113 <listitem><para>Order smbd to close the client
114 connections to the named share. Note that this doesn't affect client
115 connections to any other shares. This message-type takes an argument of the
116 share name for which client connections will be closed, or the
117 "*" character which will close all currently open shares.
118 This may be useful if you made changes to the access controls on the share.
119 This message can only be sent to <constant>smbd</constant>.</para>
125 <listitem><para>Set debug level to the value specified by the
126 parameter. This can be sent to any of the destinations. If this
127 message is sent to either the smbd or winbindd daemons, the parent
128 process will rebroadcast the message to all child processes changing
129 the debug level in each one.</para>
134 <term>kill-client-ip</term>
135 <listitem><para>Order smbd to close the client connections from a
136 given IP address. This message-type takes an argument of the IP
137 address from which client connections will be closed. This message

153 any of the destinations.</para>
159 <listitem><para>Change profile settings of a daemon, based on the
160 parameter. The parameter can be "on" to turn on profile stats
161 collection, "off" to turn off profile stats collection, "count"
162 to enable only collection of count stats (time stats are
163 disabled), and "flush" to zero the current profile stats. This can
164 be sent to any smbd or nmbd destinations.</para>

168 <term>debuglevel</term>

332 <title>AUTHOR</title>
334 <para>The original Samba software and related utilities
335 were created by Andrew Tridgell. Samba is now developed
336 by the Samba Team as an Open Source project similar
337 to the way the Linux kernel is developed.</para>
339 <para>The original Samba man pages were written by Karl Auer.
340 The man page sources were converted to YODL format (another
341 excellent piece of Open Source software, available at <ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
342 ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
343 release by Jeremy Allison. The conversion to DocBook for
344 Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for
345 Samba 3.0 was done by Alexander Bokovoy.</para>
