Print a summary of command line options.

Display brief usage message.

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.

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.

Prints the program version number.

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.

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.

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.

Set timeout to seconds.

One of nmbd, smbd, winbindd 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.

Type of message to send. See the section MESSAGE-TYPES for details.

any parameters required for the message-type

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.

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.

Order smbd to close the client connections from a given IP address. This message-type takes an argument of the IP address from which client connections will be closed. This message can only be sent to smbd.

This message causes the nmbd daemon to force a new browse master election.

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.

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.

Request debuglevel of a certain daemon and write it to stdout. This can be sent to any of the destinations.

Request profilelevel of a certain daemon and write it to stdout. This can be sent to any smbd or nmbd destinations.

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

queueresume printername

jobpause printername unixjobid

jobresume printername unixjobid

jobdelete printername unixjobid

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.

Set a mark for dmalloc. Can be sent to both smbd and nmbd. Only available if samba is built with dmalloc support.

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.

Shut down specified daemon. Can be sent to both smbd and nmbd.

Print a human-readable description of all talloc(pool) memory usage by the specified daemon/process. Available for both smbd and nmbd.

Force clients of printers using specified driver to update their local version of the driver. Can only be sent to smbd.

Force daemon to reload smb.conf configuration file. Can be sent to smbd, nmbd, or winbindd.

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

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

flush [uid|gid]

delete <ID>

kill <ID>

Query the number of smbd child processes. This message can only be sent to smbd.
