list info about machines that respond to SMB name queries on a subnet

smbclient - nmblookup
[subnet broadcast address]
add an example, a script, a trick and tips
The output of 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
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 command with -r option must be run on a system without
nmbd(8) running. If nmbd is running on the system, you
will only get the IP address and the DNS name of the machine. To
get proper responses from Windows 95 and Windows 98 machines, the
command must be run as root and with -r option on a
machine without nmbd running.
For example, running findsmb without -r option set would
yield output similar to the following
IP ADDR NETBIOS NAME WORKGROUP/OS/VERSION

script is part of the samba(7) suite.
findsmb is a
perl script that prints out several pieces of information
about machines on a subnet that respond to SMB name query
requests. It uses nmblookup(1) and
smbclient(1) to obtain this information.
Controls whether findsmb takes
bugs in Windows95 into account when trying to find a Netbios
name registered of the remote machine. This option is
disabled by default because it is specific to Windows 95 and
Windows 95 machines only. If set, nmblookup(1) will
be called with -B option.
Without this option, findsmb
will probe the subnet of the machine where findsmb(1)
is run. This value is passed to nmblookup(1) as part
of the -B option.
This man page is correct for version 3 of the Samba suite.

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
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
