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.
