|
|
and can reply to NetBIOS over IP name service requests, like
|
|
those produced by SMB/CIFS clients such as Windows 95/98/ME,
|
|
Windows NT, Windows 2000, Windows XP and LanManager clients. It also
|
|
participates in the browsing protocols which make up the
|
|
Windows "Network Neighborhood" view.</p><p>SMB/CIFS clients, when they start up, may wish to
|
|
locate an SMB/CIFS server. That is, they wish to know what
|
|
IP number a specified host is using.</p><p>Amongst other services, <b class="command">nmbd</b> will
|
|
listen for such requests, and if its own NetBIOS name is
|
|
specified it will respond with the IP number of the host it
|
|
is running on. Its "own NetBIOS name" is by
|
|
default the primary DNS name of the host it is running on,
|
|
but this can be overridden with the <span class="emphasis"><em>-n</em></span>
|
|
option (see OPTIONS below). Thus <b class="command">nmbd</b> will
|
|
reply to broadcast queries for its own name(s). Additional
|
|
names for <b class="command">nmbd</b> to respond on can be set
|
|
via parameters in the <a href="smb.conf.5.html"><span class="citerefentry"><span class="refentrytitle">smb.conf</span>(5)</span></a> configuration file.</p><p><b class="command">nmbd</b> can also be used as a WINS
|
|
(Windows Internet Name Server) server. What this basically means
|
|
is that it will act as a WINS database server, creating a
|
|
database from name registration requests that it receives and
|
|
replying to queries from clients for these names.</p><p>In addition, <b class="command">nmbd</b> can act as a WINS
|

proxy, relaying broadcast queries from clients that do

not understand how to talk the WINS protocol to a WINS

server.</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
