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 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 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 destina-tions. destinations.
tions.
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 col-lection collection
lection 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 des-tinations. destinations.
tinations.
profilelevel
Request profilelevel of a certain daemon and write it to stdout. This can be sent to any smbd or
nmbd destinations.
printnotify

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 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 dae-mon/process. daemon/process.
mon/process. Available for both smbd and nmbd.
drvupgrade
Force clients of printers using specified driver to update their local version of the driver. Can
