In new installations, the .Nm file is generally initialized by the system installation utility, .Xr sysinstall 8 . .Pp The purpose of .Nm is not to run commands or perform system startup actions directly. Instead, it is included by the various generic startup scripts in .Pa /etc which conditionalize their internal actions according to the settings found there. .Pp The .Pa /etc/rc.conf file is included from the file .Pa /etc/defaults/rc.conf , which specifies the default settings for all the available options. Options need only be specified in .Pa /etc/rc.conf when the system administrator wishes to override these defaults. The file .Pa /etc/rc.conf.local is used to override settings in .Pa /etc/rc.conf for historical reasons. See the .Va rc_conf_files variable below. .Pp The following list provides a name and short description for each variable that can be set in the .Nm file: .Bl -tag -width indent-two .It Va swapfile .Pq Vt str If set to .Dq Li NO , no swapfile is installed, otherwise the value is used as the full pathname to a file to use for additional swap space. .It Va apm_enable .Pq Vt bool If set to .Dq Li YES , enable support for Automatic Power Management with the .Xr apm 8 command. .It Va apmd_enable .Pq Vt bool Run .Xr apmd 8 to handle APM event from userland. This also enables support for APM. .It Va apmd_flags .Pq Vt str If .Va apmd_enable is set to .Dq Li YES , these are the flags to pass to the .Xr apmd 8 daemon. .It Va devd_enable .Pq Vt bool Run .Xr devd 8 to handle device added, removed or unknown events from the kernel. .It Va pccard_enable .Pq Vt bool If set to .Dq Li YES , enable PCCARD support at boot time. .It Va pccard_mem .Pq Vt str Set to PCCARD controller memory address or .Dq Li DEFAULT for the default value. .It Va pccard_ifconfig .Pq Vt str List of arguments to be passed to .Xr ifconfig 8 at boot time or on insertion of the card (e.g.\& .Dq Cm inet Li 192.168.1.1 Cm netmask Li 255.255.255.0 for a fixed address or .Dq Li DHCP for a DHCP client). .It Va pccard_beep .Pq Vt int If 0, set the PCCARD controller to silent mode. If 1, set it to beep mode. If 2, set it to melody mode. .It Va pccard_conf .Pq Vt str Path to the configuration file for the .Xr pccardd 8 daemon (e.g.\& .Pa /etc/pccard.conf.sample ) . .It Va pccardd_flags .Pq Vt str If .Va pccard_enable is set to .Dq Li YES , these are the flags to pass to the .Xr pccardd 8 daemon. .It Va pccard_ether_delay .Pq Vt str Set the delay before starting .Xr dhclient 8 in .Xr pccard_ether 8 script. This defaults to 5 seconds to work around a bug in the .Xr ed 4 driver which can lead to system hangs when using some newer .Xr ed 4 based cards. .It Va removable_interfaces .Pq Vt str List of removable network interfaces to be supported by .Pa /etc/pccard_ether . .It Va local_startup .Pq Vt str List of directories to search for startup script files. .It Va script_name_sep .Pq Vt 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. .It Va hostname .Pq Vt 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 .Xr dhclient 8 is used to set the hostname via DHCP, this variable should be set to an empty string. .It Va nisdomainname .Pq Vt str The NIS domain name of this host, or .Dq Li NO if NIS is not used. .It Va dhcp_program .Pq Vt str Path to the DHCP client program .Pa ( /sbin/dhclient , the ISC DHCP client, is the default). .It Va dhcp_flags .Pq Vt str Additional flags to pass to the DHCP client program. For the ISC DHCP client, see the .Xr dhclient 8 manpage for a description of the command line options available. .It Va firewall_enable .Pq Vt bool Set to .Dq Li YES to load firewall rules at startup. If the kernel was not built with .Cd "options IPFIREWALL" , the .Pa ipfw.ko kernel module will be loaded. See also .Va ipfilter_enable . .It Va firewall_script .Pq Vt str This variable specifies the full path to the firewall script to run. The default is .Pa /etc/rc.firewall . .It Va firewall_type .Pq Vt str Names the firewall type from the selection in .Pa /etc/rc.firewall , or the file which contains the local firewall ruleset. Valid selections from .Pa /etc/rc.firewall are: .Pp .Bl -tag -width ".Li simple" -compact .It Li open unrestricted IP access .It Li closed all IP services disabled, except via .Dq Li lo0 .It Li client basic protection for a workstation .It Li simple basic protection for a LAN. .El .Pp If a filename is specified, the full path must be given. .It Va firewall_quiet .Pq Vt bool Set to .Dq Li YES to disable the display of firewall rules on the console during boot. .It Va firewall_logging .Pq Vt bool Set to .Dq Li YES to enable firewall event logging. This is equivalent to the .Dv IPFIREWALL_VERBOSE kernel option. .It Va firewall_flags .Pq Vt str Flags passed to .Xr ipfw 8 if .Va firewall_type specifies a filename. .It Va natd_program .Pq Vt str Path to .Xr natd 8 . .It Va natd_enable .Pq Vt bool Set to .Dq Li YES to enable .Xr natd 8 . .Va firewall_enable must also be set to .Dq Li YES , and .Xr divert 4 sockets must be enabled in the kernel. .It Va natd_interface .Pq Vt str This is the name of the public interface on which .Xr natd 8 should run. The interface may be given as an interface name or as an IP address. .It Va natd_flags .Pq Vt str Additional .Xr natd 8 flags should be placed here. The .Fl n or .Fl a flag is automatically added with the above .Va natd_interface as an argument. .\" ----- ipfilter_enable setting -------------------------------- .It Va ipfilter_enable .Pq Vt bool Set to .Dq Li NO by default. Setting this to .Dq Li YES enables .Xr ipf 8 packet filtering. .Pp Typical usage will require putting .Bd -literal ipfilter_enable="YES" ipnat_enable="YES" ipmon_enable="YES" ipfs_enable="YES" .Ed .Pp into .Pa /etc/rc.conf and editing .Pa /etc/ipf.rules and .Pa /etc/ipnat.rules appropriately. .Pp Note that .Va ipfilter_enable and .Va ipnat_enable can be enabled independently. .Va ipmon_enable and .Va ipfs_enable both require at least one of .Va ipfilter_enable and .Va ipnat_enable to be enabled. .Pp Having .Bd -literal options IPFILTER options IPFILTER_LOG options IPFILTER_DEFAULT_BLOCK .Ed .Pp in the kernel configuration file is a good idea, too. .\" ----- ipfilter_program setting ------------------------------ .It Va ipfilter_program .Pq Vt str Path to .Xr ipf 8 (default .Pa /sbin/ipf ) . .\" ----- ipfilter_rules setting -------------------------------- .It Va ipfilter_rules .Pq Vt str Set to .Pa /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 .Xr ipf 8 command to execute. .\" ----- ipfilter_flags setting -------------------------------- .It Va ipfilter_flags .Pq Vt str Empty by default. This variable contains flags passed to the .Xr ipf 8 program. .\" ----- ipnat_enable setting ---------------------------------- .It Va ipnat_enable .Pq Vt bool Set to .Dq Li NO by default. Set it to .Dq Li YES to enable .Xr ipnat 1 network address translation. See .Va ipfilter_enable for a detailed discussion. .\" ----- ipnat_program setting --------------------------------- .It Va ipnat_program .Pq Vt str Path to .Xr ipnat 1 (default .Pa /sbin/ipnat ) . .\" ----- ipnat_rules setting ----------------------------------- .It Va ipnat_rules .Pq Vt str Set to .Pa /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 .Xr ipnat 1 command to execute. .\" ----- ipnat_flags setting ----------------------------------- .It Va ipnat_flags .Pq Vt str Empty by default. This variable contains flags passed to the .Xr ipnat 1 program. .\" ----- ipmon_enable setting ---------------------------------- .It Va ipmon_enable .Pq Vt bool Set to .Dq Li NO by default. Set it to .Dq Li YES to enable .Xr ipmon 8 monitoring (logging .Xr ipf 8 and .Xr ipnat 1 events). Setting this variable needs setting .Va ipfilter_enable or .Va ipnat_enable too. See .Va ipfilter_enable for a detailed discussion. .\" ----- ipmon_program setting --------------------------------- .It Va ipmon_program .Pq Vt str Path to .Xr ipmon 8 (default .Pa /sbin/ipmon ) . .\" ----- ipmon_flags setting ----------------------------------- .It Va ipmon_flags .Pq Vt str Set to .Dq Li -Ds by default. This variable contains flags passed to the .Xr ipmon 8 program. Another typical example would be .Dq Fl D Pa /var/log/ipflog to have .Xr ipmon 8 log directly to a file bypassing .Xr syslogd 8 . Make sure to adjust .Pa /etc/newsyslog.conf in such case like this: .Bd -literal /var/log/ipflog 640 10 100 * Z /var/run/ipmon.pid .Ed .\" ----- ipfs_enable setting ----------------------------------- .It Va ipfs_enable .Pq Vt bool Set to .Dq Li NO by default. Set it to .Dq Li YES to enable .Xr ipfs 8 saving the filter and NAT state tables during shutdown and reloading them during startup again. Setting this variable needs setting .Va ipfilter_enable or .Va ipnat_enable to .Dq Li YES too. See .Va ipfilter_enable for a detailed discussion. Note that if .Va kern_securelevel is set to 3, .Va ipfs_enable cannot be used because the raised securelevel will prevent .Xr ipfs 8 from saving the state tables at shutdown time. .\" ----- ipfs_program setting ---------------------------------- .It Va ipfs_program .Pq Vt str Path to .Xr ipfs 8 (default .Pa /sbin/ipfs ) . .\" ----- ipfs_flags setting ------------------------------------ .It Va ipfs_flags .Pq Vt str Empty by default. This variable contains flags passed to the .Xr ipfs 8 program. .\" ----- end of added ipf hook --------------------------------- .It Va tcp_extensions .Pq Vt bool Set to .Dq Li YES by default. Setting this to .Dq Li NO disables certain TCP options as described by .Rs .%T "RFC 1323" .Re Setting this to .Dq Li 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. .It Va log_in_vain .Pq Vt int Set to 0 by default. The .Xr sysctl 8 variables, .Va net.inet.tcp.log_in_vain and .Va net.inet.udp.log_in_vain , as described in .Xr tcp 4 and .Xr udp 4 , are set to the given value. .It Va tcp_keepalive .Pq Vt bool Set to .Dq Li YES by default. Setting to .Dq Li NO will disable probing idle TCP connections to verify that the peer is still up and reachable. .It Va tcp_drop_synfin .Pq Vt bool Set to .Dq Li NO by default. Setting to .Dq Li 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 .Dv TCP_DROP_SYNFIN option. .It Va icmp_drop_redirect .Pq Vt bool Set to .Dq Li NO by default. Setting to .Dq Li YES will cause the kernel to ignore ICMP REDIRECT packets. .It Va icmp_log_redirect .Pq Vt bool Set to .Dq Li NO by default. Setting to .Dq Li 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. .It Va network_interfaces .Pq Vt 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 .Pq Li lo0 and a NIC using the .Xr ed 4 driver, this could be set to .Dq Li "lo0 ed0" . An .Va ifconfig_ Ns Aq Ar interface variable is also assumed to exist for each value of .Ar 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 .Li ed0 , it might look something like this: .Bd -literal ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff" ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff" .Ed .Pp And so on. For each .Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n entry that is found, its contents are passed to .Xr ifconfig 8 . Execution stops at the first unsuccessful access, so if something like this is present: .Bd -literal ifconfig_ed0_alias0="inet 127.0.0.251 netmask 0xffffffff" ifconfig_ed0_alias1="inet 127.0.0.252 netmask 0xffffffff" ifconfig_ed0_alias2="inet 127.0.0.253 netmask 0xffffffff" ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff" .Ed .Pp Then note that alias4 would .Em not be added since the search would stop with the missing alias3 entry. .Pp It is possible to bring up an interface with DHCP by setting the .Va ifconfig_ Ns Aq Ar interface variable to .Dq Li DHCP . For instance, to initialize the .Li ed0 device via DHCP, it is possible to use something like: .Bd -literal ifconfig_ed0="DHCP" .Ed .It Va cloned_interfaces .Pq Vt str Set to the list of clonable network interfaces to create on this host. Entries in .Va cloned_interfaces are automatically appended to .Va network_interfaces for configuration. .It Va gif_interfaces .Pq Vt str Set to the list of .Xr gif 4 tunnel interfaces to configure on this host. A .Va gifconfig_ Ns Aq Ar interface variable is assumed to exist for each value of .Ar interface . The value of this variable is used to configure the link layer of the tunnel according to the syntax of the .Cm tunnel option to .Xr ifconfig 8 . Additionally, this option ensures that each listed interface is created via the .Cm create option to .Xr ifconfig 8 before attempting to configure it. .It Va ppp_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr ppp 8 daemon. .It Va ppp_mode .Pq Vt str Mode in which to run the .Xr ppp 8 daemon. Accepted modes are .Dq Li auto , .Dq Li ddial , .Dq Li direct and .Dq Li dedicated . See the manual for a full description. .It Va ppp_nat .Pq Vt bool If set to .Dq Li YES , enables network address translation. Used in conjunction with .Va gateway_enable allows hosts on private network addresses access to the Internet using this host as a network address translating router. .It Va ppp_profile .Pq Vt str The name of the profile to use from .Pa /etc/ppp/ppp.conf . .It Va ppp_user .Pq Vt str The name of the user under which .Xr ppp 8 should be started. By default, .Xr ppp 8 is started as .Dq Li root . .It Va rc_conf_files .Pq Vt str This option is used to specify a list of files that will override the settings in .Pa /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 .Pa /etc/rc.conf and .Pa /etc/rc.conf.local .It Va fsck_y_enable .Pq Vt bool If set to .Dq Li YES , .Xr fsck 8 will be run with the .Fl y flag if the initial preen of the file systems fails. .It Va background_fsck .Pq Vt bool If set to .Dq Li YES , the system will attempt to run .Xr fsck 8 in the background where possible. .It Va background_fsck_delay .Pq Vt int The amount of time in seconds to sleep before starting a background .Xr 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 .Xr fsck 8 . .It Va extra_netfs_types .Pq Vt str If set to something other than .Dq Li NO (the default), this variable extends the list of file system types for which automatic mounting at startup by .Xr 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 .Xr mount 8 and a human-readable, one-word description, joined with a colon .Pq Ql \&: . Extending the default list in this way is only necessary when third party file system types are used. .It Va syslogd_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr syslogd 8 daemon. .It Va syslogd_program .Pq Vt str Path to .Xr syslogd 8 (default .Pa /usr/sbin/syslogd ) . .It Va syslogd_flags .Pq Vt str If .Va syslogd_enable is set to .Dq Li YES , these are the flags to pass to .Xr syslogd 8 . .It Va inetd_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr inetd 8 daemon. .It Va inetd_program .Pq Vt str Path to .Xr inetd 8 (default .Pa /usr/sbin/inetd ) . .It Va inetd_flags .Pq Vt str If .Va inetd_enable is set to .Dq Li YES , these are the flags to pass to .Xr inetd 8 . .It Va named_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr named 8 daemon. .It Va named_program .Pq Vt str Path to .Xr named 8 (default .Pa /usr/sbin/named ) . .It Va named_flags .Pq Vt str If .Va named_enable is set to .Dq Li YES , these are the flags to pass to .Xr named 8 . .It Va kerberos4_server_enable .Pq Vt bool Set to .Dq Li YES to start a Kerberos IV authentication server at boot time. .It Va kadmind4_server_enable .Pq Vt bool Set to .Dq Li YES to start .Xr kadmind 8 , the Kerberos IV Administration Daemon; set to .Dq Li NO on a slave server. .It Va kerberos_stash .Pq Vt str If .Dq Li YES , instruct the Kerberos servers to use the stashed master key instead of prompting for it (only if .Va kerberos_server_enable is set to .Dq Li YES , and is used for both .Xr kerberos 1 and .Xr kadmind 8 ) . .It Va kerberos5_server_enable .Pq Vt bool Set to .Dq Li YES to start a Kerberos 5 authentication server at boot time. .It Va kadmind5_server_enable .Pq Vt bool Set to .Dq Li YES to start .Xr k5admind 8 , the Kerberos 5 Administration Daemon; set to .Dq Li NO on a slave server. .It Va rwhod_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr rwhod 8 daemon at boot time. .It Va rwhod_flags .Pq Vt str If .Va rwhod_enable is set to .Dq Li YES , these are the flags to pass to it. .It Va amd_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr amd 8 daemon at boot time. .It Va amd_flags .Pq Vt str If .Va amd_enable is set to .Dq Li YES , these are the flags to pass to it. See the .Xr amd 8 manpage for more information. .It Va amd_map_program .Pq Vt str If set, the specified program is run to get the list of .Xr amd 8 maps. For example, if the .Xr amd 8 maps are stored in NIS, one can set this to run .Xr ypcat 1 to get a list of .Xr amd 8 maps from the .Pa amd.master NIS map. .It Va update_motd .Pq Vt bool If set to .Dq Li YES , .Pa /etc/motd will be updated at boot time to reflect the kernel release being run. If set to .Dq Li NO , .Pa /etc/motd will not be updated. .It Va nfs_client_enable .Pq Vt bool If set to .Dq Li YES , run the NFS client daemons at boot time. .It Va nfs_access_cache .Pq Vt int If .Va nfs_client_enable is set to .Dq Li YES , this can be set to .Dq Li 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 traffic for many NFS operations. .It Va nfs_server_enable .Pq Vt bool If set to .Dq Li YES , run the NFS server daemons at boot time. .It Va nfs_server_flags .Pq Vt str If .Va nfs_server_enable is set to .Dq Li YES , these are the flags to pass to the .Xr nfsd 8 daemon. .It Va mountd_enable .Pq Vt bool If set to .Dq Li YES , and no .Va nfs_server_enable is set, start .Xr mountd 8 , but not .Xr nfsd 8 daemon. It is commonly needed to run CFS without real NFS used. .It Va weak_mountd_authentication .Pq Vt bool If set to .Dq Li YES , allow services like PCNFSD to make non-privileged mount requests. .It Va nfs_privport .Pq Vt bool If set to .Dq Li YES , provide NFS services only on a secure port. .It Va nfs_bufpackets .Pq Vt int If set to a number, indicates the number of packets worth of socket buffer space to reserve on an NFS client. If set to .Dq Li DEFAULT , the kernel default is used (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. .It Va rpc_lockd_enable .Pq Vt bool If set to .Dq Li YES and also an NFS server, run .Xr rpc.lockd 8 at boot time. .It Va rpc_statd_enable .Pq Vt bool If set to .Dq Li YES and also an NFS server, run .Xr rpc.statd 8 at boot time. .It Va rpcbind_program .Pq Vt str Path to .Xr rpcbind 8 (default .Pa /usr/sbin/rpcbind ) . .It Va rpcbind_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr rpcbind 8 service at boot time. .It Va rpcbind_flags .Pq Vt str If .Va rpcbind_enable is set to .Dq Li YES , these are the flags to pass to the .Xr rpcbind 8 daemon. .It Va xtend_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr xtend 8 daemon at boot time. .It Va xtend_flags .Pq Vt str If .Va xtend_enable is set to .Dq Li YES , these are the flags to pass to the .Xr xtend 8 daemon. .It Va pppoed_enable .Pq Vt bool If set to .Dq Li YES , run the .Xr pppoed 8 daemon at boot time to provide PPP over Ethernet services. .It Va pppoed_ Ns Ar provider .Pq Vt str .Xr pppoed 8 listens to requests to this .Ar provider and ultimately runs .Xr ppp 8 with a .Ar system argument of the same name. .It Va pppoed_flags .Pq Vt str Additional flags to pass to .Xr pppoed 8 . .It Va pppoed_interface .Pq Vt str The network interface to run .Xr pppoed 8 on. This is mandatory when .Va pppoed_enable is set to .Dq Li YES . .It Va timed_enable .Pq Vt boot If set to .Dq Li YES , run the .Xr timed 8 service at boot time. This command is intended for networks of machines where a consistent .Dq "network time" for all hosts must be established. This is often useful in large NFS environments where time stamps on files are expected to be consistent network-wide. .It Va timed_flags .Pq Vt str If .Va timed_enable is set to .Dq Li YES , these are the flags to pass to the .Xr timed 8 service. .It Va ntpdate_enable .Pq Vt bool If set to .Dq Li YES , run .Xr ntpdate 8 at system startup.
