9 smbcontrol [-i] [-s]
10 smbcontrol [destination] [message-type] [parameter]
12
14 This tool is part of the samba(7) suite.
15 smbcontrol is a very small program, which sends messages to a smbd(8),
17 a nmbd(8), or a winbindd(8) daemon running on the system.

20 -h|--help
21 Print a summary of command line options.
22 -s|--configfile <configuration file>
24 The file specified contains the configuration details required by
25 the server. The information in this file includes server-specific
26 information such as what printcap file to use, as well as
27 descriptions of all the services that the server is to provide. See
28 smb.conf for more information. The default configuration file name
29 is determined at compile time.
30 -i
32 Run interactively. Individual commands of the form destination
33 message-type parameters can be entered on STDIN. An empty command
34 line or a "q" will quit the program.
35 destination
37 One of nmbd, smbd or a process ID.
38 The all destination causes the message to "broadcast" to all
40 running daemons including nmbd and winbind. This is a change for
41 Samba 3.3, prior to this the parameter smbd used to do this.
42 The smbd destination causes the message to be sent to the smbd
44 daemon specified in the smbd.pid file.
45 The nmbd destination causes the message to be sent to the nmbd
47 daemon specified in the nmbd.pid file.
48 The winbindd destination causes the message to be sent to the
50 winbind daemon specified in the winbindd.pid file.
51 If a single process ID is given, the message is sent to only that
53 process.
54 message-type
56 Type of message to send. See the section MESSAGE-TYPES for details.
57 parameters
59 any parameters required for the message-type
60
62 Available message types are:
63 close-share
65 Order smbd to close the client connections to the named share. Note
66 that this doesn´t affect client connections to any other shares.
67 This message-type takes an argument of the share name for which
68 client connections will be closed, or the "*" character which will
69 close all currently open shares. This may be useful if you made
70 changes to the access controls on the share. This message can only
71 be sent to smbd.
72 debug
74 Set debug level to the value specified by the parameter. This can
75 be sent to any of the destinations. If this message is sent to
76 either the smbd or winbindd daemons, the parent process will
77 rebroadcast the message to all child processes changing the debug
78 level in each one.
79 force-election
81 This message causes the nmbd daemon to force a new browse master
82 election.
83 ping
85 Send specified number of "ping" messages and wait for the same
86 number of reply "pong" messages. This can be sent to any of the
87 destinations.
88 profile
90 Change profile settings of a daemon, based on the parameter. The
91 parameter can be "on" to turn on profile stats collection, "off" to
92 turn off profile stats collection, "count" to enable only
93 collection of count stats (time stats are disabled), and "flush" to
94 zero the current profile stats. This can be sent to any smbd or
95 nmbd destinations.
96 debuglevel
98 Request debuglevel of a certain daemon and write it to stdout. This
99 can be sent to any of the destinations.
100 profilelevel
102 Request profilelevel of a certain daemon and write it to stdout.
103 This can be sent to any smbd or nmbd destinations.
104 printnotify
106 Order smbd to send a printer notify message to any Windows NT
107 clients connected to a printer. This message-type takes the
108 following arguments:
109 queuepause printername
111 Send a queue pause change notify message to the printer
112 specified.
113 queueresume printername
115 Send a queue resume change notify message for the printer
116 specified.
117 jobpause printername unixjobid
119 Send a job pause change notify message for the printer and unix
120 jobid specified.
121 jobresume printername unixjobid
123 Send a job resume change notify message for the printer and
124 unix jobid specified.
125 jobdelete printername unixjobid
127 Send a job delete change notify message for the printer and
128 unix jobid specified.
129 Note that this message only sends notification that an event has
131 occured. It doesn´t actually cause the event to happen.
132 This message can only be sent to smbd.
134 samsync

148 available if samba is built with dmalloc support.
149 dmalloc-log-changed
151 Dump the pointers that have changed since the mark set by
152 dmalloc-mark. Can be sent to both smbd and nmbd. Only available if
153 samba is built with dmalloc support.
154 shutdown
156 Shut down specified daemon. Can be sent to both smbd and nmbd.
157 pool-usage
159 Print a human-readable description of all talloc(pool) memory usage
160 by the specified daemon/process. Available for both smbd and nmbd.
161 drvupgrade

164 local version of the driver. Can only be sent to smbd.
165 reload-config

177 The original Samba software and related utilities were created by
178 Andrew Tridgell. Samba is now developed by the Samba Team as an Open
179 Source project similar to the way the Linux kernel is developed.
180 The original Samba man pages were written by Karl Auer. The man page
182 sources were converted to YODL format (another excellent piece of Open
183 Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and
184 updated for the Samba 2.0 release by Jeremy Allison. The conversion to
185 DocBook for Samba 2.2 was done by Gerald Carter. The conversion to
186 DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
