NAME

       smbcontrol - send messages to smbd, nmbd or winbindd processes

SYNOPSIS

       smbcontrol [-s] [-t|--timeout]

       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

       -?|--help
           Print a summary of command line options.

       --usage
           Display brief usage message.

       -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.

       -d|--debuglevel=level
           level is an integer from 0 to 10. The default value if this parameter is not specified
           is 1.

           The higher this value, the more detail will be logged to the log files about the
           activities of the server. At level 0, only critical errors and serious warnings will
           be logged. Level 1 is a reasonable level for day-to-day running - it generates a small
           amount of information about operations carried out.

           Levels above 1 will generate considerable amounts of log data, and should only be used
           when investigating a problem. Levels above 3 are designed for use only by developers
           and generate HUGE amounts of log data, most of which is extremely cryptic.

           Note that specifying this parameter here will override the log level parameter in the
           smb.conf file.

       -V|--version
           Prints the program version number.

       -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.

       -l|--log-basename=logdirectory
           Base directory name for log/debug files. The extension ".progname" will be appended
           (e.g. log.smbclient, log.smbd, etc...). The log file is never removed by the client.

       --option=<name>=<value>
           Set the smb.conf(5) option "<name>" to value "<value>" from the command line. This
           overrides compiled-in defaults and options read from the configuration file.

       -t|--timeout
           Set timeout to seconds.

       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 occurred. It doesn't
           actually cause the event to happen.

           This message can only be sent to smbd.

       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.

       reload-printers
           Force smbd to reload printers. Can only be sent to smbd.

       idmap
           Notify about changes of id mapping. Can be sent to smbd or (not implemented yet)
           winbindd.

           flush [uid|gid]
               Flush caches for sid <-> gid and/or sid <-> uid mapping.

           delete <ID>
               Remove a mapping from cache. The mapping is given by <ID> which may either be a
               sid: S-x-..., a gid: "GID number" or a uid: "UID number".

           kill <ID>
               Remove a mapping from cache. Terminate smbd if the id is currently in use.

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.
