.SH "NAME" | |||||
nmblookup4 \- NetBIOS over TCP/IP client used to lookup NetBIOS names | |||||
.SH "SYNOPSIS" | |||||
.HP \w'\fBnmblookup4\fR\ 'u | |||||
\fBnmblookup4\fR [\-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} | |||||
.SH "DESCRIPTION" | |||||
.PP | |||||
This tool is part of the | |||||
\fBsamba\fR(7) | |||||
suite\&. | |||||
.PP | |||||
\fBnmblookup4\fR | |||||
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\&. | |||||
.SH "OPTIONS" | |||||
.PP | |||||
\-M | |||||
.RS 4 | |||||
Searches for a master browser by looking up the NetBIOS | |||||
\fIname\fR | |||||
with a type of | |||||
\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 : | |||||
\fBnmblookup4 \-M \-\- \-\fR\&. | |||||
.RE | |||||
.PP | |||||
\-R | |||||
.RS 4 | |||||
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\&. | |||||
.RE | |||||
.PP | |||||
\-S | |||||
.RS 4 | |||||
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\&. | |||||
.RE | |||||
.PP | |||||
\-r | |||||
.RS 4 | |||||
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\&. | |||||
.RE | |||||
.PP | |||||
\-A | |||||
.RS 4 | |||||
Interpret | |||||
\fIname\fR | |||||
as an IP Address and do a node status query on this address\&. | |||||
.RE | |||||
.PP | |||||
\-B <broadcast address> | |||||
.RS 4 | |||||
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 | |||||
\m[blue]\fB\fIinterfaces\fR\fR\m[]\&\s-2\u[1]\d\s+2 | |||||
parameter of the | |||||
\fBsmb.conf\fR(5) | |||||
file\&. | |||||
.RE | |||||
.PP | |||||
\-U <unicast address> | |||||
.RS 4 | |||||
Do a unicast query to the specified address or host | |||||
\fIunicast address\fR\&. This option (along with the | |||||
\fI\-R\fR | |||||
option) is needed to query a WINS server\&. | |||||
.RE | |||||
.PP | |||||
\-T | |||||
.RS 4 | |||||
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 | |||||
.sp | |||||
\fIIP address \&.\&.\&.\&. NetBIOS name\fR | |||||
.sp | |||||
pair that is the normal output\&. | |||||
.RE | |||||
.PP | |||||
\-f | |||||
.RS 4 | |||||
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\&. | |||||
.RE | |||||
.PP | |||||
name | |||||
.RS 4 | |||||
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\&. | |||||
.RE | |||||
.SH "EXAMPLES" | |||||
.PP | |||||
\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 | |||||
.PP | |||||
For example, running : | |||||
.PP | |||||
\fBnmblookup4 \-U samba\&.org \-R \*(AqIRIX#1B\*(Aq\fR | |||||
.PP | |||||
would query the WINS server samba\&.org for the domain master browser (1B name type) for the IRIX workgroup\&. | |||||
.SH "VERSION" | |||||

This man page is correct for version 3 of the Samba suite\&. | |||||

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\&. | |||||
