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 <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 descrip‐
27 tions 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 mes‐
33 sage-type parameters can be entered on STDIN. An empty command line
34 or a "q" will quit the program.
35 destination
37 One of nmbd, smbd or a process ID.
38 The smbd destination causes the message to "broadcast" to all smbd
40 daemons.
41 The nmbd destination causes the message to be sent to the nmbd dae‐
43 mon specified in the nmbd.pid file.
44 If a single process ID is given, the message is sent to only that
46 process.
47 message-type
49 Type of message to send. See the section MESSAGE-TYPES for details.
50 parameters
52 any parameters required for the message-type
53
55 Available message types are:
56 close-share
58 Order smbd to close the client connections to the named share. Note
59 that this doesn't affect client connections to any other shares.
60 This message-type takes an argument of the share name for which
61 client connections will be closed, or the "*" character which will
62 close all currently open shares. This may be useful if you made
63 changes to the access controls on the share. This message can only
64 be sent to smbd.
65 debug
67 Set debug level to the value specified by the parameter. This can be
68 sent to any of the destinations.
69 force-election
71 This message causes the nmbd daemon to force a new browse master
72 election.
73 ping
75 Send specified number of "ping" messages and wait for the same num‐
76 ber of reply "pong" messages. This can be sent to any of the desti‐
77 nations.
78 profile
80 Change profile settings of a daemon, based on the parameter. The
81 parameter can be "on" to turn on profile stats collection, "off" to
82 turn off profile stats collection, "count" to enable only collection
83 of count stats (time stats are disabled), and "flush" to zero the
84 current profile stats. This can be sent to any smbd or nmbd destina‐
85 tions.
86 debuglevel
88 Request debuglevel of a certain daemon and write it to stdout. This
89 can be sent to any of the destinations.
90 profilelevel
92 Request profilelevel of a certain daemon and write it to stdout.
93 This can be sent to any smbd or nmbd destinations.
94 printnotify
96 Order smbd to send a printer notify message to any Windows NT
97 clients connected to a printer. This message-type takes the follow‐
98 ing arguments:
99 queuepause printername
102 Send a queue pause change notify message to the printer speci‐
103 fied.
104 queueresume printername
106 Send a queue resume change notify message for the printer
107 specified.
108 jobpause printername unixjobid
110 Send a job pause change notify message for the printer and
111 unix jobid specified.
112 jobresume printername unixjobid
114 Send a job resume change notify message for the printer and
115 unix jobid specified.
116 jobdelete printername unixjobid
118 Send a job delete change notify message for the printer and
119 unix jobid specified.
120 Note that this message only sends notification that an event has
122 occured. It doesn't actually cause the event to happen.
123 This message can only be sent to smbd.
125 samsync
127 Order smbd to synchronise sam database from PDC (being BDC). Can
128 only be sent to smbd.
129 Note

134 Send sam replication message, with specified serial. Can only be
135 sent to smbd. Should not be used manually.
136 dmalloc-mark
138 Set a mark for dmalloc. Can be sent to both smbd and nmbd. Only
139 available if samba is built with dmalloc support.
140 dmalloc-log-changed
142 Dump the pointers that have changed since the mark set by dmalloc-
143 mark. Can be sent to both smbd and nmbd. Only available if samba is
144 built with dmalloc support.
145 shutdown
147 Shut down specified daemon. Can be sent to both smbd and nmbd.
148 pool-usage
150 Print a human-readable description of all talloc(pool) memory usage
151 by the specified daemon/process. Available for both smbd and nmbd.
152 drvupgrade
154 Force clients of printers using specified driver to update their
155 local version of the driver. Can only be sent to smbd.
156 reload-config
158 Force daemon to reload smb.conf configuration file. Can be sent to
159 smbd, nmbd, or winbindd.

168 The original Samba software and related utilities were created by
169 Andrew Tridgell. Samba is now developed by the Samba Team as an Open
170 Source project similar to the way the Linux kernel is developed.
171 The original Samba man pages were written by Karl Auer. The man page
173 sources were converted to YODL format (another excellent piece of Open
174 Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and
175 updated for the Samba 2.0 release by Jeremy Allison. The conversion to
176 DocBook for Samba 2.2 was done by Gerald Carter. The conversion to Doc‐
177 Book XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
