Searches for a master browser by looking up the NetBIOS

\fB0x1d\fR\&. If
|

\fI name\fR

is "\-" then it does a lookup on the special name

\fB__MSBROWSE__\fR\&. Please note that in order to use the name "\-", you need to make sure "\-" isn\*(Aqt parsed as an argument, e\&.g\&. use :

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\&.

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\&.

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
|
|
\fBnmbd\fR(8)
|
|
daemon is running on this machine it also binds to this port\&.

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

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 \*(Aq#<type>\*(Aq to the name\&. This name may also be \*(Aq*\*(Aq, which will return all registered names within a broadcast area\&.

\fBnmblookup4\fR

can be used to query a WINS server (in the same way
|
|
\fBnslookup\fR
|
|
is used to query DNS servers)\&. To query a WINS server,
|
|
\fBnmblookup4\fR

must be called like this:

.PP

\fBnmblookup4 \-U server \-R \*(Aqname\*(Aq\fR

For example, running :
|
|
.PP
|
|
\fBnmblookup4 \-U samba\&.org \-R \*(AqIRIX#1B\*(Aq\fR
|
|
.PP
|

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\&.
|
|
.PP
|
|
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
|
|
\m[blue]\fBftp://ftp\&.icce\&.rug\&.nl/pub/unix/\fR\m[]\&\s-2\u[2]\d\s+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\&.
