-
- <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>

- <constant>__MSBROWSE__</constant>. Please note that in order to

- <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>The original Samba software and related utilities

- 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. The conversion to DocBook
- XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.</para>
