Name
smbcontrol — send messages to smbd, nmbd or winbindd processes
Synopsis
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 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 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 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
Force daemon to reload smb.conf configuration file. Can be sent
to smbd, nmbd, or winbindd.

the Samba suite.
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 DocBook XML 4.2 for
Samba 3.0 was done by Alexander Bokovoy.
