NAME
smbcontrol - send messages to smbd, nmbd or winbindd processes
SYNOPSIS
smbcontrol [-s] [-t|--timeout]
smbcontrol [destination] [message-type] [parameter]
DESCRIPTION
This tool is part of the samba(7) suite.
smbcontrol is a very small program, which sends messages to a smbd(8),
a nmbd(8), or a winbindd(8) daemon running on the system.
OPTIONS
-?|--help
Print a summary of command line options.
--usage
Display brief usage message.
-s|--configfile=<configuration file>
The file specified contains the configuration details required by
the server. The information in this file includes server-specific
information such as what printcap file to use, as well as
descriptions of all the services that the server is to provide. See
smb.conf for more information. The default configuration file name
is determined at compile time.
-d|--debuglevel=level
level is an integer from 0 to 10. The default value if this
parameter is not specified is 1.
The higher this value, the more detail will be logged to the log
files about the activities of the server. At level 0, only critical
errors and serious warnings will be logged. Level 1 is a reasonable
level for day-to-day running - it generates a small amount of
information about operations carried out.
Levels above 1 will generate considerable amounts of log data, and
should only be used when investigating a problem. Levels above 3
are designed for use only by developers and generate HUGE amounts
of log data, most of which is extremely cryptic.
Note that specifying this parameter here will override the log
level parameter in the smb.conf file.
-V|--version
Prints the program version number.
-s|--configfile=<configuration file>
The file specified contains the configuration details required by
the server. The information in this file includes server-specific
information such as what printcap file to use, as well as
descriptions of all the services that the server is to provide. See
smb.conf for more information. The default configuration file name
is determined at compile time.
-l|--log-basename=logdirectory
Base directory name for log/debug files. The extension ".progname"
will be appended (e.g. log.smbclient, log.smbd, etc...). The log
file is never removed by the client.
--option=<name>=<value>
Set the smb.conf(5) option "<name>" to value "<value>" from the
command line. This overrides compiled-in defaults and options read
from the configuration file.
-t|--timeout
Set timeout to seconds.
destination
One of nmbd, smbd, winbindd or a process ID.
The all destination causes the message to "broadcast" to all
running daemons including nmbd and winbind. This is a change for
Samba 3.3, prior to this the parameter smbd used to do this.
The smbd destination causes the message to be sent to the smbd
daemon specified in the smbd.pid file.
The nmbd destination causes the message to be sent to the nmbd
daemon specified in the nmbd.pid file.
The winbindd destination causes the message to be sent to the
winbind daemon specified in the winbindd.pid file.
If a single process ID is given, the message is sent to only that
process.
message-type
Type of message to send. See the section MESSAGE-TYPES for details.
parameters
any parameters required for the message-type
MESSAGE-TYPES
Available message types are:
close-share
Order smbd to close the client connections to the named share. Note
that this doesn't affect client connections to any other shares.
This message-type takes an argument of the share name for which
client connections will be closed, or the "*" character which will
close all currently open shares. This may be useful if you made
changes to the access controls on the share. This message can only
be sent to smbd.
debug
Set debug level to the value specified by the parameter. This can
be sent to any of the destinations. If this message is sent to
either the smbd or winbindd daemons, the parent process will
rebroadcast the message to all child processes changing the debug
level in each one.
kill-client-ip
Order smbd to close the client connections from a given IP address.
This message-type takes an argument of the IP address from which
client connections will be closed. This message can only be sent to
smbd.
force-election
This message causes the nmbd daemon to force a new browse master
election.
ping
Send specified number of "ping" messages and wait for the same
number of reply "pong" messages. This can be sent to any of the
destinations.
profile
Change profile settings of a daemon, based on the parameter. The
parameter can be "on" to turn on profile stats collection, "off" to
turn off profile stats collection, "count" to enable only
collection of count stats (time stats are disabled), and "flush" to
zero the current profile stats. This can be sent to any smbd or
nmbd destinations.
debuglevel
Request debuglevel of a certain daemon and write it to stdout. This
can be sent to any of the destinations.
profilelevel
Request profilelevel of a certain daemon and write it to stdout.
This can be sent to any smbd or nmbd destinations.
printnotify
Order smbd to send a printer notify message to any Windows NT
clients connected to a printer. This message-type takes the
following arguments:
queuepause printername
Send a queue pause change notify message to the printer
specified.
queueresume printername
Send a queue resume change notify message for the printer
specified.
jobpause printername unixjobid
Send a job pause change notify message for the printer and unix
jobid specified.
jobresume printername unixjobid
Send a job resume change notify message for the printer and
unix jobid specified.
jobdelete printername unixjobid
Send a job delete change notify message for the printer and
unix jobid specified.
Note that this message only sends notification that an event has
occurred. It doesn't actually cause the event to happen.
This message can only be sent to smbd.
dmalloc-mark
Set a mark for dmalloc. Can be sent to both smbd and nmbd. Only
available if samba is built with dmalloc support.
dmalloc-log-changed
Dump the pointers that have changed since the mark set by
dmalloc-mark. Can be sent to both smbd and nmbd. Only available if
samba is built with dmalloc support.
shutdown
Shut down specified daemon. Can be sent to both smbd and nmbd.
pool-usage
Print a human-readable description of all talloc(pool) memory usage
by the specified daemon/process. Available for both smbd and nmbd.
drvupgrade
Force clients of printers using specified driver to update their
local version of the driver. Can only be sent to smbd.
reload-config
Force daemon to reload smb.conf configuration file. Can be sent to
smbd, nmbd, or winbindd.
reload-printers
Force smbd to reload printers. Can only be sent to smbd.
idmap
Notify about changes of id mapping. Can be sent to smbd or (not
implemented yet) winbindd.
flush [uid|gid]
Flush caches for sid <-> gid and/or sid <-> uid mapping.
delete <ID>
Remove a mapping from cache. The mapping is given by <ID> which
may either be a sid: S-x-..., a gid: "GID number" or a uid:
"UID number".
kill <ID>
Remove a mapping from cache. Terminate smbd if the id is
currently in use.
num-children
Query the number of smbd child processes. This message can only be
sent to smbd.

AUTHOR
The original Samba software and related utilities were created by
Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
The original Samba man pages were written by Karl Auer. The man page
sources were converted to YODL format (another excellent piece of Open
Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and
updated for the Samba 2.0 release by Jeremy Allison. The conversion to
DocBook for Samba 2.2 was done by Gerald Carter. The conversion to
DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
