	<para><command>smbcontrol</command> is a very small program, which

	<manvolnum>8</manvolnum></citerefentry>, a <citerefentry><refentrytitle>nmbd</refentrytitle>
	<manvolnum>8</manvolnum></citerefentry>, or a <citerefentry><refentrytitle>winbindd</refentrytitle>

	<para>Available message types are:</para>

	<variablelist>
	<varlistentry><term>close-share</term>
	<listitem><para>Order smbd to close the client 
	connections to the named share. Note that this doesn't affect client 
	connections to any other shares. This message-type takes an argument of the
	share name for which client connections will be closed, or the
	"*" character which will close all currently open shares.
	This may be useful if you made changes to the access controls on the share.
	This message can only be sent to <constant>smbd</constant>.</para>
	</listitem>
	</varlistentry>

	<varlistentry><term>close-denied-share</term>
	<listitem><para>Behave like <constant>close-share</constant>,
	but don't disconnect users that are still allowed to access
	the share. It can safely be sent to all smbds after changing
	share access controls. It will only affect users who have been
	denied access since having connected initially. This message
	can only be sent to <constant>smbd</constant>.</para>
	</listitem>
	</varlistentry>

	<varlistentry>
	<term>debug</term>
	<listitem><para>Set debug level to the value specified by the 
	parameter. This can be sent to any of the destinations. If this
	message is sent to either the smbd or winbindd daemons, the parent
	process will rebroadcast the message to all child processes changing
	the debug level in each one.</para>
