RC.CONF(5)                FreeBSD 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
     installations, the rc.conf file is generally initialized by the system
     installation utility: /stand/sysinstall.

     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'' option below.

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

     swapfile      (str) If set to ``NO'' then no swapfile is installed, oth-
                   erwise 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 enable support for APM.

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

     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.

     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
                   pccard_ether(8) 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.

     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 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.

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

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

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

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

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

     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 pro-
                   tection for a workstation; ``simple'' - basic protection
                   for a LAN.  If a filename is specified, the full path must
                   be given.

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

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

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

     natd_program  (str) Path to natd(8).

     natd_enable   (bool) Set to ``YES'' to enable natd.  firewall_enable must
                   also be set to ``YES'', and divert(4) sockets must be
                   enabled in the kernel.

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

     natd_flags    (str) Additional natd 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
                   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
                   contains the name of the 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 vari-
                   able contains the name of the file holding the network
                   address translation 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 discussion.

     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 dur-
                   ing shutdown and reloading them during startup again.  Set-
                   ting 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.

     tcp_extensions
                   (bool) Set to ``YES'' by default.  Setting this to NO dis-
                   ables certain TCP options as described by RFC 1323.  Set-
                   ting this to ``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.

     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 dis-
                   able 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.

     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.

     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
                   ed0 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 entires here in cases where multiple IP addresses
                   registered against a single interface are desired.  Assum-
                   ing 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"

                   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.

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

                   ifconfig_ed0="DHCP"

     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 configura-
                   tion.

     gif_interfaces
                   (str) Set to the list of gif(4) tunnel interfaces to con-
                   figure 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).  Additionaly, this option ensures that each
                   listed interface is created via the create option to
                   ifconfig(8) before attempting to configure it.

     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 packet aliasing.  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 should be
                   started.  By default, ppp is started as ``root''.

     ike_enable    (bool) If set to ``YES'', run an Internet Key Exchange
                   (IKE) daemon of some sort, based on the settings of
                   ike_program and ike_flags.

     ike_program   (str) If ike_enable is set to ``YES'', this is the name of
                   the IKE daemon to use.  The default is
                   /usr/local/sbin/isakmpd.

     ike_flags     (str) If ike_enable is set to ``YES'', these are the flags
                   to pass to the IKE daemon.

     ipsec_enable  (bool) Set to ``YES'' to run setkey(8) on ipsec_file at
                   boot time.

     ipsec_file    (str) Configuration file for setkey(8).

     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

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

     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

     font8x8       (str) If set to ``NO'' then the default 8x8 font value is
                   used for screen size requests, otherwise the value in
                   /usr/share/syscons/fonts/_value_ is used.

     blanktime     (int) If set to ``NO'' then the default screen blanking
                   interval is used, otherwise it is set to value seconds.

     saver         (str) If not set to ``NO'', this is the actual screen saver
                   to use (blank, snake, daemon, etc).

     moused_enable
                   (str) If set to ``YES'', the moused(8) daemon is started
                   for doing cut/paste selection on the console.

     moused_type   (str) This is the protocol type of the mouse connected to
                   this host.  This variable must be set if moused_enable is
                   set to ``YES''.  The moused(8) daemon is able to detect the
                   appropriate mouse type automatically in many cases.  Set
                   this variable to ``auto'' to let the daemon detect it, or
                   select one from the following list if the automatic detec-
                   tion fails.

                   If the mouse is attached to the PS/2 mouse port, choose
                   ``auto'' or ``ps/2'', regardless of the brand and model of
                   the mouse.  Likewise, if the mouse is attached to the bus
                   mouse port, choose ``auto'' or ``busmouse''.  All other
                   protocols are for serial mice and will not work with the
                   PS/2 and bus mice.  If this is a USB mouse, ``auto'' is the
                   only protocol type which will work.

                   Even if the mouse is not in the above list, it may be com-
                   patible with one in the list.  Refer to the man page for
                   moused(8) for compatibility information.

                   It should also be noted that while this is enabled, any
                   other client of the mouse (such as an X server) should
                   access the mouse through the virtual mouse device:
                   /dev/sysmouse and configure 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.

     moused_port   (str) If moused_enable is set to ``YES'', this is the
                   actual port the mouse is on.  It might be /dev/cuaa0 for a
                   COM1 serial mouse, /dev/psm0 for a PS/2 mouse or /dev/mse0
                   for a bus mouse, for example.

     moused_flags  (str) If moused_type is set, these are the additional flags
                   to pass to the moused(8) daemon.

     allscreens_flags
                   (str) If set, vidcontrol(1) is run with these options for
                   each of the virtual terminals (/dev/ttyv*).  For example,
                   ``-m on'' will enable the mouse pointer on all virtual ter-
                   minals if moused_enable is set to ``YES''.

                   system boot time.

     cron_program  (str) Path to cron(8) (default /usr/sbin/cron).

     cron_flags    (str) If cron_enable is set to ``YES'', these are the flags
                   to pass to cron(8).

     lpd_program   (str) Path to lpd(8) (default /usr/sbin/lpd).

     lpd_enable    (bool) If set to ``YES'' then run the lpd(8) daemon at sys-
                   tem boot time.

     lpd_flags     (str) If lpd_enable is set to ``YES'', these are the flags
                   to pass to the lpd(8) daemon.

     mta_start_script
                   (str) This variable specifies the full path to the script
                   to run to start a mail transfer agent.  The default is
                   /etc/rc.sendmail.  The sendmail_* variables which
                   /etc/rc.sendmail uses are documented in the rc.sendmail(8)
                   man page.

     dumpdev       (str) Indicates the device (usually a swap partition) to
                   which a crash dump should be written in the event of a sys-
                   tem crash.  The value of this variable is passed as the
                   argument to dumpon(8).  To disable crash dumps, set this
                   variable to ``NO''.

     dumpdir       (str) When the system reboots after a crash and a crash
                   dump is found on the device specified by the dumpdev vari-
                   able, savecore(8) will save that crash dump and a copy of
                   the kernel to the directory specified by the dumpdir vari-
                   able.  The default value is ``/var/crash''.  Set to ``NO''
                   to not run savecore(8) at boot time when dumpdir is set.

     savecore_flags
                   (str) If crash dumps are enabled, these are the flags to
                   pass to the savecore(8) utility.

     enable_quotas
                   (bool) Set to ``YES'' to turn on user disk quotas on system
                   startup via the quotaon(8) command.

                   ``YES'', this specifies a list of additional iBCS2 loaders
                   to enable.

     linux_enable  (bool) Set to ``YES'' to enable Linux/ELF binary emulation
                   at system initial boot time.

     osf1_enable   (bool) Set to ``YES'' to enable OSF/1 (Digital UNIX) binary
                   emulation at system initial boot time.  (alpha)

                   creation (see the man page for rndcontrol(8)).

     clear_tmp_enable
                   (bool) Set to ``YES'' to have /tmp cleaned at startup.

     ldconfig_paths
                   (str) Set to the list of shared library paths to use with
                   ldconfig(8).  NOTE: /usr/lib will always be added first, so
                   it need not appear in this list.

     ldconfig_insecure
                   (bool) The ldconfig(8) utility normally refuses to use
                   directories which are writable by anyone except root.  Set
                   this variable to ``YES'' to disable that security check
                   during system startup.

     kern_securelevel_enable
                   (bool) Set to ``YES'' to set the kernel security level at
                   system startup.

     kern_securelevel
                   (int) The kernel security level to set at startup.  The
                   allowed range of value ranges from -1 (the compile time
                   default) to 3 (the most secure).  See init(8) for the list
                   of possible security levels and their effect on system
                   operation.

                   not be printed.  (alpha)

     isdn_enable   (bool) Set to ``NO'' by default.  When set to ``YES'',
                   starts the isdn daemon /usr/sbin/isdnd at system boot time.

     isdn_flags    (str) Set to ``-dn -d0x1f9'' by default.  Additional flags
                   to pass to isdnd(8) (but see isdn_fsdev and isdn_ttype for
                   certain tunable parameters).

     isdn_ttype    (str) Set to ``cons25'' by default.  The terminal type of
                   the output device when isdnd(8) operates in fullscreen
