nmblookup |
The nmblookup program is a client program that allows command-line access to NetBIOS name service for resolving NetBIOS computer names into IP addresses. The program works by broadcasting its queries on the local subnet until a machine with the specified name responds. You can think of it as a Windows analog of nslookup or dig . This is useful for looking up regular computer names, as well as special-purpose names, such as _ _MSBROWSE_ _ . If you wish to query for a particular type of NetBIOS name, add the NetBIOS type to the end of the name, using the format netbios_name #< dd > .
nmblookup [options] netbios_name
Interprets netbios_name as an IP address and does a node status query on it.
Sends the query to the given broadcast address. The default is to send the query to the broadcast address of the primary network interface.
Sets the debug (sometimes called logging) level. The level can range from 0 to 10. Debug level 0 logs only the most important messages. Level 1 is normal; levels 3 and above are primarily used by developers for debugging the nmblookup program itself and slow the program considerably.
Prints the flags in the packet headers.
Prints command-line usage information for the program.
Sets a NetBIOS scope identifier. NetBIOS scope is a rarely used precursor to workgroups.
Searches for a local master browser by looking up netbios_name <1d> . If netbios_name is specified as a dash ( - ), a lookup is done on the special name _ _MSBROWSE_ _ .
Sets the "recursion desired" bit in the packet. This causes the system that responds to try a WINS lookup and return the address and any other information the WINS server has saved.
Uses the root port of 137. This option exists as a bug workaround for Windows 95. This option might require the user to be superuser.
Performs a node status query once the name query has returned an IP address. This returns all the resource types that the system knows about, including their numeric attributes. For example:
$ nmblookup -S toltec querying toltec on 172.16.1.255 172.16.1.1 toltec<00> Looking up status of 172.16.1.1 TOLTEC <00> - M <ACTIVE> TOLTEC <03> - M <ACTIVE> TOLTEC <20> - M <ACTIVE> ..__MSBROWSE__. <01> - <GROUP> M <ACTIVE> METRAN <00> - <GROUP> M <ACTIVE> METRAN <1b> - M <ACTIVE> METRAN <1c> - <GROUP> M <ACTIVE> METRAN <1d> - M <ACTIVE> METRAN <1e> - <GROUP> M <ACTIVE>
Specifies the location of the Samba configuration file. Although the file defaults to /usr/local/samba/lib/smb.conf , you can override it here on the command line. Normally used for debugging.
Translates IP addresses into resolved names.
Performs a unicast query to the specified address. Used with -R to query WINS servers.
Note that nmblookup has no option for setting the workgroup. You can get around this by putting workgroup = workgroup_name in a file and passing it to nmblookup with the -s option.
