smbcontrol - send messages to smbd, nmbd or winbindd processes
smbcontrol [-i] [-s]
smbcontrol [destination] [message-type] [parameter]
This tool is part of the samba(7) suite.
smbcontrol is a very small program, which sends messages to a smbd(1M), a nmbd(1M), or a
winbindd(1M) daemon running on the system.
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.
Run interactively. Individual commands of the form destination message-type parameters
can be entered on STDIN. An empty command line or a "q" will quit the program.
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
If a single process ID is given, the message is sent to only that process.
Type of message to send. See the section MESSAGE-TYPES for details.
any parameters required for the message-type
Available message types are:
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.
Set debug level to the value specified by the parameter. This can be sent to any of
This message causes the nmbd daemon to force a new browse master election.
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.
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
Request debuglevel of a certain daemon and write it to stdout. This can be sent to any
of the destinations.
Request profilelevel of a certain daemon and write it to stdout. This can be sent to
any smbd or nmbd destinations.
Order smbd to send a printer notify message to any Windows NT clients connected to a
printer. This message-type takes the following arguments:
Send a queue pause change notify message to the printer specified.
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.
Order smbd to synchronise sam database from PDC (being BDC). Can only be sent to smbd.
Not working at the moment
Send sam replication message, with specified serial. Can only be sent to smbd. Should
not be used manually.
Set a mark for dmalloc. Can be sent to both smbd and nmbd. Only available if samba is
built with dmalloc support.
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.
Shut down specified daemon. Can be sent to both smbd and nmbd.
Print a human-readable description of all talloc(pool) memory usage by the specified
daemon/process. Available for both smbd and nmbd.
Force clients of printers using specified driver to update their local version of the
driver. Can only be sent to smbd.
Force daemon to reload smb.conf configuration file. Can be sent to smbd, nmbd, or

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.

Samba(7) delivers the set of four SMF(5) services as can be seen from the following

where the services are:
runs the smbd daemon managing the CIFS sessions
runs the nmbd daemon enabling the browsing (WINS)
runs the winbindd daemon making the domain idmap
Samba Web Administration Tool is a service providing access to browser-based Samba
administration interface and on-line documentation. The service runs on software
loopback network interface on port 901/tcp, i.e. opening "http://localhost:901/" in
browser will access the SWAT service on local machine.
Please note: SWAT uses HTTP Basic Authentication scheme where user name and passwords are
sent over the network in clear text. In the SWAT case the user name is root. Transferring
such sensitive data is advisable only on the software loopback network interface or over
