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>
57 <listitem><para>Run interactively. Individual commands
58 of the form destination message-type parameters can be entered
59 on STDIN. An empty command line or a "q" will quit the

64 <term>destination</term>
65 <listitem><para>One of <parameter>nmbd</parameter>, <parameter>smbd</parameter> or a process ID.</para>
67 <para>The <parameter>all</parameter> destination causes the
68 message to "broadcast" to all running daemons including nmbd and
69 winbind. This is a change for Samba 3.3, prior to this the
70 parameter smbd used to do this.</para>
72 <para>The <parameter>smbd</parameter> destination causes the
73 message to be sent to the smbd daemon specified in the
74 <filename>smbd.pid</filename> file.</para>
76 <para>The <parameter>nmbd</parameter> destination causes the
77 message to be sent to the nmbd daemon specified in the
78 <filename>nmbd.pid</filename> file.</para>
80 <para>The <parameter>winbindd</parameter> destination causes the
81 message to be sent to the winbind daemon specified in the

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

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