rc.conf(5)

NAME

     rc.conf -- system configuration information

DESCRIPTION

     The file rc.conf 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 rc.conf file is generally initialized by the system
     installation utility, sysinstall(8).

     The purpose of rc.conf is not to run commands or perform system startup
     actions directly.	Instead, it is included by the various generic startup
     scripts in /etc which conditionalize their internal actions according to
     the settings found there.

     The /etc/rc.conf file is included from the file /etc/defaults/rc.conf,
     which specifies the default settings for all the available options.
     Options need only be specified in /etc/rc.conf when the system adminis-
     trator wishes to override these defaults.	The file /etc/rc.conf.local is
     used to override settings in /etc/rc.conf for historical reasons.	See
     the rc_conf_files variable below.

     The following list provides a name and short description for each vari-
     able that can be set in the rc.conf file:

     rc_debug	 (bool) If set to ``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
		 syslog(3).

     rc_info	 (bool) If set to ``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.

     swapfile	 (str) If set to ``NO'', no swapfile is installed, otherwise
		 the value is used as the full pathname to a file to use for
		 additional swap space.

     apm_enable  (bool) If set to ``YES'', enable support for Automatic Power
		 Management with the apm(8) command.

     apmd_enable
		 (bool) Run apmd(8) to handle APM event from userland.	This
		 also enables support for APM.

     apmd_flags  (str) If apmd_enable is set to ``YES'', these are the flags
		 to pass to the apmd(8) daemon.

     devd_enable
		 (bool) Run devd(8) to handle device added, removed or unknown
		 events from the kernel.

     kldxref_enable
		 (bool) Set to ``NO'' by default.  Set to ``YES'' to automati-
		 cally rebuild linker.hints files with kldxref(8) at boot
     kldxref_module_path
		 (str) Empty by default.  A semi-colon (`;') delimited list of
		 paths containing kld(4) modules.  If empty, the contents of
		 the kern.module_path sysctl(8) are used.

     pccard_enable
		 (bool) If set to ``YES'', enable PCCARD support at boot time.

     pccard_mem  (str) Set to PCCARD controller memory address or ``DEFAULT''
		 for the default value.

     pccard_ifconfig
		 (str) List of arguments to be passed to ifconfig(8) at boot
		 time or on insertion of the card (e.g. ``inet 192.168.1.1
		 netmask 255.255.255.0'' for a fixed address or ``DHCP'' for a
		 DHCP client).

     pccard_beep
		 (int) If 0, set the PCCARD controller to silent mode.	If 1,
		 set it to beep mode.  If 2, set it to melody mode.

     pccard_conf
		 (str) Path to the configuration file for the pccardd(8) dae-
		 mon (e.g. /etc/pccard.conf.sample).

     pccardd_flags
		 (str) If pccard_enable is set to ``YES'', these are the flags
		 to pass to the pccardd(8) daemon.

     pccard_ether_delay
		 (str) Set the delay before starting dhclient(8) in the
		 /etc/pccard_ether script.  This defaults to 5 seconds to work
		 around a bug in the ed(4) driver which can lead to system
		 hangs when using some newer ed(4) based cards.

     removable_interfaces
		 (str) List of removable network interfaces to be supported by
		 /etc/pccard_ether.

     tmpmfs	 Controls the creation of a /tmp memory file system.  Always
		 happens if set to ``YES'' and never happens if set to ``NO''.
		 If set to anything else, a memory file system is created if
		 /tmp is not writable.

     tmpsize	 Controls the size of a created /tmp memory file system.

     tmpmfs_flags
		 Extra options passed to the mdmfs(8) utility when the memory
		 file system for /tmp is created.  The default is ``-S'',
		 which inhibits the use of softupdates on /tmp to waste as
		 little space as possible.  See mdmfs(8) for other options you
		 can use in tmpmfs_flags.

     varmfs	 Controls the creation of a /var memory file system.  Always
		 happens if set to ``YES'' and never happens if set to ``NO''.
		 If set to anything else, a memory file system is created if
		 /var is not writable.


     populate_var
		 Controls the automatic population of the /var file system.
		 Always happens if set to ``YES'' and never happens if set to
		 ``NO''.  If set to anything else, a memory file system is
		 created if /var is not writable.  Note that this process
		 requires access to certain commands in /usr before /usr is
		 mounted on normal systems.

     local_startup
		 (str) List of directories to search for startup script files.

     script_name_sep
		 (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 spa-
		 ces.

     hostname	 (str) The fully qualified domain name (FQDN) of this host on
		 the network.  This should almost certainly be set to some-
		 thing meaningful, even if there is no network connection.  If
		 dhclient(8) is used to set the hostname via DHCP, this vari-
		 able should be set to an empty string.

     ipv6_enable
		 (bool) Enable support for IPv6 networking.  Note that this
		 requires that the kernel have been compiled with options
		 INET6.

     nisdomainname
		 (str) The NIS domain name of this host, or ``NO'' if NIS is
		 not used.

     dhclient_program
		 (str) Path to the DHCP client program (/sbin/dhclient, the
		 ISC DHCP client, is the default).

     dhclient_flags
		 (str) Additional flags to pass to the DHCP client program.
		 For the ISC DHCP client, see the dhclient(8) manpage for a
		 description of the command line options available.

     background_dhclient
		 (bool) Set to ``YES'' to start the dhcp client in background.
		 This can cause trouble with applications depending on a work-
		 ing network, but it will provide a faster startup in many
		 cases.

     firewall_enable
		 (bool) Set to ``YES'' to load firewall rules at startup.  If
		 the kernel was not built with options IPFIREWALL, the ipfw.ko
		 kernel module will be loaded.	See also ipfilter_enable.

     ipv6_firewall_enable
		 (bool) The IPv6 equivalent of firewall_enable.  Set to
		 ``YES'' to load IPv6 firewall rules at startup.  If the ker-
		 nel was not built with options IPV6FIREWALL, the ip6fw.ko

     firewall_type
		 (str) Names the firewall type from the selection in
		 /etc/rc.firewall, or the file which contains the local fire-
		 wall ruleset.	Valid selections from /etc/rc.firewall are:

		 open	 unrestricted IP access
		 closed  all IP services disabled, except via ``lo0''
		 client  basic protection for a workstation
		 simple  basic protection for a LAN.

		 If a filename is specified, the full path must be given.

     ipv6_firewall_type
		 (str) The IPv6 equivalent of firewall_type.

     firewall_quiet
		 (bool) Set to ``YES'' to disable the display of firewall
		 rules on the console during boot.

     ipv6_firewall_quiet
		 (bool) The IPv6 equivalent of firewall_quiet.

     firewall_logging
		 (bool) Set to ``YES'' to enable firewall event logging.  This
		 is equivalent to the IPFIREWALL_VERBOSE kernel option.

     ipv6_firewall_logging
		 (bool) The IPv6 equivalent of firewall_logging.

     firewall_flags
		 (str) Flags passed to ipfw(8) if firewall_type specifies a
		 filename.

     ipv6_firewall_flags
		 (str) The IPv6 equivalent of firewall_flags.

     natd_program
		 (str) Path to natd(8).

     natd_enable
		 (bool) Set to ``YES'' to enable natd(8).  firewall_enable
		 must also be set to ``YES'', and divert(4) sockets must be
		 enabled in the kernel.  If the kernel was not built with
		 options IPDIVERT, the ipdivert.ko kernel module will be
		 loaded.

     natd_interface
		 (str) This is the name of the public interface on which
		 natd(8) should run.  The interface may be given as an inter-
		 face name or as an IP address.

     natd_flags  (str) Additional natd(8) flags should be placed here.	The -n
		 or -a flag is automatically added with the above
		 natd_interface as an argument.

     ipfilter_enable
		 (bool) Set to ``NO'' by default.  Setting this to ``YES''

		 into /etc/rc.conf and editing /etc/ipf.rules and
		 /etc/ipnat.rules appropriately.

		 Note that ipfilter_enable and ipnat_enable can be enabled
		 independently.  ipmon_enable and ipfs_enable both require at
		 least one of ipfilter_enable and ipnat_enable to be enabled.

		 Having

		 options IPFILTER
		 options IPFILTER_LOG
		 options IPFILTER_DEFAULT_BLOCK

		 in the kernel configuration file is a good idea, too.

     ipfilter_program
		 (str) Path to ipf(8) (default /sbin/ipf).

     ipfilter_rules
		 (str) Set to /etc/ipf.rules by default.  This variable con-
		 tains the name of the filter rule definition file.  The file
		 is expected to be readable for the ipf(8) command to execute.

     ipv6_ipfilter_rules
		 (str) Set to /etc/ipf6.rules by default.  This variable con-
		 tains the IPv6 filter rule definition file.  The file is
		 expected to be readable for the ipf(8) command to execute.

     ipfilter_flags
		 (str) Empty by default.  This variable contains flags passed
		 to the ipf(8) program.

     ipnat_enable
		 (bool) Set to ``NO'' by default.  Set it to ``YES'' to enable
		 ipnat(1) network address translation.	See ipfilter_enable
		 for a detailed discussion.

     ipnat_program
		 (str) Path to ipnat(1) (default /sbin/ipnat).

     ipnat_rules
		 (str) Set to /etc/ipnat.rules by default.  This variable con-
		 tains the name of the file holding the network address trans-
		 lation definition.  This file is expected to be readable for
		 the ipnat(1) command to execute.

     ipnat_flags
		 (str) Empty by default.  This variable contains flags passed
		 to the ipnat(1) program.

     ipmon_enable
		 (bool) Set to ``NO'' by default.  Set it to ``YES'' to enable
		 ipmon(8) monitoring (logging ipf(8) and ipnat(1) events).
		 Setting this variable needs setting ipfilter_enable or
		 ipnat_enable too.  See ipfilter_enable for a detailed discus-
		 sion.

		 /etc/newsyslog.conf in such case like this:

		 /var/log/ipflog  640  10  100	*  Z  /var/run/ipmon.pid

     ipfs_enable
		 (bool) Set to ``NO'' by default.  Set it to ``YES'' to enable
		 ipfs(8) saving the filter and NAT state tables during shut-
		 down and reloading them during startup again.	Setting this
		 variable needs setting ipfilter_enable or ipnat_enable to
		 ``YES'' too.  See ipfilter_enable for a detailed discussion.
		 Note that if kern_securelevel is set to 3, ipfs_enable cannot
		 be used because the raised securelevel will prevent ipfs(8)
		 from saving the state tables at shutdown time.

     ipfs_program
		 (str) Path to ipfs(8) (default /sbin/ipfs).

     ipfs_flags  (str) Empty by default.  This variable contains flags passed
		 to the ipfs(8) program.

     pf_enable	 (bool) Set to ``NO'' by default.  Setting this to ``YES''
		 enables pf(4) packet filtering.

		 Typical usage will require putting

		       pf_enable="YES"

		 into /etc/rc.conf and editing /etc/pf.conf appropriately.

		       device pf

		 builds pf(4) into the kernel.	Otherwise it is loaded from a
		 module.

     pf_rules	 (str) Path to pf(4) ruleset configuration file (default
		 /etc/pf.conf).

     pf_program  (str) Path to pfctl(8) (default /sbin/pfctl).

     pf_flags	 (str) If pf_enable is set to ``YES'', these flags are passed
		 to the pfctl(8) program when loading the ruleset.

     pflog_enable
		 (bool) Set to ``NO'' by default.  Setting this to ``YES''
		 enables pflogd(8) which logs packtes from the pf(4) packet
		 filter.

     pflog_logfile
		 (str) If pflog_enable is set to ``YES'' this controls where
		 pflogd(8) stores the logfile (default /var/log/pflog).  Check
		 /etc/newsyslog.conf to adjust logfile rotation for this.

     pflog_program
		 (str) Path to pflogd(8) (default /sbin/pflogd).

     pflog_flags
		 (str) Empty by default.  This variable contains additional
		 flags passed to the pflogd(8) program.

     log_in_vain
		 (int) Set to 0 by default.  The sysctl(8) variables,
		 net.inet.tcp.log_in_vain and net.inet.udp.log_in_vain, as
		 described in tcp(4) and udp(4), are set to the given value.

     tcp_keepalive
		 (bool) Set to ``YES'' by default.  Setting to ``NO'' will
		 disable probing idle TCP connections to verify that the peer
		 is still up and reachable.

     tcp_drop_synfin
		 (bool) Set to ``NO'' by default.  Setting to ``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 TCP_DROP_SYNFIN
		 option.

     icmp_drop_redirect
		 (bool) Set to ``NO'' by default.  Setting to ``YES'' will
		 cause the kernel to ignore ICMP REDIRECT packets.  Refer to
		 icmp(4) for more information.

     icmp_log_redirect
		 (bool) Set to ``NO'' by default.  Setting to ``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 icmp(4) for
		 more information.

     icmp_bmcastecho
		 (bool) Set to ``YES'' to respond to broadcast or multicast
		 ICMP ping packets.  Refer to icmp(4) for more information.

     ip_portrange_first
		 (int) If not set to ``NO'', this is the first port in the
		 default portrange.  Refer to ip(4) for more information.

     ip_portrange_last
		 (int) If not set to ``NO'', this is the last port in the
		 default portrange.  Refer to ip(4) for more information.

     network_interfaces
		 (str) Set to the list of network interfaces to configure on
		 this host.  For example, if the only network devices in the
		 system are the loopback device (lo0) and a NIC using the
		 ed(4) driver, this could be set to ``lo0 ed0''.  An
		 ifconfig_<interface> variable is also assumed to exist for
		 each value of interface.  It is also possible to add IP alias
		 entries here in cases where multiple IP addresses registered
		 against a single interface are desired.  Assuming that the
		 interface in question was ed0, it might look something like
		 this:

		 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
		 ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"

		 ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"

		 Then note that alias4 would not be added since the search
		 would stop with the missing alias3 entry.

		 If the /etc/start_if.<interface> file is present, it is read
		 and executed by the sh(1) interpreter before configuring the
		 interface as specified in the ifconfig_<interface> and
		 ifconfig_<interface>_alias<n> variables.

		 It is possible to bring up an interface with DHCP by setting
		 the ifconfig_<interface> variable to ``DHCP''.  For instance,
		 to initialize the ed0 device via DHCP, it is possible to use
		 something like:

		 ifconfig_ed0="DHCP"

		 It is also possible to rename interface by doing:

		 ifconfig_ed0_name="net0"
		 ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"

     ipv6_network_interfaces
		 (str) This is the IPv6 equivalent of network_interfaces.
		 Instead of setting the ifconfig variables as
		 ifconfig_<interface> they should be set as
		 ipv6_ifconfig_<interface>.  Aliases should be set as
		 ipv6_ifconfig_<interface>_alias<n>.  ipv6_prefix_<interface>
		 does something.  Interfaces that do not have a
		 ipv6_ifconfig_<interface> setting will be auto configured by
		 rtsol(8) if the ipv6_gateway_enable is set to ``NO''.	Note
		 that the IPv6 networking code does not support the
		 /etc/start_if.<interface> files.

     ipv6_default_interface
		 (str) If not set to ``NO'', this is the default output inter-
		 face for scoped addresses.  Now this works only for IPv6 link
		 local multicast addresses.

     cloned_interfaces
		 (str) Set to the list of clonable network interfaces to cre-
		 ate on this host.  Entries in cloned_interfaces are automati-
		 cally appended to network_interfaces for configuration.

     gif_interfaces
		 (str) Set to the list of gif(4) tunnel interfaces to config-
		 ure on this host.  A gifconfig_<interface> variable is
		 assumed to exist for each value of interface.	The value of
		 this variable is used to configure the link layer of the tun-
		 nel according to the syntax of the tunnel option to
		 ifconfig(8).  Additionally, this option ensures that each
		 listed interface is created via the create option to
		 ifconfig(8) before attempting to configure it.

     sppp_interfaces
		 (str) Set to the list of sppp(4) interfaces to configure on
		 this host.  A spppconfig_<interface> variable is assumed to
		 exist for each value of interface.  Each interface should
		 the manual for a full description.

     ppp_nat	 (bool) If set to ``YES'', enables network address transla-
		 tion.	Used in conjunction with gateway_enable allows hosts
		 on private network addresses access to the Internet using
		 this host as a network address translating router.

     ppp_profile
		 (str) The name of the profile to use from /etc/ppp/ppp.conf.

     ppp_user	 (str) The name of the user under which ppp(8) should be
		 started.  By default, ppp(8) is started as ``root''.

     rc_conf_files
		 (str) This option is used to specify a list of files that
		 will override the settings in /etc/defaults/rc.conf.  The
		 files will be read in the order in which they are specified
		 and should include the full path to the file.	By default,
		 the files specified are /etc/rc.conf and /etc/rc.conf.local

     gbde_autoattach_all
		 (bool) If set to ``YES'', /etc/rc.d/gbde will attempt to
		 automatically initialize your .bde devices in /etc/fstab.

     gbde_devices
		 (str) List the devices that the script should try to attach,
		 or ``AUTO''.

     gbde_lockdir
		 (str) The directory where the gbde(4) lockfiles are located.
		 The default lockfile directory is /etc.

		 The lockfile for each individual gbde(4) device can be over-
		 ridden by setting the variable gbde_lock_<device>, where
		 device is the encrypted device without the ``/dev/'' and
		 ``.bde'' parts.

     gbde_attach_attempts
		 (int) Number of times to attempt attaching to a gbde(4)
		 device, i.e., how many times the user is asked for the pass-
		 phrase.  Default is 3.

     gbde_swap_enable
		 (bool) If set to ``YES'', any .bde swap devices listed in
		 /etc/fstab will be initialized with a random, one-shot key.
		 Note that this makes recovery of kernel dumps impossible.

     root_rw_mount
		 (bool) Set to ``YES'' by default.  After the file systems are
		 checked at boot time, the root file system is remounted as
		 read-write if this is set to ``YES''.	Diskless systems that
		 mount their root file system from a read-only remote NFS
		 share should set this to ``NO'' in their rc.conf.

     fsck_y_enable
		 (bool) If set to ``YES'', fsck(8) will be run with the -y
		 flag if the initial preen of the file systems fails.

		 I/O bandwidth is monopolized by fsck(8).

     netfs_types
		 (str) List of file system types that are network-based.  This
		 list should generally not be modified by end users.  Use
		 extra_netfs_types instead.

     extra_netfs_types
		 (str) If set to something other than ``NO'' (the default),
		 this variable extends the list of file system types for which
		 automatic mounting at startup by rc(8) should be delayed
		 until the network is initialized.  It should contain a white-
		 space-separated list of network file system descriptor pairs,
		 each consisting of a file system type as passed to mount(8)
		 and a human-readable, one-word description, joined with a
		 colon (`:').  Extending the default list in this way is only
		 necessary when third party file system types are used.

     syslogd_enable
		 (bool) If set to ``YES'', run the syslogd(8) daemon.

     syslogd_program
		 (str) Path to syslogd(8) (default /usr/sbin/syslogd).

     syslogd_flags
		 (str) If syslogd_enable is set to ``YES'', these are the
		 flags to pass to syslogd(8).

		 (bool) If set to ``YES'', run the inetd(8) daemon.

     inetd_program
		 (str) Path to inetd(8) (default /usr/sbin/inetd).

     inetd_flags
		 (str) If inetd_enable is set to ``YES'', these are the flags
		 to pass to inetd(8).

		 (bool) If set to ``YES'', run the named(8) daemon.

     named_program
		 (str) Path to named(8) (default /usr/sbin/named).

     named_flags
		 (str) If named_enable is set to ``YES'', these are the flags
		 to pass to named(8).

     named_pidfile
		 (str) This is the default path to the named(8) daemon's PID
		 file.	Change it if you change the location in named.conf(5).

     named_chrootdir
		 (str) The root directory for a name server run in a chroot(8)
		 environment (default /var/named).  If left empty named(8)
		 will not be run in a chroot(8) environment.

     named_chroot_autoupdate

		 (bool) Set to ``YES'' to start a Kerberos 5 authentication
		 server at boot time.

     kerberos5_server
		 (str) If kerberos5_server_enable is set to ``YES'' this is
		 the path to Kerberos 5 Authentication Server.

     kadmind5_server_enable
		 (bool) Set to ``YES'' to start kadmind(8), the Kerberos 5
		 Administration Daemon; set to ``NO'' on a slave server.

     kadmind5_server
		 (str) If kadmind5_server_enable is set to ``YES'' this is the
		 path to Kerberos 5 Administration Daemon.

     kpasswdd_server_enable

		 path to Kerberos 5 Password-Changing Daemon.

     rwhod_enable
		 (bool) If set to ``YES'', run the rwhod(8) daemon at boot
		 time.

     rwhod_flags
		 (str) If rwhod_enable is set to ``YES'', these are the flags

     amd_enable  (bool) If set to ``YES'', run the amd(8) daemon at boot time.

     amd_flags	 (str) If amd_enable is set to ``YES'', these are the flags to
		 pass to it.  See the amd(8) manpage for more information.

     amd_map_program
		 (str) If set, the specified program is run to get the list of
		 amd(8) maps.  For example, if the amd(8) maps are stored in
		 NIS, one can set this to run ypcat(1) to get a list of amd(8)
		 maps from the amd.master NIS map.

     update_motd
		 (bool) If set to ``YES'', /etc/motd will be updated at boot
		 time to reflect the kernel release being run.	If set to
		 ``NO'', /etc/motd will not be updated.

     nfs_client_enable
		 (bool) If set to ``YES'', run the NFS client daemons at boot
		 time.

     nfs_access_cache
		 (int) If nfs_client_enable is set to ``YES'', this can be set
		 to ``0'' to disable NFS ACCESS RPC caching, or to the number
		 of seconds for which NFS ACCESS results should be cached.  A
		 value of 2-10 seconds will substantially reduce network traf-
		 fic for many NFS operations.

     mountd_enable
		 (bool) If set to ``YES'', and no nfs_server_enable is set,
		 start mountd(8), but not nfsd(8) daemon.  It is commonly
		 needed to run CFS without real NFS used.

		 secure port.

     nfs_bufpackets
		 (int) If set to a number, indicates the number of packets
		 worth of socket buffer space to reserve on an NFS client.
		 The kernel default is typically 4.  Using a higher number may
		 be useful on gigabit networks to improve performance.	The
		 minimum value is 2 and the maximum is 64.

     rpc_lockd_enable
		 (bool) If set to ``YES'' and also an NFS server, run
		 rpc.lockd(8) at boot time.

     rpc_statd_enable
		 (bool) If set to ``YES'' and also an NFS server, run
		 rpc.statd(8) at boot time.

     rpcbind_program
		 (str) Path to rpcbind(8) (default /usr/sbin/rpcbind).

     rpcbind_enable
		 (bool) If set to ``YES'', run the rpcbind(8) service at boot
		 time.

		 (str) Optional arguments passed to newfs(8) to initialize
		 ramdisk X.

     ramdisk_<X>_owner
		 (str) An ownership specification passed to chown(8) after the
