0.253 netmask 0xffffffff"
ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
.Ed
.Pp
Then note that alias4 would
.Em not
be added since the search would
stop with the missing
.Dq Li alias3
entry.
Due to this difficult to manage behavior, the
.Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
form is deprecated.
.Pp
If the
.Pa /etc/start_if. Ns Aq Ar interface
file is present, it is read and executed by the
.Xr sh 1
interpreter
before configuring the interface as specified in the
.Va ifconfig_ Ns Aq Ar interface
and
.Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
variables.
.Pp
If the
.Va ifconfig_ Ns Aq Ar interface
contains the keyword
.Dq Li NOAUTO
then the interface will not be configured
at boot or by
.Pa /etc/pccard_ether
when
.Va network_interfaces
is set to
.Dq Li AUTO .
.Pp
It is possible to bring up an interface with DHCP by adding
.Dq Li DHCP
to the
.Va ifconfig_ Ns Aq Ar interface
variable.
For instance, to initialize the
.Li ed0
device via DHCP,
it is possible to use something like:
.Bd -literal
ifconfig_ed0="DHCP"
.Ed
.Pp
Also, if your interface needs WPA authentication, it is possible to add
.Dq Li WPA
to the
.Va ifconfig_ Ns Aq Ar interface
variable.
.Pp
Finally, you can add
.Xr ifconfig 8
options in this variable, in addition to the
.Pa /etc/start_if. Ns Aq Ar interface
file.
For instance, to initialize the
.Li wi0
device via DHCP, using WPA authentication and 802.11b mode, it is
possible to use something like:
.Bd -literal
ifconfig_wi0="DHCP WPA mode 11b"
.Ed
.Pp
In addition to the
.Va ifconfig_ Ns Aq Ar interface
form, a fallback variable
.Va ifconfig_DEFAULT
may be configured.
It will be used for all interfaces with no
.Va ifconfig_ Ns Aq Ar interface
variable.
This is intended to replace the no longer supported
.Va pccard_ifconfig
variable.
.Pp
It is also possible to rename interface by doing:
.Bd -literal
ifconfig_ed0_name="net0"
ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"
.Ed
.It Va ipv6_network_interfaces
.Pq Vt str
This is the IPv6 equivalent of
.Va network_interfaces .
Instead of setting the ifconfig variables as
.Va ifconfig_ Ns Aq Ar interface
they should be set as
.Va ipv6_ifconfig_ Ns Aq Ar interface .
Aliases should be set as
.Va ipv6_ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n .
.Va ipv6_prefix_ Ns Aq Ar interface
does something.
Interfaces that do not have a
.Va ipv6_ifconfig_ Ns Aq Ar interface
setting will be auto configured by
.Xr rtsol 8
if the
.Va ipv6_gateway_enable
is set to
.Dq Li NO .
Note that the IPv6 networking code does not support the
.Pa /etc/start_if. Ns Aq Ar interface
files.
.It Va ipv6_default_interface

Set to the list of
.Xr ng_fec 4
Fast EtherChannel interfaces to configure on this host.
A
.Va fecconfig_ Ns Aq Ar interface
variable is assumed to exist for each value of
.Ar interface .
The value of this variable is used to configure link aggregated interfaces
according to the syntax of the
.Cm NGM_FEC_ADD_IFACE
to
.Xr ngctl 8
msg.
Additionally, this option ensures that each listed interface is created
via the
.Cm mkpeer
command to
.Xr ngctl 8
before attempting to configure it.
For example:
.Bd -literal
fec_interfaces="fec0"
fecconfig_fec0="em0 em1"
ifconfig_fec0="DHCP"
.Ed
.It Va gif_interfaces
.Pq Vt str
Set to the list of

variable is assumed to exist for each value of
.Ar interface .
The value of this variable is used to configure the link layer of the
tunnel according to the syntax of the
.Cm tunnel
option to
.Xr ifconfig 8 .
Additionally, this option ensures that each listed interface is created
via the
.Cm create
option to
.Xr ifconfig 8
before attempting to configure it.
.It Va sppp_interfaces
.Pq Vt str
Set to the list of
.Xr sppp 4
interfaces to configure on this host.
A
