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

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

79 <para>The <parameter>winbindd</parameter> destination causes the
80 message to be sent to the winbind daemon specified in the

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>

124 parameter. This can be sent to any of the destinations.</para>

131 force a new browse master election. </para>

146 parameter. The parameter can be "on" to turn on profile stats
147 collection, "off" to turn off profile stats collection, "count"
148 to enable only collection of count stats (time stats are
149 disabled), and "flush" to zero the current profile stats. This can

290 <title>AUTHOR</title>
292 <para>The original Samba software and related utilities
293 were created by Andrew Tridgell. Samba is now developed
294 by the Samba Team as an Open Source project similar
295 to the way the Linux kernel is developed.</para>
297 <para>The original Samba man pages were written by Karl Auer.
298 The man page sources were converted to YODL format (another
299 excellent piece of Open Source software, available at <ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
300 ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
301 release by Jeremy Allison. The conversion to DocBook for
302 Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for
303 Samba 3.0 was done by Alexander Bokovoy.</para>
