NAME
       nmblookup4 - NetBIOS over TCP/IP client used to lookup NetBIOS names

SYNOPSIS
       nmblookup4 [-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}

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

       nmblookup4 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.

OPTIONS
       -M
	   Searches for a master browser by looking up the NetBIOS 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 :
	   nmblookup4 -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 running
	   a WINS server and the user wishes to query the names in the WINS
	   server. If this bit is unset the normal (broadcast responding)
	   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 ignores the
	   source port of the requesting packet and only replies to UDP port
	   137. Unfortunately, on most UNIX systems root privilege 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 port.

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

       -B <broadcast address>
	   Send the query to the given broadcast address. Without this option
	   the default behavior of nmblookup4 is to send the query to the
	   broadcast address of the network interfaces as either auto-detected
	   or defined in the interfaces[1] parameter of the smb.conf(5) file.

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

       -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
	   each

	   IP address .... NetBIOS name

	   pair that is the normal output.

       -f
	   Show which flags apply to the name that has been looked up.
	   Possible 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 previous
	   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.

EXAMPLES
       nmblookup4 can be used to query a WINS server (in the same way nslookup
       is used to query DNS servers). To query a WINS server, nmblookup4 must
       be called like this:

       nmblookup4 -U server -R 'name'

       For example, running :

       nmblookup4 -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.

VERSION
       This man page is correct for version 3 of the Samba suite.

AUTHOR
       The original Samba software and related utilities were created by
       Andrew 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/[2]) and
       updated 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
       DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
