NMBLOOKUP !!!NMBLOOKUP NAME SYNOPSIS DESCRIPTION OPTIONS EXAMPLES VERSION SEE ALSO AUTHOR ---- !!NAME nmblookup - NetBIOS over TCP/IP client used to lookup NetBIOS names !!SYNOPSIS __nmblookup__ [[ __-M__ ] [[ __-R__ ] [[ __-S__ ] [[ __-r__ ] [[ __-A__ ] [[ __-h__ ] [[ __-B __ ] [[ __-U __ ] [[ __-d __ ] [[ __-s __ ] [[ __-i __ ] [[ __-T__ ] __name__ !!DESCRIPTION This tool is part of the Sambasuite. __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. !!OPTIONS __-M__ Searches for a master browser by looking up the NetBIOS name ''name'' with a type of 0x1d. If ''name'' is '' __-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. __-h__ Print a help (usage) message. __-B __ Send the query to the given broadcast address. Without this option the default behavior of nmblookup is to send the query to the broadcast address of the network interfaces as either auto-detected or defined in the ''interfaces'' parameter of the ''smb.conf (5)'' file. __-U __ 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. __-d __ 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 about the activities of __nmblookup__. At level 0, only critical errors and serious warnings will be logged. 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 data, most of which is extremely cryptic. Note that specifying this parameter here will override the ''log level''parameter in the ''smb.conf(5)'' file. __-s __ This parameter specifies the pathname to the Samba configuration file, smb.conf(5). This file controls all aspects of the Samba setup on the machine. __-i __ This specifies a NetBIOS scope that __nmblookup__ will use to communicate 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. __-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. __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 '# !!EXAMPLES __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. !!VERSION This man page is correct for version 2.2 of the Samba suite. !!SEE ALSO __nmbd(8)__, samba(7) !!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/ ----
