<title>DESCRIPTION</title>
<para>This tool is part of the <ulink url="samba.7.html">
Samba</ulink> suite.</para>
<para><command>nmblookup</command> 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.</para>
</refsect1>
<refsect1>
<title>OPTIONS</title>
<variablelist>
<varlistentry>
<term>-M</term>
<listitem><para>Searches for a master browser by looking
up the NetBIOS name <replaceable>name</replaceable> with a
type of <constant>0x1d</constant>. If <replaceable>
name</replaceable> is "-" then it does a lookup on the special name
<constant>__MSBROWSE__</constant>.</para></listitem>
</varlistentry>
<varlistentry>
<term>-R</term>
<listitem><para>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.
</para></listitem>
</varlistentry>
<varlistentry>
<term>-S</term>
<listitem><para>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.
</para></listitem>
</varlistentry>
<varlistentry>
<term>-r</term>
<listitem><para>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 <ulink url="nmbd.8.html">nmbd(8)</ulink>
daemon is running on this machine it also binds to this port.
</para></listitem>
</varlistentry>
<varlistentry>
<term>-A</term>
<listitem><para>Interpret <replaceable>name</replaceable> as
an IP Address and do a node status query on this address.</para>
</listitem>
</varlistentry>
<varlistentry>
<term>-h</term>
<listitem><para>Print a help (usage) message.</para></listitem>
</varlistentry>
<varlistentry>
<term>-B <broadcast address></term>
<listitem><para>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 <ulink
url="smb.conf.5.html#INTERFACES"><parameter>interfaces</parameter>
</ulink> parameter of the <filename>smb.conf (5)</filename> file.
</para></listitem>
</varlistentry>
<varlistentry>
<term>-U <unicast address></term>
<listitem><para>Do a unicast query to the specified address or
host <replaceable>unicast address</replaceable>. This option
(along with the <parameter>-R</parameter> option) is needed to
query a WINS server.</para></listitem>
</varlistentry>
<varlistentry>
<term>-d <debuglevel></term>
<listitem><para>debuglevel is an integer from 0 to 10.</para>
<para>The default value if this parameter is not specified
is zero.</para>
<para>The higher this value, the more detail will be logged
about the activities of <command>nmblookup</command>. At level
0, only critical errors and serious warnings will be logged.</para>
<para>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.</para>
<para>Note that specifying this parameter here will override
the <ulink url="smb.conf.5.html#LOGLEVEL"><parameter>
log level</parameter></ulink> parameter in the <filename>
smb.conf(5)</filename> file.</para></listitem>
</varlistentry>
<varlistentry>
<term>-s <smb.conf></term>
<listitem><para>This parameter specifies the pathname to
the Samba configuration file, <ulink url="smb.conf.5.html">
smb.conf(5)</ulink>. This file controls all aspects of
the Samba setup on the machine.</para></listitem>
</varlistentry>
<varlistentry>
<term>-i <scope></term>
<listitem><para>This specifies a NetBIOS scope that
<command>nmblookup</command> 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
<emphasis>very</emphasis> rarely used, only set this parameter
if you are the system administrator in charge of all the
NetBIOS systems you communicate with.</para></listitem>
</varlistentry>
<varlistentry>
<term>-T</term>
<listitem><para>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</para>
<para><emphasis>IP address .... NetBIOS name</emphasis></para>
<para> pair that is the normal output.</para></listitem>
</varlistentry>
<varlistentry>
<term>name</term>
<listitem><para>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.</para></listitem>
</varlistentry>
</variablelist>
</refsect1>
<refsect1>
<title>EXAMPLES</title>
<para><command>nmblookup</command> can be used to query
a WINS server (in the same way <command>nslookup</command> is
used to query DNS servers). To query a WINS server,
<command>nmblookup</command> must be called like this:</para>
<para><command>nmblookup -U server -R 'name'</command></para>
<para>For example, running :</para>
<para><command>nmblookup -U samba.org -R 'IRIX#1B'</command></para>
<para>would query the WINS server samba.org for the domain
master browser (1B name type) for the IRIX workgroup.</para>

<title>VERSION</title>
<para>This man page is correct for version 2.2 of
the Samba suite.</para>

<title>AUTHOR</title>
<para>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.</para>
<para>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
<ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
release by Jeremy Allison. The conversion to DocBook for
Samba 2.2 was done by Gerald Carter</para>
