DESCRIPTION

This program is part of the Samba(7) suite.

nmbd 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, Windows XP and LanManager clients. It also participates in the browsing protocols which make up the Windows "Network Neighborhood" view.

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.

Amongst other services, nmbd will + IP number a specified host is using.

Amongst other services, nmbd 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 -n - option (see OPTIONS below). Thus nmbd will + option (see OPTIONS below). Thus nmbd will reply to broadcast queries for its own name(s). Additional - names for nmbd to respond on can be set - via parameters in the smb.conf(5) configuration file.

nmbd can also be used as a WINS + names for nmbd to respond on can be set + via parameters in the smb.conf(5) configuration file.

nmbd 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.

In addition, nmbd can act as a WINS + replying to queries from clients for these names.

In addition, nmbd 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.

OPTIONS

If specified, this parameter causes - nmbd to operate as a daemon. That is, + nmbd to operate as a daemon. That is, it detaches itself and runs in the background, fielding - requests on the appropriate port. By default, nmbd + requests on the appropriate port.

-F

If specified, this parameter causes - the main nmbd process to not daemonize, + the main nmbd process to not daemonize, i.e. double-fork and disassociate with the terminal.

-S

If specified, this parameter causes - nmbd to log to standard output rather + nmbd to log to standard output rather than a file.

-i

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. nmbd also logs to standard - output, as if the -S parameter had been + command line. nmbd also logs to standard + output, as if the -S parameter had been given.
