	<title>DESCRIPTION</title>
	<para>This program is part of the <citerefentry><refentrytitle>samba</refentrytitle>
	<manvolnum>7</manvolnum></citerefentry> suite.</para>

	<para><command>samba</command> is the server daemon that
	provides Active Directory, filesharing and printing services to clients.
	The server provides filespace and directory services to
	clients using the SMB (or CIFS) protocol and other
	related protocols such as DCE/RPC, LDAP and Kerberos.
	</para>

	<para>
	Clients supported include MSCLIENT 3.0 for DOS, Windows for
	Workgroups, Windows 95/98/ME, Windows NT, Windows 2000/XP/2003,
	OS/2, DAVE for Macintosh, and cifsfs for Linux.</para>

	<para>An extensive description of the services that the
	server can provide is given in the man page for the
	configuration file controlling the attributes of those
	services (see <citerefentry><refentrytitle>smb.conf</refentrytitle>
	<manvolnum>5</manvolnum></citerefentry>.  This man page will not describe the
	services, but will concentrate on the administrative aspects
	of running the server.
	</para>

	<para>Please note that there are significant security
	implications to running this server, and the <citerefentry><refentrytitle>smb.conf</refentrytitle>
	<manvolnum>5</manvolnum></citerefentry> manual page should be regarded as mandatory reading before
	proceeding with installation.
	</para>

	<title>OPTIONS</title>

	<variablelist>
		<varlistentry>
		<term>-D|--daemon</term>
		<listitem><para>If specified, this parameter causes
		the server to operate as a daemon. That is, it detaches
		itself and runs in the background, fielding requests
		on the appropriate ports. Operating the server as a
		daemon is the recommended way of running
		<command>samba</command> for servers that provide more
		than casual use file and print services.  This switch is
		assumed if <command>samba</command> is executed on the
		command line of a shell.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-i|--interactive</term>
		<listitem><para>If this parameter is specified it causes the
		server to run "interactively", not as a daemon, even if the
		server is executed on the command line of a shell. Setting this
		parameter negates the implicit daemon mode when run from the
		command line. <command>samba</command> also logs to standard
                output, as if the <command>-S</command> parameter had been
                given.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-M|--model</term>
		<listitem><para>This parameter can be used to specify the
		&quot;process model&quot; samba should use. This determines
		how concurrent clients are handled. Available process
		models include:
		<itemizedlist>
			<listitem><para><emphasis>single</emphasis></para>
			<para>All Samba services run in a single process. This is
			not recommended for production configurations.
			</para></listitem>

			<listitem><para><emphasis>standard</emphasis></para>
			<para>A process is created for each Samba service,
			and for those services that support it (currently only
			LDAP and NETLOGON) a new processes is started
			for each new client connection.</para>

			<para>Historically, this was the 'standard' way Samba behaved
			up until v4.10. Note that this model can be resource intensive
			if you have a large number of client connections.</para>
			</listitem>

			<listitem><para><emphasis>prefork</emphasis></para>
			<para>The default. A process is started for each Samba service,
			and a fixed number of worker processes are started for those
			services that support it (currently LDAP, NETLOGON, and KDC).
			The client connections are then shared amongst the worker
			processes.
			Requests for services not supporting prefork are handled
			by a single process for that service.</para>
			<para>The number of prefork worker processes started is
			controlled by the
			<citerefentry><refentrytitle>smb.conf</refentrytitle>
			<manvolnum>5</manvolnum></citerefentry> parameter
		        <smbconfoption name="prefork children"/>,
			which defaults to 4.
			</para></listitem>
		</itemizedlist>
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>--maximum-runtime=seconds</term>
		<listitem><para>Set maximum runtime of the server process till
		autotermination in seconds.
		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term>-b|--show-build</term>

		<para>If running the server as a daemon at startup,

		</varlistentry>

		<varlistentry>
		<term><filename>/etc/services</filename></term>
		<listitem><para>If running the server via the
		meta-daemon <command>inetd</command>, this file
		must contain a mapping of service name (e.g., netbios-ssn)

		</para></listitem>
		</varlistentry>

		<varlistentry>
		<term><filename>/usr/local/samba/lib/smb.conf</filename></term>
		<listitem><para>This is the default location of the <citerefentry><refentrytitle>smb.conf</refentrytitle>

	<title>DIAGNOSTICS</title>

	<para>Most diagnostics issued by the server are logged
	in a specified log file. The log file name is specified
	at compile time, but may be overridden on the command line.</para>

	<para>The number and nature of diagnostics available depends
	on the debug level used by the server. If you have problems, set
	the debug level to 3 and peruse the log files.</para>

	<para>Most messages are reasonably self-explanatory. Unfortunately,
	at the time this man page was created, there are too many diagnostics
	available in the source code to warrant describing each and every
	diagnostic. At this stage your best bet is still to grep the
	source code and inspect the conditions that gave rise to the
	diagnostics you are seeing.</para>
