40 <para><command>smbcontrol</command> is a very small program, which
41 sends messages to a <citerefentry><refentrytitle>smbd</refentrytitle>
42 <manvolnum>8</manvolnum></citerefentry>, a <citerefentry><refentrytitle>nmbd</refentrytitle>
43 <manvolnum>8</manvolnum></citerefentry>, or a <citerefentry><refentrytitle>winbindd</refentrytitle>

49 <title>OPTIONS</title>
56 <listitem><para>Run interactively. Individual commands
57 of the form destination message-type parameters can be entered
58 on STDIN. An empty command line or a "q" will quit the
59 program.</para></listitem>
63 <term>destination</term>
64 <listitem><para>One of <parameter>nmbd</parameter>, <parameter>smbd</parameter> or a process ID.</para>
66 <para>The <parameter>all</parameter> destination causes the
67 message to "broadcast" to all running daemons including nmbd and
68 winbind. This is a change for Samba 3.3, prior to this the
69 parameter smbd used to do this.</para>
71 <para>The <parameter>smbd</parameter> destination causes the
72 message to be sent to the smbd daemon specified in the
73 <filename>smbd.pid</filename> file.</para>
75 <para>The <parameter>nmbd</parameter> destination causes the
76 message to be sent to the nmbd daemon specified in the
77 <filename>nmbd.pid</filename> file.</para>
79 <para>The <parameter>winbindd</parameter> destination causes the
80 message to be sent to the winbind daemon specified in the

107 <para>Available message types are:</para>
110 <varlistentry><term>close-share</term>
111 <listitem><para>Order smbd to close the client
112 connections to the named share. Note that this doesn't affect client
113 connections to any other shares. This message-type takes an argument of the
114 share name for which client connections will be closed, or the
115 "*" character which will close all currently open shares.
116 This may be useful if you made changes to the access controls on the share.
117 This message can only be sent to <constant>smbd</constant>.</para>
123 <listitem><para>Set debug level to the value specified by the
124 parameter. This can be sent to any of the destinations. If this
125 message is sent to either the smbd or winbindd daemons, the parent
126 process will rebroadcast the message to all child processes changing
127 the debug level in each one.</para>
132 <term>force-election</term>
133 <listitem><para>This message causes the <command>nmbd</command> daemon to
134 force a new browse master election. </para>
135 </listitem></varlistentry>
140 Send specified number of "ping" messages and
141 wait for the same number of reply "pong" messages. This can be sent to
142 any of the destinations.</para>
148 <listitem><para>Change profile settings of a daemon, based on the
149 parameter. The parameter can be "on" to turn on profile stats
150 collection, "off" to turn off profile stats collection, "count"
151 to enable only collection of count stats (time stats are
152 disabled), and "flush" to zero the current profile stats. This can
153 be sent to any smbd or nmbd destinations.</para>
154 </listitem></varlistentry>
157 <term>debuglevel</term>
159 Request debuglevel of a certain daemon and write it to stdout. This
160 can be sent to any of the destinations.</para>
165 <term>profilelevel</term>
167 Request profilelevel of a certain daemon and write it to stdout.
168 This can be sent to any smbd or nmbd destinations.</para>

314 <title>AUTHOR</title>
316 <para>The original Samba software and related utilities
317 were created by Andrew Tridgell. Samba is now developed
318 by the Samba Team as an Open Source project similar
319 to the way the Linux kernel is developed.</para>
321 <para>The original Samba man pages were written by Karl Auer.
322 The man page sources were converted to YODL format (another
323 excellent piece of Open Source software, available at <ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
324 ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
325 release by Jeremy Allison. The conversion to DocBook for
326 Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for
327 Samba 3.0 was done by Alexander Bokovoy.</para>
