28.Dt RC.CONF 5
29.Os
30.Sh NAME
31.Nm rc.conf
32.Nd system configuration information
33.Sh DESCRIPTION
34The file
35.Nm
36contains descriptive information about the local host name, configuration
37details for any potential network interfaces and which services should be
38started up at system initial boot time.
39In new installations, the
40.Nm
41file is generally initialized by the system installation utility.
42.Pp
43The purpose of
44.Nm
45is not to run commands or perform system startup actions
46directly.
47Instead, it is included by the
48various generic startup scripts in
49.Pa /etc
50which conditionalize their
51internal actions according to the settings found there.
52.Pp
53The
54.Pa /etc/rc.conf
55file is included from the file
56.Pa /etc/defaults/rc.conf ,
57which specifies the default settings for all the available options.
58Options need only be specified in
59.Pa /etc/rc.conf
60when the system administrator wishes to override these defaults.
61The file
62.Pa /etc/rc.conf.local
63is used to override settings in
64.Pa /etc/rc.conf
65for historical reasons.
66.Pp
67In addition to
68.Pa /etc/rc.conf.local
69you can also place smaller configuration files for each
70.Xr rc 8
71script in the
72.Pa /etc/rc.conf.d
73directory or
74.Ao Ar dir Ac Ns Pa /rc.conf.d
75directories specified in
76.Va local_startup ,
77which will be included by the
78.Va load_rc_config
79function.
80For jail configurations you could use the file
81.Pa /etc/rc.conf.d/jail
82to store jail specific configuration options.
83If
84.Va local_startup
85contains
86.Pa /usr/local/etc/rc.d
87and
88.Pa /opt/conf ,
89.Pa /usr/local/rc.conf.d/jail
90and
91.Pa /opt/conf/rc.conf.d/jail
92will be loaded.
93If
94.Ao Ar dir Ac Ns Pa /rc.conf.d/ Ns Ao Ar name Ac
95is a directory,
96all of files in the directory will be loaded.
97Also see the
98.Va rc_conf_files
99variable below.
100.Pp
101Options are set with
102.Dq Ar name Ns Li = Ns Ar value
103assignments that use
104.Xr sh 1
105syntax.
106The following list provides a name and short description for each
107variable that can be set in the
108.Nm
109file:
110.Bl -tag -width indent-two
111.It Va rc_debug
112.Pq Vt bool
113If set to
114.Dq Li YES ,
115enable output of debug messages from rc scripts.
116This variable can be helpful in diagnosing mistakes when
117editing or integrating new scripts.
118Beware that this produces copious output to the terminal and
119.Xr syslog 3 .
120.It Va rc_info
121.Pq Vt bool
122If set to
123.Dq Li NO ,
124disable informational messages from the rc scripts.
125Informational messages are displayed when
126a condition that is not serious enough to warrant a warning or
127an error occurs.
128.It Va rc_startmsgs
129.Pq Vt bool
130If set to
131.Dq Li YES ,
132show
133.Dq Starting foo:
134when faststart is used (e.g., at boot time).
135.It Va early_late_divider
136.Pq Vt str
137The name of the script that should be used as the
138delimiter between the
139.Dq early
140and
141.Dq late
142stages of the boot process.
143The early stage should contain all the services needed to
144get the disks (local or remote) mounted so that the late
145stage can include scripts contained in the directories
146listed in the
147.Va local_startup
148variable (see below).
149Thus, the two likely candidates for this value are
150.Pa mountcritlocal
151for the typical system, and
152.Pa mountcritremote
153if the system needs remote file
154systems mounted to get access to the
155.Va local_startup
156directories; for example when
157.Pa /usr/local
158is NFS mounted.
159For
160.Pa rc.conf
161within a
162.Xr jail 8
163.Pa NETWORKING
164is likely to be an appropriate value.
165Extreme care should be taken when changing this value,
166and before changing it one should ensure that there are
167adequate provisions to recover from a failed boot
168(such as physical contact with the machine,
169or reliable remote console access).
170.It Va always_force_depends
171.Pq Vt bool
172Various
173.Pa rc.d
174scripts use the force_depend function to check whether required
175services are already running, and to start them if necessary.
176By default during boot time this check is bypassed if the
177required service is enabled in
178.Pa /etc/rc.conf[.local] .
179Setting this option will bypass that check at boot time and
180always test whether or not the service is actually running.
181Enabling this option is likely to increase your boot time if
182services are enabled that utilize the force_depend check.
183.It Ao Ar name Ac Ns Va _chroot
184.Pq Vt str
185.Xr chroot
186to this directory before running the service.
187.It Ao Ar name Ac Ns Va _user
188.Pq Vt str
189Run the service under this user account.
190.It Ao Ar name Ac Ns Va _group
191.Pq Vt str
192Run the chrooted service under this system group.
193Unlike the _user
194setting, this setting has no effect if the service is not chrooted.
195.It Ao Ar name Ac Ns Va _fib
196.Pq Vt int
197The
198.Xr setfib 1
199value to run the service under.
200.It Ao Ar name Ac Ns Va _nice
201.Pq Vt int
202The
203.Xr nice 1
204value to run the service under.
205.It Va apm_enable
206.Pq Vt bool
207If set to
208.Dq Li YES ,
209enable support for Automatic Power Management with
210the
211.Xr apm 8
212command.
213.It Va apmd_enable
214.Pq Vt bool
215Run
216.Xr apmd 8
217to handle APM event from userland.
218This also enables support for APM.
219.It Va apmd_flags
220.Pq Vt str
221If
222.Va apmd_enable
223is set to
224.Dq Li YES ,
225these are the flags to pass to the
226.Xr apmd 8
227daemon.
228.It Va devd_enable
229.Pq Vt bool
230Run
231.Xr devd 8
232to handle device added, removed or unknown events from the kernel.
233.It Va ddb_enable

246.It Va kld_list
247.Pq Vt str
248A list of kernel modules to load right after the local
249disks are mounted.
250Loading modules at this point in the boot process is
251much faster than doing it via
252.Pa /boot/loader.conf
253for those modules not necessary for mounting local disk.
254.It Va kldxref_enable
255.Pq Vt bool
256Set to
257.Dq Li NO
258by default.
259Set to

270by default.
271If
272.Va kldxref_enable
273is true,
274setting to
275.Dq Li YES
276will overwrite existing
277.Pa linker.hints
278files at boot time.
279Otherwise,
280only missing
281.Pa linker.hints
282files are generated.
283.It Va kldxref_module_path
284.Pq Vt str
285Empty by default.
286A semi-colon
287.Pq Ql \&;
288delimited list of paths containing

330utility when the memory file system for
331.Pa /tmp
332is created.
333The default is
334.Dq Li "-S" ,
335which inhibits the use of softupdates on
336.Pa /tmp
337so that file system space is freed without delay
338after file truncation or deletion.
339See
340.Xr mdmfs 8
341for other options you can use in
342.Va tmpmfs_flags .
343.It Va varmfs
344Controls the creation of a

377file system.
378Always happens if set to
379.Dq Li YES
380and never happens if set to
381.Dq Li NO .
382If set to anything else, a memory file system is created if
383.Pa /var
384is not writable.
385Note that this process requires access to certain commands in
386.Pa /usr
387before
388.Pa /usr
389is mounted on normal systems.
390.It Va cleanvar_enable
391.Pq Vt bool
392Clean the
393.Pa /var
394directory.

411at system boot time.
412.It Va hostname
413.Pq Vt str
414The fully qualified domain name (FQDN) of this host on the network.
415This should almost certainly be set to something meaningful, even if
416there is no network connection.
417If
418.Xr dhclient 8
419is used to set the hostname via DHCP,
420this variable should be set to an empty string.
421If this value remains unset when the system is done booting
422your console login will display the default hostname of
423.Dq Amnesiac .
424.It Va nisdomainname
425.Pq Vt str
426The NIS domain name of this host, or
427.Dq Li NO

451.It Va background_dhclient
452.Pq Vt bool
453Set to
454.Dq Li YES
455to start the DHCP client in background.
456This can cause trouble with applications depending on
457a working network, but it will provide a faster startup
458in many cases.
459.It Va background_dhclient_ Ns Aq Ar iface
460When specified, this variable overrides the
461.Va background_dhclient
462variable for interface

1168An

1172When an interface name contains any of the characters
1173.Dq Li .-/+
1174they are translated to

1176before lookup.
1177The variable can contain arguments to

1179as well as special case-insensitive keywords described below.
1180Such keywords are removed before passing the value to
1181.Xr ifconfig 8
1182while the order of the other arguments is preserved.
1183.Pp
1184It is possible to add IP alias entries using
1185.Xr ifconfig 8
1186syntax with the address family keyword such as
1187.Li inet .
1188Assuming that the interface in question was
1189.Li ed0 ,

1201.Li inet 192.0.2.5-23/24
1202or
1203.Li inet6 2001:db8:1-f::1/64 .
1204This notation allows address and prefix length part only,
1205not the other address modifiers.
1206Note that the maximum number of the generated addresses from a range
1207specification is limited to an integer value specified in
1208.Va netif_ipexpand_max
1209in
1210.Nm
1211because a small typo can unexpectedly generate a large number of addresses.
1212The default value is
1213.Li 2048 .
1214It can be increased by adding the following line into
1215.Nm :
1216.Bd -literal
1217netif_ipexpand_max="4096"
1218.Ed
1219.Pp
1220In the case of
1221.Li 192.0.2.5-23/24 ,
1222the address 192.0.2.5 will be configured with the
1223netmask /24 and the addresses 192.0.2.6 to 192.0.2.23 with
1224the non-conflicting netmask /32 as explained in the
1225.Xr ifconfig 8
1226alias section.
1227Note that this special netmask handling is only for
1228.Li inet ,
1229not for the other address families such as
1230.Li inet6 .
1231.Pp
1232With the interface in question being
1233.Li ed0 ,
1234an example could look like:

1240and so on.
1241.Pp
1242Note that
1243.Va ipv4_addrs_ Ns Aq Ar interface
1244variable was supported for IPv4 CIDR address notation.
1245It is now deprecated because the functionality was integrated into
1246.Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
1247though
1248.Va ipv4_addrs_ Ns Aq Ar interface
1249is still supported for backward compatibility.
1250.Pp
1251For each
1252.Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
1253entry with an address family keyword,
1254its contents are passed to
1255.Xr ifconfig 8 .
1256Execution stops at the first unsuccessful access, so if
1257something like this is present:
1258.Bd -literal

1262ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
1263.Ed
1264.Pp
1265Then note that alias4 would
1266.Em not
1267be added since the search would
1268stop with the missing
1269.Dq Li alias3
1270entry.
1271Because of this difficult to manage behavior,
1272there is
1273.Va ifconfig_ Ns Ao Ar interface Ac Ns Va _aliases
1274variable, which has the same functionality as
1275.Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
1276and can have all of entries in a variable like the following:
1277.Bd -literal
1278ifconfig_ed0_aliases="\\

1366.Pp
1367If the

1378.Pp
1379It is possible to bring up an interface with DHCP by adding
1380.Dq Li DHCP
1381to the
1382.Va ifconfig_ Ns Aq Ar interface
1383variable.
1384For instance, to initialize the

1387it is possible to use something like:
1388.Bd -literal
1389ifconfig_ed0="DHCP"
1390.Ed
1391.Pp
1392If you want to configure your wireless interface with
1393.Xr wpa_supplicant 8
1394for use with WPA, EAP/LEAP or WEP, you need to add
1395.Dq Li WPA
1396to the
1397.Va ifconfig_ Ns Aq Ar interface
1398variable.
1399.Pp
1400On the other hand, if you want to configure your wireless interface with
1401.Xr hostapd 8 ,
1402you need to add
1403.Dq Li HOSTAP
1404to the
1405.Va ifconfig_ Ns Aq Ar interface
1406variable.
1407.Xr hostapd 8
1408will use the settings from
1409.Pa /etc/hostapd- Ns Ao Ar interface Ac Ns .conf
1410.Pp
1411Finally, you can add
1412.Xr ifconfig 8
1413options in this variable, in addition to the
1414.Pa /etc/start_if. Ns Aq Ar interface
1415file.
1416For instance, to configure an
1417.Xr ath 4
1418wireless device in station mode with an address obtained
1419via DHCP, using WPA authentication and 802.11b mode, it is
1420possible to use something like:
1421.Bd -literal
1422wlans_ath0="wlan0"
1423ifconfig_wlan0="DHCP WPA mode 11b"
1424.Ed
1425.Pp
1426In addition to the
1427.Va ifconfig_ Ns Aq Ar interface
1428form, a fallback variable
1429.Va ifconfig_DEFAULT
1430may be configured.
1431It will be used for all interfaces with no
1432.Va ifconfig_ Ns Aq Ar interface
1433variable.
1434This is intended to replace the no longer supported
1435.Va pccard_ifconfig
1436variable.
1437.Pp
1438It is also possible to rename an interface by doing:
1439.Bd -literal

1451.Pp
1452If the variable is
1453.Dq Li YES ,
1454.Dq Li inet6 accept_rtadv
1455is added to all of
1456.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6
1457and the

1459is defined as
1460.Dq Li YES .
1461.It Va ipv6_prefer
1462.Pq Vt bool
1463This variable is deprecated.
1464Use
1465.Va ip6addrctl_policy
1466instead.
1467.Pp
1468If the variable is
1469.Dq Li YES ,
1470the default address selection policy table set by
1471.Xr ip6addrctl 8
1472will be IPv6-preferred.
1473.Pp
1474If the variable is
1475.Dq Li NO ,
1476the default address selection policy table set by

1481This controls initial configuration on IPv6-capable
1482interfaces with no corresponding
1483.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6
1484variable.
1485Note that it is not always necessary to set this variable to
1486.Dq YES
1487to use IPv6 functionality on
1488.Fx .
1489In most cases, just configuring
1490.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6
1491variables works.
1492.Pp
1493If the variable is
1494.Dq Li NO ,
1495all interfaces which do not have a corresponding
1496.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6
1497variable will be marked as
1498.Dq Li IFDISABLED
1499at creation.
1500This means that all of IPv6 functionality on that interface
1501is completely disabled to enforce a security policy.
1502If the variable is set to
1503.Dq YES ,
1504the flag will be cleared on all of the interfaces.
1505.Pp
1506In most cases, just defining an
1507.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6
1508for an IPv6-capable interface should be sufficient.
1509However, if an interface is added dynamically
1510.Pq by some tunneling protocols such as PPP, for example ,
1511it is often difficult to define the variable in advance.
1512In such a case, configuring the
1513.Dq Li IFDISABLED
1514flag can be disabled by setting this variable to
1515.Dq YES .
1516.Pp
1517For more details of the
1518.Dq Li IFDISABLED
1519flag and keywords
1520.Dq Li inet6 ifdisabled ,

1528If the variable is
1529.Dq Li YES
1530privacy addresses will be generated for each IPv6
1531interface as described in RFC 4941.
1532.It Va ipv6_network_interfaces
1533.Pq Vt str
1534This is the IPv6 equivalent of
1535.Va network_interfaces .
1536Normally manual configuration of this variable is not needed.
1537.It Va ipv6_cpe_wanif
1538.Pq Vt str
1539If the variable is set to an interface name,
1540the
1541.Xr ifconfig 8
1542options
1543.Dq inet6 -no_radr accept_rtadv
1544will be added to the specified interface automatically before evaluating
1545.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6 ,
1546and two
1547.Xr sysctl 8
1548variables
1549.Va net.inet6.ip6.rfc6204w3
1550and
1551.Va net.inet6.ip6.no_radr
1552will be set to 1.
1553.Pp
1554This means the specified interface will accept ICMPv6 Router
1555Advertisement messages on that link and add the discovered
1556routers into the Default Router List.
1557While the other interfaces can still accept RA messages if the
1558.Dq inet6 accept_rtadv
1559option is specified, adding
1560routes into the Default Router List will be disabled by
1561.Dq inet6 no_radr
1562option by default.
1563See
1564.Xr ifconfig 8
1565for more details.
1566.Pp
1567Note that ICMPv6 Router Advertisement messages will be
1568accepted even when
1569.Va net.inet6.ip6.forwarding
1570is 1
1571.Pq packet forwarding is enabled
1572when
1573.Va net.inet6.ip6.rfc6204w3

1575.Pp
1576Default is
1577.Dq Li NO .
1578.It Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6
1579.Pq Vt str
1580IPv6 functionality on an interface should be configured by
1581.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6 ,
1582instead of setting ifconfig parameters in
1583.Va ifconfig_ Ns Aq Ar interface .
1584If this variable is empty, all of IPv6 configurations on the
1585specified interface by other variables such as
1586.Va ipv6_prefix_ Ns Ao Ar interface Ac
1587will be ignored.
1588.Pp
1589Aliases should be set by
1590.Va ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n
1591with
1592.Dq Li inet6
1593keyword.
1594For example:

1600Interfaces that have an
1601.Dq Li inet6 accept_rtadv
1602keyword in
1603.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6
1604setting will be automatically configured by SLAAC
1605.Pq StateLess Address AutoConfiguration
1606described in
1607.Rs
1608.%T "RFC 4862"
1609.Re
1610.Pp
1611Note that a link-local address will be automatically configured in
1612addition to the configured global-scope addresses because the IPv6
1613specifications require it on each link.
1614The address is calculated from the MAC address by using an algorithm
1615defined in
1616.Rs
1617.%T "RFC 4862"
1618.%O "Section 5.3"
1619.Re
1620.Pp
1621If only a link-local address is needed on the interface,
1622the following configuration can be used:
1623.Bd -literal
1624ifconfig_ed0_ipv6="inet6 auto_linklocal"
1625.Ed
1626.Pp
1627A link-local address can also be configured manually.
1628This is useful for the default router address of an IPv6 router
1629so that it does not change when the network interface
1630card is replaced.
1631For example:
1632.Bd -literal
1633ifconfig_ed0_ipv6="inet6 fe80::1 prefixlen 64"
1634.Ed
1635.It Va ipv6_prefix_ Ns Aq Ar interface
1636.Pq Vt str
1637If one or more prefixes are defined in
1638.Va ipv6_prefix_ Ns Aq Ar interface
1639addresses based on each prefix and the EUI-64 interface index will be
1640configured on that interface.
1641Note that this variable will be ignored when
1642.Va ifconfig_ Ns Ao Ar interface Ac Ns _ipv6
1643is empty.
1644.Pp
1645For example, the following configuration
1646.Bd -literal
1647ipv6_prefix_ed0="2001:db8:1:0 2001:db8:2:0"
1648.Ed
1649.Pp
1650is equivalent to the following:
1651.Bd -literal
1652ifconfig_ed0_alias0="inet6 2001:db8:1:: eui64 prefixlen 64"
1653ifconfig_ed0_alias1="inet6 2001:db8:1:: prefixlen 64 anycast"
1654ifconfig_ed0_alias2="inet6 2001:db8:2:: eui64 prefixlen 64"
1655ifconfig_ed0_alias3="inet6 2001:db8:2:: prefixlen 64 anycast"
1656.Ed
1657.Pp
1658These Subnet-Router anycast addresses will be added only when
1659.Va ipv6_gateway_enable

1661.It Va ipv6_default_interface
1662.Pq Vt str
1663If not set to

1665this is the default output interface for scoped addresses.
1666This works only with ipv6_gateway_enable="NO".
1667.It Va ip6addrctl_enable
1668.Pq Vt bool
1669This variable is to enable configuring default address selection policy table
1670.Pq RFC 3484 .
1671The table can be specified in another variable
1672.Va ip6addrctl_policy .
1673For
1674.Va ip6addrctl_policy
1675the following keywords can be specified:
1676.Dq Li ipv4_prefer ,
1677.Dq Li ipv6_prefer ,
1678or
1679.Dq Li AUTO .
1680.Pp
1681If
1682.Dq Li ipv4_prefer
1683or
1684.Dq Li ipv6_prefer
1685is specified,
1686.Xr ip6addrctl 8
1687installs a pre-defined policy table described in Section 2.1
1688.Pq IPv6-preferred
1689or 10.3
1690.Pq IPv4-preferred
1691of RFC 3484.
1692.Pp
1693If
1694.Dq Li AUTO
1695is specified, it attempts to read a file
1696.Pa /etc/ip6addrctl.conf
1697first.
1698If this file is found,
1699.Xr ip6addrctl 8
1700reads and installs it.
1701If not found, a policy is automatically set
1702according to
1703.Va ipv6_activate_all_interfaces
1704variable; if the variable is set to
1705.Dq Li YES
1706the IPv6-preferred one is used.
1707Otherwise IPv4-preferred.
1708.Pp
1709The default value of
1710.Va ip6addrctl_enable
1711and
1712.Va ip6addrctl_policy
1713are
1714.Dq Li YES
1715and

1992.Xr fsck 8 .
1993If set to a negative number, the background file system check will be
1994delayed indefinitely to allow the administrator to run it at a more
1995convenient time.
1996For example it may be run from
