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 serv-
er. 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 de-
fault configuration file name is determined at compile time.

-i 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.

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 speci-
fied in thenmbd.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 mes-
sage-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 re-
ply "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 con-
nected 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 jo-
bid specified.

jobdelete printername unixjobid
Send a job delete change notify message for the printer and unix jo-
bid 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.

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 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 ver-
