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
|
|

|
|
reply to broadcast queries for its own name(s). Additional
|
|
names for <B

|
|
(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
|

server.</P
