This is compatible - with the LanManager protocol, and can service LanManager - clients. These include MSCLIENT 3.0 for DOS, Windows for - Workgroups, Windows 95/98/ME, Windows NT, Windows 2000, - OS/2, DAVE for Macintosh, and smbfs for Linux.</p><p>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 <a href="smb.conf.5.html"><span class="citerefentry"><span class="refentrytitle">smb.conf</span>(5)</span></a>. This man page will not describe the - services, but will concentrate on the administrative aspects - of running the server.</p><p>Please note that there are significant security - implications to running this server, and the <a href="smb.conf.5.html"><span class="citerefentry"><span class="refentrytitle">smb.conf</span>(5)</span></a> manual page should be regarded as mandatory reading before - proceeding with installation.</p><p>A session is created whenever a client requests one. - Each client gets a copy of the server for each session. This - copy then services all connections made by the client during - that session. When all connections from its client are closed, - the copy of the server for that client terminates.</p><p>The configuration file, and any files that it includes, - are automatically reloaded every minute, if they change. You - can force a reload by sending a SIGHUP to the server. Reloading - the configuration file will not affect connections to any service - that is already established. Either the user will have to - disconnect from the service, or <b class="command">smbd</b> killed and restarted.</p></div><div class="refsect1" lang="en"><h2>OPTIONS</h2><div class="variablelist"><dl><dt><span class="term">-D</span></dt><dd><p>If specified, this parameter causes - the server to operate as a daemon.

The log file name is specified - at compile time, but may be overridden on the command line.</p><p>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.</p><p>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.</p></div><div class="refsect1" lang="en"><h2>SIGNALS</h2><p>Sending the <b class="command">smbd</b> a SIGHUP will cause it to - reload its <tt class="filename">smb.conf</tt> configuration - file within a short period of time.</p><p>To shut down a user's <b class="command">smbd</b> process it is recommended - that <b class="command">SIGKILL (-9)</b> <span class="emphasis"><em>NOT</em></span> - be used, except as a last resort, as this may leave the shared - memory area in an inconsistent state. The safe way to terminate - an <b class="command">smbd</b> is to send it a SIGTERM (-15) signal and wait for - it to die on its own.</p><p>The debug log level of <b class="command">smbd</b> may be raised - or lowered using <a href="smbcontrol.1.html"><span class="citerefentry"><span class="refentrytitle">smbcontrol</span>(1)</span></a> program (SIGUSR[1|2] signals are no longer - used since Samba 2.2). This is to allow transient problems to be diagnosed, - whilst still running at a normally low log level.</p><p>Note that as the signal handlers send a debug write, - they are not re-entrant in <b class="command">smbd</b>. This you should wait until - <b class="command">smbd</b> is in a state of waiting for an incoming SMB before - issuing them. It is possible to make the signal handlers safe - by un-blocking the signals before the select call and re-blocking - them after, however this would affect performance.</p></div><div class="refsect1" lang="en"><h2>SEE ALSO</h2><p><a href="hosts_access.5.html"><span class="citerefentry"><span class="refentrytitle">hosts_access</span>(5)</span></a>, <a href="inetd.8.html"><span class="citerefentry"><span class="refentrytitle">inetd</span>(8)</span></a>, <a href="nmbd.8.html"><span class="citerefentry"><span class="refentrytitle">nmbd</span>(8)</span></a>, <a href="smb.conf.5.html"><span class="citerefentry"><span class="refentrytitle">smb.conf</span>(5)</span></a>, <a href="smbclient.1.html"><span class="citerefentry"><span class="refentrytitle">smbclient</span>(1)</span></a>, <a href="testparm.1.html"><span class="citerefentry"><span class="refentrytitle">testparm</span>(1)</span></a>, <a href="testprns.1.html"><span class="citerefentry"><span class="refentrytitle">testprns</span>(1)</span></a>, and the - Internet RFC's <tt class="filename">rfc1001.txt</tt>, <tt class="filename">rfc1002.txt</tt>. - In addition the CIFS (formerly SMB) specification is available - as a link from the Web page <ulink url="http://samba.org/cifs/"> - http://samba.org/cifs/</ulink>.</p></div><div class="refsect1" lang="en"><h2>AUTHOR</h2><p>The original Samba software and related utilities - were created by Andrew Tridgell.
