NAME
smbcontrol - send messages to smbd, nmbd or winbindd
processes
SYNOPSIS
smbcontrol [-i] [-s]
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
-h|--help
Print a summary of command line options.
-s <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.
-i Run interactively. Individual commands of the form desti-
nation message-type parameters can be entered on STDIN.
An empty command line or a "q" will quit the program.
destination
One of nmbd, smbd or a process ID.
The smbd destination causes the message to "broadcast" to
all smbd daemons.
The nmbd destination causes the message to be sent to the
nmbd daemon specified in the nmbd.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.
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 parame-
ter. 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 pro-
file stats. This can be sent to any smbd or nmbd destina-
tions.
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 destina-
tions.
printnotify
Order smbd to send a printer notify message to any Win-
dows 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 occured. It doesn't actually cause the event to
happen.
This message can only be sent to smbd.
samsync
Order smbd to synchronise sam database from PDC (being
BDC). Can only be sent to smbd.
Note Not working at the moment
samrepl
Send sam replication message, with specified serial. Can
only be sent to smbd. Should not be used manually.
dmalloc-mark
Set a mark for dmalloc. Can be sent to both smbd and
nmbd. Only available if samba is built with dmalloc sup-
port.
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

SMBCONTROL(1) USER COMMANDS SMBCONTROL(1)

update their local version of the driver. Can only be

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 Doc-
Book XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
