45
46 <para><command>nmblookup</command> is used to query NetBIOS names
47 and map them to IP addresses in a network using NetBIOS over TCP/IP
48 queries. The options allow the name queries to be directed at a
49 particular IP broadcast area or to a particular machine. All queries
50 are done over UDP.</para>

63 <constant>__MSBROWSE__</constant>. Please note that in order to
64 use the name "-", you need to make sure "-" isn't parsed as an

75 the normal (broadcast responding) NetBIOS processing code
76 on a machine is used instead. See RFC1001, RFC1002 for details.

93 where it ignores the source port of the requesting packet
94 and only replies to UDP port 137. Unfortunately, on most UNIX
95 systems root privilege is needed to bind to this port, and
96 in addition, if the <citerefentry><refentrytitle>nmbd</refentrytitle>
97 <manvolnum>8</manvolnum></citerefentry> daemon is running on this machine it also binds to this port.

176 <para><command>nmblookup</command> can be used to query
177 a WINS server (in the same way <command>nslookup</command> is
178 used to query DNS servers). To query a WINS server, <command>nmblookup</command>
179 must be called like this:</para>
180
181 <para><command>nmblookup -U server -R 'name'</command></para>
182
183 <para>For example, running :</para>
184
185 <para><command>nmblookup -U samba.org -R 'IRIX#1B'</command></para>
186
187 <para>would query the WINS server samba.org for the domain
188 master browser (1B name type) for the IRIX workgroup.</para>

209 <para>The original Samba software and related utilities
210 were created by Andrew Tridgell. Samba is now developed
211 by the Samba Team as an Open Source project similar
212 to the way the Linux kernel is developed.</para>
213
214 <para>The original Samba man pages were written by Karl Auer.
215 The man page sources were converted to YODL format (another
216 excellent piece of Open Source software, available at <ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
217 ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
218 release by Jeremy Allison. The conversion to DocBook for
219 Samba 2.2 was done by Gerald Carter. The conversion to DocBook
220 XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.</para>
