RC.CONF(5) MidnightBSD 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, 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 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.

Options are set with ‘‘name=value’’ assignments that use sh(1) syntax. 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 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.

early_late_divider

(str) The name of the script that should be used as the delimiter between the ‘‘early’’ and ‘‘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 local_startup variable (see below). Thus, the two likely candidates for this value are mountcritlocal for the typical system, and mountcritremote if the system needs remote file systems mounted to get access to the local_startup directories; for example when /usr/local is NFS mounted. For rc.conf within a jail(8) 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).

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 automatically rebuild linker.hints files with kldxref(8) at boot time.

kldxref_clobber

(bool) Set to ‘‘NO’’ by default. If kldxref_enable is true, setting to ‘‘YES’’ will overwrite existing linker.hints files at boot time. Otherwise, only missing linker.hints files are generated.

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_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.

powerd_enable

(bool) If set to ‘‘YES’’, enable the system power control facility with the powerd(8) daemon.

powerd_flags

(str) If powerd_enable is set to ‘‘YES’’, these are the flags to pass to the powerd(8) daemon.

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 -M’’, which inhibits the use of softupdates on /tmp to waste as little space as possible and creates a pure memory backed disk, which will never be swapped out, for maximum performance and system stability at low memory conditions. 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 -M’’, which inhibits the use of softupdates on /var to waste as little space as possible and creates a pure memory backed disk, which will never be swapped out, for maximum performance and system stability at low memory conditions. See mdmfs(8) for other options you can use in varmfs_flags.

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.

cleanvar_enable

(bool) Clean the /var directory.

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.

hostapd_enable

(bool) Set to ‘‘YES’’ to start hostapd(8) at system boot time.

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 requires that the kernel has 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 OpenBSD DHCP client, is the default).

dhclient_flags

(str) Additional flags to pass to the DHCP client program. For the OpenBSD 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 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 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 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 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.

ipv6_ipfilter_rules

(str) Set to /etc/ipf6.rules by default. This variable contains 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(8) network address translation. See ipfilter_enable for a detailed discussion.

ipnat_program

(str) Path to ipnat(8) (default /sbin/ipnat).

ipnat_rules

(str) Set to /etc/ipnat.rules by default. This variable contains the name of the file holding the network address translation definition. This file is expected to be readable for the ipnat(8) command to execute.

ipnat_flags

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

ipmon_enable

(bool) Set to ‘‘NO’’ by default. Set it to ‘‘YES’’ to enable ipmon(8) monitoring (logging ipf(8) and ipnat(8) 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 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 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 packets 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.

pfsync_enable

(bool) Set to ‘‘NO’’ by default. Setting this to ‘‘YES’’ enables exposing pf(4) state changes to other hosts over the network by means of pfsync(4). The pfsync_syncdev variable must also be set then.

pfsync_syncdev

(str) Empty by default. This variable specifies the name of the network interface pfsync(4) should operate through. It must be set accordingly if pfsync_enable is set to ‘‘YES’’.

pfsync_ifconfig

(str) Empty by default. This variable can contain additional options to be passed to the ifconfig(8) command used to set up pfsync(4).

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 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 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 or ‘‘AUTO’’ (the default) for all current interfaces. For example, if the only active 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. The variable can contain arguments to ifconfig(8), as well as special case-insensitive keywords described below. Such keywords are removed before passing the value to ifconfig(8) while the order of the other arguments is preserved.

One can configure more than one IPv4 address with the ipv4_addrs_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 ifconfig(8) alias section. With the interface in question being ed0, an example could look like:

ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"

It is also possible to add IP alias entries using ifconfig(8) syntax. 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"

And so on. For each ifconfig_

interface_aliasn〉 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. Due to this difficult to manage behavior, the ifconfig_

interface_aliasn〉 form is deprecated.

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_aliasn〉 variables.

If the ifconfig_interface〉 contains the keyword ‘‘NOAUTO’’ then the interface will not be configured at boot or by /etc/pccard_ether when network_interfaces is set to ‘‘AUTO’’.

It is possible to bring up an interface with DHCP by adding ‘‘DHCP’’ to the ifconfig_interface〉 variable. For instance, to initialize the ed0 device via DHCP, it is possible to use something like:

ifconfig_ed0="DHCP"

Also, if your interface needs WPA authentication, it is possible to add ‘‘WPA’’ to the ifconfig_interface〉 variable.

Finally, you can add ifconfig(8) options in this variable, in addition to the /etc/start_if.interface〉 file. For instance, to initialize the wi0 device via DHCP, using WPA authentication and 802.11b mode, it is possible to use something like:

ifconfig_wi0="DHCP WPA mode 11b"

In addition to the ifconfig_interface〉 form, a fallback variable ifconfig_DEFAULT may be configured. It will be used for all interfaces with no ifconfig_interface〉 variable. This is intended to replace the no longer supported pccard_ifconfig variable.

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_aliasn〉. 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 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 exist 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_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 overridden 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.

geli_devices

(str) List of devices to automatically attach on boot. Note that .eli devices from /etc/fstab are automatically appended to this list.

geli_tries

(int) Number of times user is asked for the pass-phrase. If empty, it will be taken from kern.geom.eli.tries sysctl variable.

geli_default_flags

(str) Default flags to use by geli(8) when configuring disk encryption. Flags can be configured for every device separately by defining geli_

device_flags variable.

geli_autodetach

(str) Specifies if GELI devices should be marked for detach on last close after file systems are mounted. Default is ‘‘YES’’. This can be changed for every device separately by defining geli_

device_autodetach variable.

geli_swap_flags

Options passed to the geli(8) utility when encrypted GEOM providers for swap partitions are created. The default is ‘‘-a aes -l 256 -s 4096 -d’’.

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 automatic mounting at startup by rc(8) should be delayed until the network is initialized. It should contain a whitespace-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.

rcshutdown_timeout

(int) If set, start a watchdog timer in the background which will terminate rc.shutdown if shutdown(8) has not completed within the specified time (in seconds). Notice that in addition to this soft timeout, init(8) also applies a hard timeout for the execution of rc.shutdown. This is configured via sysctl(8) variable kern.init_shutdown_timeout and defaults to 120 seconds. Setting the value of rcshutdown_timeout to more than 120 seconds will have no effect until the sysctl(8) variable kern.init_shutdown_timeout is also increased.
