>DESCRIPTION</H2
><P
>This program is part of the Samba suite.</P
><P
><B
CLASS="COMMAND"
>nmbd</B
> is a server that understands
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, 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 <EM
>-n</EM
>
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"
TARGET="_top"
><TT
CLASS="FILENAME"
> smb.conf(5)</TT
></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 WIN
server.</P
