smbcontrol(1)
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-spe-
cific 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 com-
mand 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 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 de-
tails.
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 "*" charac-
ter which will close all currently open shares. This may be use-
ful 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 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 fol-
lowing 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 dmal-
loc-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

AUTHOR
The original Samba software and related utilities were created by An-
drew 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 up-
dated 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.
