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, 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 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 variable below. The following list provides a name and short description for each vari- able 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. 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 automati- cally 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_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) dae- mon (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. 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 (FQDN) of this host on the network. This should almost certainly be set to some- thing meaningful, even if there is no network connection. If dhclient(8) is used to set the hostname via DHCP, this vari- able should be set to an empty string. ipv6_enable (bool) Enable support for IPv6 networking. Note that this requires 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 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 work- ing 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 ker- nel 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 fire- wall 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. natd_interface (str) This is the name of the public interface on which natd(8) should run. The interface may be given as an inter- face 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 con- tains 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 con- tains 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(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 trans- lation 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 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 exam- ple 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 shut- down 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. tcp_extensions (bool) Set to ``YES'' by default. Setting this to ``NO'' disables certain TCP options as described by RFC 1323. Set- ting this to ``NO'' might help remedy such problems with con- nections 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. 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 entries here in cases where multiple IP addresses registered against a single interface are desired. 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>_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 something like: ifconfig_ed0="DHCP" 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>_alias<n>. 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 inter- face 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 cre- ate on this host. Entries in cloned_interfaces are automati- cally appended to network_interfaces for configuration. gif_interfaces (str) Set to the list of gif(4) tunnel interfaces to config- ure 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 tun- nel 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_nat (bool) If set to ``YES'', enables network address transla- tion. 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 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''. 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 white- space-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. 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 (bool) If set to ``YES'', run the inetd(8) daemon. inetd_program (str) Path to inetd(8) (default /usr/sbin/inetd). inetd_flags (str) If inetd_enable is set to ``YES'', these are the flags to pass to inetd(8). named_rcng (bool) If set to ``YES'' use new functionality provided in the /etc/rc.d/named script to facilitate a chroot(8) instance of named(8). This variable is experimental. It may be removed or changed in the near future. named_enable (bool) If set to ``YES'', run the named(8) daemon. named_program (str) Path to named(8) (default /usr/sbin/named). named_flags (str) If named_enable is set to ``YES'', these are the flags to pass to named(8). named_pidfile (str) This is the default path to the named(8) daemon's PID file. Change it if you change the location in named.conf(5). named_chrootdir (str) The root directory for a name server run in a chroot(8) environment. If left empty named(8) will not be run in a chroot(8) environment. This variable has no effect if named_rcng is not enabled. This variable is experimental. It may be removed or changed in the near future. named_chroot_autoupdate (bool) Set to ``NO'' to disable automatic syncing of libraries and other system files between the root file system and the chroot(8). This variable has no effect if named_rcng is not enabled. This variable is experimental. It may be removed or changed in the near future. named_symlink_enable (bool) Set to ``NO'' to disable symlinking of named_pidfile and /var/run/ndc into the chroot(8) environment in which named(8) is running. This variable has no effect if named_rcng is not enabled. This variable is experimental. It may be removed or changed in the near future. kerberos5_server_enable (bool) Set to ``YES'' to start a Kerberos 5 authentication server at boot time. kerberos5_server (str) If kerberos5_server_enable is set to ``YES'' this is the path to Kerberos 5 Authentication Server. kadmind5_server_enable (bool) Set to ``YES'' to start kadmind(8), the Kerberos 5 Administration Daemon; set to ``NO'' on a slave server. kadmind5_server (str) If kadmind5_server_enable is set to ``YES'' this is the path to Kerberos 5 Administration Daemon. kpasswdd_server_enable (bool) Set to ``YES'' to start kpasswdd(8), the Kerberos 5 Password-Changing Daemon; set to ``NO'' on a slave server. kpasswdd_server (str) If kpasswdd_server_enable is set to ``YES'' this is the path to Kerberos 5 Password-Changing Daemon. rwhod_enable (bool) If set to ``YES'', run the rwhod(8) daemon at boot time. rwhod_flags (str) If rwhod_enable is set to ``YES'', these are the flags to pass to it. amd_enable (bool) If set to ``YES'', run the amd(8) daemon at boot time. amd_flags (str) If amd_enable is set to ``YES'', these are the flags to pass to it. See the amd(8) manpage for more information. amd_map_program (str) If set, the specified program is run to get the list of amd(8) maps. For example, if the amd(8) maps are stored in NIS, one can set this to run ypcat(1) to get a list of amd(8) maps from the amd.master NIS map. update_motd (bool) If set to ``YES'', /etc/motd will be updated at boot time to reflect the kernel release being run. If set to ``NO'', /etc/motd will not be updated. nfs_client_enable (bool) If set to ``YES'', run the NFS client daemons at boot time. nfs_access_cache (int) If nfs_client_enable is set to ``YES'', this can be set to ``0'' to disable NFS ACCESS RPC caching, or to the number of seconds for which NFS ACCESS results should be cached.

The minimum value is 2 and the maximum is 64. rpc_lockd_enable (bool) If set to ``YES'' and also an NFS server, run rpc.lockd(8) at boot time. rpc_statd_enable (bool) If set to ``YES'' and also an NFS server, run rpc.statd(8) at boot time. rpcbind_program (str) Path to rpcbind(8) (default /usr/sbin/rpcbind). rpcbind_enable (bool) If set to ``YES'', run the rpcbind(8) service at boot time. rpcbind_flags (str) If rpcbind_enable is set to ``YES'', these are the flags to pass to the rpcbind(8) daemon. keyserv_enable (bool) If set to ``YES'', run the keyserv(8) daemon on boot for running Secure RPC. keyserv_flags (str) If keyserv_enable is set to ``YES'', these are the flags to pass to keyserv(8) daemon. pppoed_enable (bool) If set to ``YES'', run the pppoed(8) daemon at boot time to provide PPP over Ethernet services. pppoed_provider (str) pppoed(8) listens to requests to this provider and ultimately runs ppp(8) with a system argument of the same name. pppoed_flags (str) Additional flags to pass to pppoed(8). pppoed_interface (str) The network interface to run pppoed(8) on. This is mandatory when pppoed_enable is set to ``YES''. timed_enable (bool) If set to ``YES'', run the timed(8) service at boot time. This command is intended for networks of machines where a consistent ``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 net- work-wide. timed_flags (str) If timed_enable is set to ``YES'', these are the flags to pass to the timed(8) service. ntpdate_enable (bool) If set to ``YES'', run ntpdate(8) at system startup. This command is intended to synchronize the system clock only once from some standard reference. An option to set this up initially (from a list of known servers) is also provided by the sysinstall(8) program when the system is first installed. ntpdate_program (str) Path to ntpdate(8) (default /usr/sbin/ntpdate). ntpdate_flags (str) If ntpdate_enable is set to ``YES'', these are the flags to pass to the ntpdate(8) command (typically a host- name). ntpd_enable (bool) If set to ``YES'', run the ntpd(8) command at boot time. ntpd_program (str) Path to ntpd(8) (default /usr/sbin/ntpd). ntpd_flags (str) If ntpd_enable is set to ``YES'', these are the flags to pass to the ntpd(8) daemon. nis_client_enable (bool) If set to ``YES'', run the ypbind(8) service at system boot time. nis_client_flags (str) If nis_client_enable is set to ``YES'', these are the flags to pass to the ypbind(8) service. nis_ypset_enable (bool) If set to ``YES'', run the ypset(8) daemon at system boot time. nis_ypset_flags (str) If nis_ypset_enable is set to ``YES'', these are the flags to pass to the ypset(8) daemon. nis_server_enable (bool) If set to ``YES'', run the ypserv(8) daemon at system boot time. nis_server_flags (str) If nis_server_enable is set to ``YES'', these are the flags to pass to the ypserv(8) daemon. nis_ypxfrd_enable (bool) If set to ``YES'', run the rpc.ypxfrd(8) daemon at system boot time. nis_ypxfrd_flags (str) If nis_ypxfrd_enable is set to ``YES'', these are the flags to pass to the rpc.ypxfrd(8) daemon. nis_yppasswdd_enable (bool) If set to ``YES'', run the rpc.yppasswdd(8) daemon at system boot time. nis_yppasswdd_flags (str) If nis_yppasswdd_enable is set to ``YES'', these are the flags to pass to the rpc.yppasswdd(8) daemon. rpc_ypupdated_enable (bool) If set to ``YES'', run the rpc.ypupdated daemon at system boot time. defaultrouter (str) If not set to ``NO'', create a default route to this host name or IP address (use an IP address if this router is also required to get to the name server!). ipv6_defaultrouter (str) The IPv6 equivalent of defaultrouter. static_routes (str) Set to the list of static routes that are to be added at system boot time. If not set to ``NO'' then for each whitespace separated element in the value, a route_<element> variable is assumed to exist whose contents will later be passed to a ``route add'' operation. ipv6_static_routes (str) The IPv6 equivalent of static_routes. If not set to ``NO'' then for each whitespace separated element in the value, a ipv6_route_<element> variable is assumed to exist whose contents will later be passed to a ``route add -inet6'' operation. natm_static_routes (str) The natmip(4) equivalent of static_routes. If not empty then for each whitespace separated element in the value, a route_<element> variable is assumed to exist whose contents will later be passed to a ``atmconfig natm add'' operation. gateway_enable (bool) If set to ``YES'', configure host to act as an IP router, e.g. to forward packets between interfaces. ipv6_gateway_enable (bool) The IPv6 equivalent of gateway_enable. router_enable (bool) If set to ``YES'', run a routing daemon of some sort, based on the settings of router and router_flags. ipv6_router_enable (bool) The IPv6 equivalent of router_enable. If set to ``YES'', run a routing daemon of some sort, based on the set- tings of ipv6_router and ipv6_router_flags. router (str) If router_enable is set to ``YES'', this is the name of the routing daemon to use. ipv6_router (str) The IPv6 equivalent of router. router_flags (str) If router_enable is set to ``YES'', these are the flags to pass to the routing daemon. ipv6_router_flags (str) The IPv6 equivalent of router_flags. mrouted_enable (bool) If set to ``YES'', run the multicast routing daemon, mrouted(8). mroute6d_enable (bool) The IPv6 equivalent of mrouted_enable.

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 detection 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 pro- tocols are for serial mice and will not work with the PS/2 and bus mice.

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.
