.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 installer.
.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/defaults/rc.conf
file specifies the default settings for all the available options,
the
.Pa /etc/rc.conf
file specifies override settings.
Options need only be specified in
.Pa /etc/rc.conf
when the system administrator wishes to override the defaults.
The file
.Pa /etc/rc.conf.local
is used to override settings in
.Pa /etc/rc.conf
for historical reasons.
In addition to
.Pa /etc/rc.conf.local
you can also place smaller configuration files for each
.Xr rc 8
script in the
.Pa /etc/rc.conf.d
directory, which will be included by the
.Va load_rc_config
function.
For jail configurations you could use the file
.Pa /etc/rc.conf.d/jail
to store jail specific configuration options.
Also see the
.Va rc_conf_files
variable below.
.Pp
The following list provides a name and short description for each
variable that can be set in the
.Nm
file.
To set a variable of
.Vt bool
type, specify either
.Dq Li YES ,
.Dq Li TRUE ,
.Dq Li ON ,
or
.Dq Li 1 .
To unset, specify
.Dq Li NO ,
.Dq Li FALSE ,
.Dq Li OFF ,
or
.Dq Li 0 .
These values are case insensitive.
The

.\"
.It Va ifconfig_ Ns Aq Ar interface
.Pq Vt str
Configuration for
.Dq interface .
Typically includes IP address.
Assuming that the interface in question was
.Li ed0 ,
it might look something like this:
.Bd -literal
ifconfig_ed0="inet 10.0.0.1 netmask 0xffff0000"
.Ed
.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
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
If a
.Va vlans_ Ns Aq Ar interface
variable is set,
a
.Xr vlan 4
interface will be created for each item in the list with the
.Ar vlandev
argument set to
.Ar interface .
If a vlan interface's name is a number,
then that number is used as the vlan tag and the new vlan interface is
named
.Ar interface . Ns Ar tag .
Otherwise,
the vlan tag must be specified via a
.Va vlan
parameter in the
.Va create_args_ Ns Aq Ar interface
variable.
.Pp
To create a vlan device named
.Li em0.101
on
.Li em0
with the vlan tag 101 and the optional the IPv4 address 192.0.2.1/24:
.Bd -literal
vlans_em0="101"
ifconfig_em0_101="inet 192.0.2.1/24"
.Ed
.Pp
To create a vlan device named
.Li myvlan
on
.Li em0
with the vlan tag 102:
.Bd -literal
vlans_em0="myvlan"
create_args_myvlan="vlan 102"
.Ed
.Pp
If a
.Va wlans_ Ns Aq Ar interface
variable is set,
an
.Xr wlan 4
interface will be created for each item in the list with the
.Ar wlandev
argument set to
.Ar interface .
Further wlan cloning arguments may be passed to the
.Xr ifconfig 8
.Cm create
command by setting the
.Va create_args_ Ns Aq Ar interface
variable.
One or more
.Xr wlan 4
devices must be created for each wireless devices as of
.Dx 2.5 .
Debugging flags for
.Xr wlan 4
devices as set by
.Xr wlandebug 8
may be specified with an
.Va wlandebug_ Ns Aq Ar interface
variable.
The contents of this variable will be passed directly to
.Xr wlandebug 8 .
.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.
This will start
.Xr wpa_supplicant 8 .
See
.Xr wpa_supplicant.conf 5
for configuring authentication information.
.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
wlans_wi0="wlan0"
ifconfig_wlan0="up DHCP WPA mode 11b"
.Ed
.It Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
.Pq Vt str
Configuration to establish an additional network address for
.Dq interface .
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 alias3 entry.
.It Va ifconfig_ Ns Ao Ar interface Ac Ns Va _name
.Pq Vt str
New name for
.Dq interface .
It is possible to rename interface by doing:
.Bd -literal
ifconfig_ed0_name="net0"
ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"
.Ed
.It Va netif_enable
.Pq Vt bool
Set to
.Dq Li YES
by default.
Setting to
.Dq Li NO
will disable the configuration of network interfaces.
.It Va network_interfaces
.Pq Vt str
The list of network interfaces to configure on this host,
or
.Dq Li auto
to configure all network interfaces
(default
.Dq Li auto ) .
For example, if the only network devices to be configured are the loopback device
.Pq Li lo0
and a NIC using the
.Xr em 4
driver, this could be set to
.Dq Li "lo0 em0" .
An
.Va ifconfig_ Ns Aq Ar interface
variable is assumed to exist for each value of
.Ar interface .
.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 .
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_prefix_ Ns Aq Ar interface
.Pq Vt str
Assign prefix to
.Ar interface ,
prefixlen 64 is used.
.It Va ipv6_default_interface
.Pq Vt str
If not set to
.Dq Li NO ,
this is the default output interface for scoped addresses.
Now this works only for IPv6 link local multicast addresses.
.It Va ip6addrctl_enable
.Pq Vt bool
This variable is to enable configuring the default address selection policy table
.Pq RFC 3484 .
The default value is
.Dq Li YES ,
and the policy table to be installed is specified by the
.Va ip6addrctl_policy
variable below.
.It Va ip6addrctl_policy
.Pq Vt str
This variable specifies the policy table to be installed,
and can be one of the following keywords:
.Dq Li ipv4_prefer ,
.Dq Li ipv6_prefer ,
or
.Dq Li AUTO
(default).
.Pp
If
.Dq Li ipv4_prefer
or
.Dq Li ipv6_prefer
is specified,
.Xr ip6addrctl 8
installs a pre-defined policy table described in Section 2.1
.Pq IPv6-preferred
or 10.3
.Pq IPv4-preferred
of RFC 3484.
.Pp
If
.Dq Li AUTO
is specified, it attempts to read a file
.Pa /etc/ip6addrctl.conf
first.
If this file is found,
.Xr ip6addrctl 8
reads and installs it.
If not found, a policy is automatically set
according to
.Va ipv6_enable
variable; if the variable is set to
.Dq Li YES
the IPv6-preferred one is used.
Otherwise IPv4-preferred.
.It Va ip6addrctl_verbose
.Pq Vt bool
If set to
.Dq Li YES ,
print the installed policy table after configuring.
The default value is
.Dq Li NO .

.Va cloned_interfaces
are automatically appended to
.Va network_interfaces
for configuration.
.It Va gif_interfaces
.Pq Vt str
Set to the list of
.Xr gif 4
tunnel interfaces to configure on this host.
A
.Va gifconfig_ Ns Aq Ar interface
variable is assumed to exist for each value of
