The rcctl utility can enable or disable a base system
service or a base system or package
daemon in
rc.conf.local(8) or display its
configuration and status. For a daemon, it can also
change the command line arguments, the user to run as, the
rc.d(8) action timeout or call its
rc.d(8) daemon control
script.
The following commands are available
(variable can be one of class,
flags, status,
timeout or user):
- [
-df] action daemon ...
- Run the rc.d(8)
daemon scripts with the action
argument, passing through the specified options, if any.
disable
service ... | daemon ...- Alias for
set
service|daemon
status off.
enable
service ... | daemon ...- Alias for
set
service|daemon
status on.
get
service | daemon
[variable]- Display the value of service or
daemon_variable. If
variable is empty, display all
service or daemon variables
and values in a format compatible with
rc.conf(8). When
daemon is set to “all”,
variable must not be set and
rcctl will display all services and daemons
variables.
getdef
service | daemon
[variable]- Like
get but returns the default values.
ls
lsarg- Display a list of services and daemons matching
lsarg, which can be one of:
all- all services and daemons
failed- enabled but stopped daemons
off- disabled services and daemons
on- enabled services and daemons
started- running daemons
stopped- stopped daemons
order
[daemon ...]- Move the specified package daemons to the beginning of
pkg_scripts. They need to be already enabled. If no
daemon is specified, display the current order.
The order command is only needed after
enabling a new daemon that needs to run before one or more already
enabled daemons. Specify the new daemon preceded by all that need to run
before it, but not the ones depending on it.
set
service | daemon variable
[arguments]- For a daemon, set the variable
daemon_variable to the
specified arguments. If
variable is already set,
daemon_variable is reset to
the optionally provided arguments or to its default
value.
The status
variable must be provided with the
on or off
arguments. It is used to enable or disable
service or daemon in
rc.conf.local(8). When a
disabled package daemon is enabled, it is appended to the end of
pkg_scripts. When a package daemon is disabled, it
is removed from pkg_scripts and its variables are
removed if any.
rcctl action returns with the exit
status of the rc.d(8)
daemon script. rcctl
get daemon |
service [status] exits with 0 if
the daemon or service is enabled and 1 if it is not.
rcctl getdef
daemon | service
[status] exits with 0 if the daemon or service is
enabled by default and 1 if it is not. rcctl
ls failed exits with 1 if an enabled daemon is not
running. Otherwise, the rcctl utility exits with 0 on
success, and >0 if an error occurs (2 indicates a non-existent
daemon | service).
Enable and set apmd(8) flags:
# rcctl set apmd status on
# rcctl set apmd flags -A
# rcctl get apmd
apmd_class=daemon
apmd_flags=-A
apmd_rtable=0
apmd_timeout=30
apmd_user=root
# echo $?
0
The recommended way to run a second copy of a given daemon for a
different purpose is to create a symbolic link to its
rc.d(8) control script:
# ln -s /etc/rc.d/snmpd /etc/rc.d/snmpd6
# rcctl set snmpd6 status on
# rcctl set snmpd6 flags -D addr=2001:db8::1234
# rcctl start snmpd6
rcctl first appeared in OpenBSD
5.7.
