       nmblookup - NetBIOS over TCP/IP client used to lookup NetBIOS names

       nmblookup [-M] [-R] [-S] [-r] [-A] [-h] [-B <broadcast address>]
		 [-U <unicast address>] [-d <debug level>]
		 [-s <smb config file>] [-i <NetBIOS scope>] [-T] [-f] {name}

       This tool is part of the samba(7) suite.

       nmblookup  is  used to query NetBIOS names and map them to IP addresses
       in a network using NetBIOS over TCP/IP queries. The options  allow  the
       name  queries  to be directed at a particular IP broadcast area or to a
       particular machine. All queries are done over UDP.

       -M     Searches for a master browser by looking	up  the	 NetBIOS  name
	      name  with a type of 0x1d. If  name is "-" then it does a lookup
	      on the special name__MSBROWSE__. Please note that	 in  order  to
	      use  the	name "-", you need to make sure "-" isn't parsed as an
	      argument, e.g. use :nmblookup -M -- -.

       -R     Set the recursion desired bit in the packet to  do  a  recursive
	      lookup. This is used when sending a name query to a machine run‐
	      ning a WINS server and the user wishes to query the names in the
	      WINS server. If this bit is unset the normal (broadcast respond‐
	      ing) NetBIOS processing code on a machine is used	 instead.  See
	      RFC1001, RFC1002 for details.

       -S     Once  the	 name  query has returned an IP address then do a node
	      status query as well. A node status query	 returns  the  NetBIOS
	      names registered by a host.

       -r     Try  and bind to UDP port 137 to send and receive UDP datagrams.
	      The reason for this option is a bug in Windows 95 where  it  ig‐
	      nores  the source port of the requesting packet and only replies
	      to UDP port 137. Unfortunately, on most UNIX systems root privi‐
	      lege  is	needed	to  bind to this port, and in addition, if the
	      nmbd(8) daemon is running on this machine it also binds to  this

       -A     Interpret	 name  as  an IP Address and do a node status query on
	      this address.

       -n <primary NetBIOS name>
	      This option allows you to override the NetBIOS name  that	 Samba
	      uses  for itself. This is identical to setting the  parameter in
	      the smb.conf file. However, a command  line  setting  will  take
	      precedence over settings in smb.conf.

       -i <scope>
	      This specifies a NetBIOS scope that nmblookup will use to commu‐
	      nicate with when generating NetBIOS names. For  details  on  the
	      use  of NetBIOS scopes, see rfc1001.txt and rfc1002.txt. NetBIOS
	      scopes are very rarely used, only set this parameter if you  are
	      the  system  administrator  in charge of all the NetBIOS systems
	      you communicate with.

	      Set the SMB domain of the username. This overrides  the  default
	      domain  which  is	 the domain defined in smb.conf. If the domain
	      specified is the same as the servers NetBIOS name, it causes the
	      client  to log on using the servers local SAM (as opposed to the
	      Domain SAM).

       -O socket options
	      TCP socket options to set on the client socket. See  the	socket
	      options  parameter  in  the smb.conf manual page for the list of
	      valid options.

	      Print a summary of command line options.

       -B <broadcast address>
	      Send the query to the given broadcast address. Without this  op‐
	      tion  the	 default behavior of nmblookup is to send the query to
	      the broadcast address of the network interfaces  as  either  au‐
	      to-detected  or  defined	in  the	 interfaces  parameter	of the
	      smb.conf(5) file.

       -U <unicast address>
	      Do a unicast query to the specified address or host unicast  ad‐
	      dress. This option (along with the -R option) is needed to query
	      a WINS server.

       -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-spe‐
	      cific 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.

	      debuglevel 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 crit‐
	      ical 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  pa‐
	      rameter in the smb.conf file.

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

       -T     This causes any IP addresses found in the lookup to be looked up
	      via a reverse DNS lookup into a DNS name, and printed out before

	      IP address .... NetBIOS name

	      pair that is the normal output.

       -f     Show which flags apply to the name that has been looked up. Pos‐
	      sible  answers  are  zero	 or  more of: Response, Authoritative,
	      Truncated, Recursion_Desired, Recursion_Available, Broadcast.

       name   This is the NetBIOS name being queried. Depending upon the  pre‐
	      vious  options  this  may	 be a NetBIOS name or IP address. If a
	      NetBIOS name then the different name types may be	 specified  by
	      appending	 '#<type>'  to	the  name.  This name may also be '*',
	      which will return all registered names within a broadcast area.

       nmblookup can be used to query a WINS server (in the same way  nslookup
       is  used	 to query DNS servers). To query a WINS server, nmblookup must
       be called like this:

       nmblookup -U server -R 'name'

       For example, running :

       nmblookup -U samba.org -R 'IRIX#1B'

       would query the WINS server samba.org for the domain master browser (1B
       name type) for the IRIX workgroup.

       This man page is correct for version 3.0 of the Samba suite.

       nmbd(8), samba(7), and smb.conf(5).

       The  original  Samba software and related utilities were created by An‐
       drew Tridgell. Samba is now developed by the  Samba  Team  as  an  Open
       Source project similar to the way the Linux kernel is developed.

       The  original  Samba  man pages were written by Karl Auer. The man page
       sources were converted to YODL format (another excellent piece of  Open
       Source  software, available at ftp://ftp.icce.rug.nl/pub/unix/) and up‐
       dated for the Samba 2.0 release by Jeremy Allison.  The	conversion  to
       DocBook for Samba 2.2 was done by Gerald Carter. The conversion to Doc‐
       Book XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
