       nmbd  -  NetBIOS name server to provide NetBIOS over IP naming services
       to clients


       nmbd [-D] [-F] [-S] [-a] [-i] [-o] [-h] [-V] [-d <debug level>]
            [-H <lmhosts file>] [-l <log directory>] [-p <port number>]
            [-s <configuration file>]


       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

       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 by
       the netbios name in smb.conf. 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 (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 proxy, relaying broadcast queries
       from clients that do not understand how to talk the WINS protocol to  a
       WINS server.


       -D     If  specified, this parameter causesnmbd to operate as a daemon.
              That is, it detaches itself and runs in the background, fielding
              requests  on the appropriate port. By default, nmbd will operate
              as a daemon if launched from a command shell. nmbd can  also  be
              operated  from  the  inetd  meta-daemon,  although  this  is not

       -F     If specified, this parameter causes the main nmbd process to not
              daemonize,  i.e. double-fork and disassociate with the terminal.
              Child processes are still created  as  normal  to  service  each
              connection  request,  but  the  main process does not exit. This
              operation  mode  is  suitable  for  runningnmbd  under   process
              supervisors   such  as  supervise  and  svscan  from  Daniel  J.
              Bernstein’s daemontools package, or the AIX process monitor.

       -S     If specified, this  parameter  causesnmbd  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

              Print a summary of command line options.

       -H <filename>
              NetBIOS lmhosts file. The lmhosts file  is  a  list  of  NetBIOS
              names to IP addresses that is loaded by the nmbd server and used
              via the name resolution mechanism name resolve  order  described
              in smb.conf(5) to resolve any NetBIOS name queries needed by the
              server. Note that the contents of this file are NOT used by nmbd
              to  answer  any name queries. Adding a line to this file affects
              name NetBIOS resolution from this host ONLY.

              The default path to this file  is  /etc/samba/lmhosts.  See  the
              lmhosts(5) man page for details on the contents of this file.

       -V     Prints the program version number.

       -s <configuration file>
              The  file  specified contains the configuration details required
              by  the  server.  The  information   in   this   file   includes
              server-specific  information  such as what printcap file to use,
              as well as descriptions of all the services that the  server  is
              to  provide.  See  smb.conf  for  more  information. The default
              configuration file name is determined at compile time.

              level is an integer from 0 to 10.  The  default  value  if  this
              parameter is not specified is zero.

              The higher this value, the more detail will be logged to the log
              files about the activities of  the  server.  At  level  0,  only
              critical  errors and serious warnings will be logged. Level 1 is
              a reasonable level for day-to-day running - it generates a small
              amount of information about operations carried out.

              Levels  above  1 will generate considerable amounts of log data,
              and should only be used when  investigating  a  problem.  Levels
              above  3  are  designed  for use only by developers and generate
              HUGE amounts of log data, most of which is extremely cryptic.

              Note that specifying  this  parameter  here  will  override  the
              parameter in the smb.conf file.

              Base   directory   name   for  log/debug  files.  The  extension
              ".progname" will  be  appended  (e.g.  log.smbclient,  log.smbd,
              etc...). The log file is never removed by the client.

       -p <UDP port number>
              UDP port number is a positive integer value. This option changes
              the default UDP port number (normally 137) that nmbd responds to
              name queries on. Don’t use this option unless you are an expert,
              in which case you won’t need help!


              If the server is to be run by theinetd  meta-daemon,  this  file
              must contain suitable startup information for the meta-daemon.

              or whatever initialization script your system uses).

              If  running  the  server  as a daemon at startup, this file will
              need to contain an appropriate startup sequence for the  server.

              If  running the server via the meta-daemon inetd, this file must
              contain a mapping of service name (e.g., netbios-ssn) to service
              port (e.g., 139) and protocol type (e.g., tcp).

              This   is   the  default  location  of  the  smb.conf(5)  server
              configuration file.

              When run as a WINS server (see thewins support parameter in  the
              smb.conf(5)  man  page),nmbd will store the WINS database in the
              file  wins.dat  in  the  var/locks  directory  configured  under
              wherever Samba was configured to install itself.

              If  nmbd  is  acting  as  a  browse master (see the local master
              parameter in the smb.conf(5)  man  page,  nmbd  will  store  the
              browsing  database  in  the  file  browse.dat   in the var/locks
              directory configured under  wherever  Samba  was  configured  to
              install itself.


       To shut down an nmbd process it is recommended that SIGKILL (-9) NOT be
       used, except as a last resort, as this may leave the name  database  in
       an  inconsistent state. The correct way to terminate nmbd is to send it
       a SIGTERM (-15) signal and wait for it to die on its own.

       nmbd will accept SIGHUP, which will cause it to dump out its  namelists
       into  the  file namelist.debug  in the /var/run/samba directory (or the
       var/locks directory configured under wherever Samba was  configured  to
       install  itself).  This  will  also  cause  nmbd to dump out its server
       database in the log.nmb file.

       The  debug  log  level  of  nmbd  may  be  raised  or   lowered   using
       smbcontrol(1) (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.
