#!/bin/sh # # This is rc.conf - a file full of useful variables that you can set # to change the default startup behavior of your system. You should # not edit this file! Put any overrides into one of the ${rc_conf_files} # instead and you will be able to update these defaults later without # spamming your local configuration information. # # The ${rc_conf_files} files should only contain values which override # values set in this file. This eases the upgrade path when defaults # are changed and new features are added. # # All arguments must be in double or single quotes. # # $FreeBSD$ ############################################################## ### Important initial Boot-time options #################### ############################################################## rc_ng="YES" # Set to NO to disable new-style rc scripts. rc_info="YES" # Enables display of informational messages at boot. rcshutdown_timeout="30" # Seconds to wait before terminating rc.shutdown swapfile="NO" # Set to name of swapfile if aux swapfile desired. apm_enable="NO" # Set to YES to enable APM BIOS functions (or NO). apmd_enable="NO" # Run apmd to handle APM event from userland. apmd_flags="" # Flags to apmd (if enabled). devd_enable="NO" # Run devd, to trigger programs on device tree changes. pccard_enable="NO" # Set to YES if you want to configure PCCARD devices. pccard_mem="DEFAULT" # If pccard_enable=YES, this is card memory address. pccard_beep="2" # pccard beep type. pccard_ifconfig="NO" # Specialized pccard ethernet configuration (or NO). pccardd_flags="" # Additional flags for pccardd. pccard_conf="/etc/defaults/pccard.conf" # pccardd(8) config file pccard_ether_delay="5" # Delay before trying to start dhclient in pccard_ether removable_interfaces="" # Removable network interfaces for /etc/pccard_ether. local_startup="/usr/local/etc/rc.d /usr/X11R6/etc/rc.d" # startup script dirs. script_name_sep=" " # Change if your startup scripts' names contain spaces rc_conf_files="/etc/rc.conf /etc/rc.conf.local" fsck_y_enable="NO" # Set to YES to do fsck -y if the initial preen fails. background_fsck="YES" # Attempt to run fsck in the background where possible. extra_netfs_types="NO" # List of network extra filesystem types for delayed # mount at startup (or NO). ############################################################## ### Network configuration sub-section ###################### ############################################################## ### Basic network and firewall/security options: ### hostname="" # Set this! nisdomainname="NO" # Set to NIS domain if using NIS (or NO). dhcp_program="/sbin/dhclient" # Path to dhcp client program. dhcp_flags="" # Additional flags to pass to dhcp client. firewall_enable="NO" # Set to YES to enable firewall functionality firewall_script="/etc/rc.firewall" # Which script to run to set up the firewall firewall_type="UNKNOWN" # Firewall type (see /etc/rc.firewall) firewall_quiet="NO" # Set to YES to suppress rule display firewall_logging="NO" # Set to YES to enable events logging firewall_flags="" # Flags passed to ipfw when type is a file ip_portrange_first="NO" # Set first dynamically allocated port ip_portrange_last="NO" # Set last dynamically allocated port ipsec_enable="NO" # Set to YES to run setkey on ipsec_file ipsec_file="/etc/ipsec.conf" # Name of config file for setkey natd_program="/sbin/natd" # path to natd, if you want a different one. natd_enable="NO" # Enable natd (if firewall_enable == YES). natd_interface="" # Public interface or IPaddress to use. natd_flags="" # Additional flags for natd. ipfilter_enable="NO" # Set to YES to enable ipfilter functionality ipfilter_program="/sbin/ipf" # where the ipfilter program lives ipfilter_rules="/etc/ipf.rules" # rules definition file for ipfilter, see # /usr/src/contrib/ipfilter/rules for examples ipfilter_flags="" # additional flags for ipfilter ipnat_enable="NO" # Set to YES to enable ipnat functionality ipnat_program="/sbin/ipnat" # where the ipnat program lives ipnat_rules="/etc/ipnat.rules" # rules definition file for ipnat ipnat_flags="" # additional flags for ipnat ipmon_enable="NO" # Set to YES for ipmon; needs ipfilter or ipnat ipmon_program="/sbin/ipmon" # where the ipfilter monitor program lives ipmon_flags="-Ds" # typically "-Ds" or "-D /var/log/ipflog" ipfs_enable="NO" # Set to YES to enable saving and restoring # of state tables at shutdown and boot ipfs_program="/sbin/ipfs" # where the ipfs program lives ipfs_flags="" # additional flags for ipfs tcp_extensions="YES" # Set to NO to turn off RFC1323 extensions. log_in_vain="0" # >=1 to log connects to ports w/o listeners. tcp_keepalive="YES" # Enable stale TCP connection timeout (or NO). # For the following option you need to have TCP_DROP_SYNFIN set in your # kernel.
