RC.CONF(5)		       File Formats Manual		      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 instal-
     lations, the rc.conf file is generally initialized by the system  installa-
     tion utility, sysinstall(8).

     The purpose of rc.conf is not to run commands or perform system startup ac-
     tions  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.   Op-
     tions  need only be specified in /etc/rc.conf when the system administrator
     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	variable
     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 pro-
		 duces 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 condi-
		 tion  that is not serious enough to warrant a warning or an er-
		 ror 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 addi-
		 tional swap space.

     apm_enable  (bool) If set to "YES", enable support for Automatic Power Man-
		 agement 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 automatically
		 rebuild linker.hints files with kldxref(8) at boot time.

     kldxref_clobber
		 (bool) Set to "NO" by default.  If kldxref_enable is true, set-
		 ting to "YES" will overwrite  existing  linker.hints  files  at
		 boot time.  Otherwise, only missing linker.hints files are gen-
		 erated.

     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)  daemon
		 (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.

     varsize	 Controls the size of a created /var memory file system.

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

     populate_var
		 Controls the automatic population of the /var file system.  Al-
		 ways  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 spaces.

     hostname	 (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
		 dhclient(8) is used to set the hostname via DHCP, this variable
		 should be set to an empty string.

     ipv6_enable
		 (bool) Enable support for IPv6 networking.  Note that this  re-
		 quires 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 descrip-
		 tion 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 working
		 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 ker-
		 nel 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	kernel	was  not
		 built	with  options  IPV6FIREWALL,  the ip6fw.ko kernel module
		 will be loaded.

     firewall_script
		 (str) This variable specifies the full  path  to  the	firewall
		 script to run.  The default is /etc/rc.firewall.

     ipv6_firewall_script
		 (str) The IPv6 equivalent of firewall_script.

     firewall_type
		 (str)	 Names	 the   firewall   type	from  the  selection  in
		 /etc/rc.firewall, or the file which contains the local firewall
		 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 interface 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" enables
		 ipf(8) packet filtering.

		 Typical usage will require putting

		 ipfilter_enable="YES"
		 ipnat_enable="YES"
		 ipmon_enable="YES"
		 ipfs_enable="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 inde-
		 pendently.   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 contains
		 the name of the filter rule definition file.  The file  is  ex-
		 pected 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  ex-
		 pected 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 ip-
		 nat(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 transla-
		 tion 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 ip-
		 mon(8) monitoring (logging ipf(8) and ipnat(1)  events).   Set-
		 ting	this   variable   needs   setting   ipfilter_enable   or
		 ipnat_enable too.  See ipfilter_enable for a  detailed  discus-
		 sion.

     ipmon_program
		 (str) Path to ipmon(8) (default /sbin/ipmon).

     ipmon_flags
		 (str)	Set  to  "-Ds" by default.  This variable contains flags
		 passed to the ipmon(8) program.  Another typical example  would
		 be "-D /var/log/ipflog" to have ipmon(8) log directly to a file
		 bypassing  syslogd(8).  Make sure to adjust /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 shutdown
		 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  be-
		 cause	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.

     tcp_extensions
		 (bool) Set to "YES" by default.  Setting this to "NO"	disables
		 certain  TCP options as described by RFC 1323.  Setting this to
		 "NO" might help remedy such problems with connections	as  ran-
		 domly	hanging  or  other weird behavior.  Some network devices
		 are known to be broken with respect to these options.

     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 de-
		 scribed 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 mes-
		 sages are not rate-limited, so this option should only be  used
		 for troubleshooting networks.	Refer to icmp(4) for more infor-
		 mation.

     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 en-
		 tries here in cases  where  multiple  IP  addresses  registered
		 against  a single interface are desired.  Assuming that the in-
		 terface 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"

		 And so on.  For each ifconfig_<interface>_alias<n>  entry  that
		 is  found,  its  contents are passed to ifconfig(8).  Execution
		 stops at the first unsuccessful access, so  if  something  like
		 this is present:

		 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"

		 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 some-
		 thing 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.   In-
		 stead 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 config-
		 ured 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  interface
		 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  create
		 on  this  host.  Entries in cloned_interfaces are automatically
		 appended to network_interfaces for configuration.

     gif_interfaces
		 (str) Set to the list of gif(4) tunnel interfaces to  configure
		 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 tunnel 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 ex-
		 ist for each value of interface.  Each interface should also be
		 configured by a general ifconfig_<interface> setting.	Refer to
		 spppcontrol(8) for more information about available options.

     ppp_enable  (bool) If set to "YES", run the ppp(8) daemon.

     ppp_mode	 (str)	Mode  in which to run the ppp(8) daemon.  Accepted modes
		 are "auto", "ddial", "direct" and "dedicated".  See the  manual
		 for a full description.

     ppp_nat	 (bool)  If  set  to "YES", enables network address translation.
		 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 in-
		 clude	the full path to the file.  By default, the files speci-
		 fied are /etc/rc.conf and /etc/rc.conf.local

     gbde_autoattach_all
		 (bool) If set to "YES", /etc/rc.d/gbde will attempt to automat-
		 ically 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 overrid-
		 den 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.

     background_fsck
		 (bool) If set to "YES", the system will attempt to run  fsck(8)
		 in the background where possible.

     background_fsck_delay
		 (int)	The amount of time in seconds to sleep before starting a
		 background fsck(8).  It defaults  to  sixty  seconds  to  allow
		 large	applications  such  as the X server to start before disk
		 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 auto-
		 matic mounting at startup by rc(8) should be delayed until  the
		 network  is  initialized.  It should contain a whitespace-sepa-
		 rated list of network file system descriptor pairs,  each  con-
		 sisting  of  a file system type as passed to mount(8) and a hu-
		 man-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).

     inetd_enable

		 client of the mouse (such as an X  server)  should  access  the
		 mouse through the virtual mouse device, /dev/sysmouse, and con-
		 figure  it  as a "sysmouse" type mouse, since all mouse data is
		 converted to this single canonical format when using moused(8).
		 If the client program does not  support  the  "sysmouse"  type,
		 specify  the  "mousesystems"  type.  It is the second preferred
		 type.
