|
|
.Nd local configuration information.
|
|
.Sh DESCRIPTION
|
|
The file
|
|
.Nm 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
|
|
.Nm rc.conf
|
|
file is generally initialized by the system installation utility:
|
|
.Pa /stand/sysinstall .
|
|
.Pp
|
|
It is the duty of the system administrator to properly maintain this file
|
|
as changes occur on the local host.

.Sh DESCRIPTION
|
|
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 following list provides a name and short description for each
|
|
variable you can set in the
|
|
.Nm
|
|
file:
|
|
.Bl -tag -width Ar
|
|
.It Ar swapfile
|
|
(str) If set to
|
|
.Ar NO
|
|
then no swapfile is installed, otherwise the value is used as the full
|
|
pathname to a file to use for additional swap space.
|
|
.It Ar apm_enable
|
|
(bool) If set to
|
|
.Ar YES ,
|
|
enable support for Automatic Power Management with
|
|
the
|
|
.Xr apm 8
|
|
command.
|
|
.It Ar pccard_enable
|
|
(bool) If set to
|
|
.Ar YES ,
|
|
enable PCCARD support at boot time.
|
|
.It Ar pccard_mem
|
|
(str) Set to PCCARD controller memory address or
|
|
.Ar DEFAULT
|
|
for the default value.
|
|
.It Ar pccard_ifconfig
|
|
(str) List of ethernet devices (e.g.
|
|
.Ar "ed0 ed1 ep0 ..." )
|
|
which should be dynamically ifconfig'd on insertion or boot.
|
|
.It Ar local_startup
|
|
(str) List of directories to search for startup script files.
|
|
.It Ar local_periodic
|
|
(str) List of directories to search for periodic scripts (3.0 only).
|
|
.It Ar hostname
|
|
(str) The Fully Qualified Domain Name of your host on the network.
|
|
This should almost certainly be set to something meaningful, even if
|
|
you've no network connected.
|
|
.It Ar nisdomainname
|
|
(str) The NIS domainname of your host, or
|
|
.Ar NO
|
|
if you're not running NIS.
|
|
.It Ar firewall_enable
|
|
(bool) Set to
|
|
.Ar NO
|
|
if you don't want have firewall rules loaded at startup, or
|
|
.Ar YES
|
|
if you do.
|
|
If set to
|
|
.Ar YES ,
|
|
and the kernel was not built with IPFIREWALL, the ipfw
|
|
kernel module will be loaded.
|
|
.It Ar firewall_type
|
|
(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 ``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.
|
|
.It Ar firewall_quiet
|
|
(bool) Set to
|
|
.Ar YES
|
|
to disable the display of ipfw rules on the console during boot.
|
|
.It Ar tcp_extensions
|
|
(bool) Set to
|
|
.Ar YES
|
|
by default, this enables certain TCP options as described by
|
|
Internet RFCs 1323 and 1644. If you have problems with connections
|
|
randomly hanging or other weird behavior of such nature, you might
|
|
try setting this to
|
|
.Ar NO
|
|
and seeing if that helps. Some hardware/software out there is known
|
|
to be broken with respect to these options.
|
|
.It Ar network_interfaces
|
|
(str) Set to the list of network interfaces to configure on this host.
|
|
For example, if you had a loopback device (standard) and an SMC Elite
|
|
Ultra NIC, you might have this set to
|
|
.Qq Ar "lo0 ed0"
|
|
for the two interfaces. An
|
|
.No ifconfig_ Ns Em interface
|
|
variable is also assumed to exist for each value of
|
|
.Em interface .
|
|
It is also possible to add IP alias entries here in cases where you
|
|
want a single interface to have multiple IP addresses registered against
|
|
it.
|
|
Assuming that the interface in question was 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
|
|
And so on. For each ifconfig_<interface>_alias<n> entry that is
|
|
found, its contents are passed to
|
|
.Xr ifconfig 8 .
|
|
Execution stops at the first unsuccessful access, so if you
|
|
had something like:
|
|
.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
|
|
Then note that alias4 would \fBnot\fR be added since the search would
|
|
stop with the missing alias3 entry.
|
|
.It Ar syslogd_enable
|
|
(bool) If set to
|
|
.Ar YES ,
|
|

|

|
|
