findsmb lists the following
information for all machines that respond to the initial
nmblookup for any name: IP address, NetBIOS name,
Workgroup name, operating system, and SMB server version.
There will be a '+' in front of the workgroup name for machines that are local master browsers for that workgroup. There will be an '*' in front of the workgroup name for machines that are the domain master browser for that workgroup. Machines that are running Windows for Workgroups, Windows 95 or Windows 98 will not show any information about the operating system or server version.

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.
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 ftp://ftp.icce.rug.nl/pub/unix/) 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.
