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|--configfile <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 all destination causes the message to "broadcast" to all running daemons including nmbd and winbind. This is a change for Samba
	   3.3, prior to this the parameter smbd used to do this.

	   The smbd destination causes the message to be sent to the smbd daemon specified in the smbd.pid file.

	   The nmbd destination causes the message to be sent to the nmbd daemon specified in the nmbd.pid file.

	   The winbindd destination causes the message to be sent to the winbind daemon specified in the winbindd.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. If this message is sent to either
	   the smbd or winbindd daemons, the parent process will rebroadcast the message to all child processes changing the debug level in each
	   one.

       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.

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.
