findsmb - list info about machines that respond to SMB name queries on
findsmb [subnet broadcast address]
This perl 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.
-r Controls whether findsmb takes bugs in Windows95 into account
when trying to find a Netbios name registered of the remote ma-
chine. 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.
subnet broadcast address
Without this option, findsmb will probe the subnet of the ma-
chine wherefindsmb(1) is run. This value is passed tonm-
blookup(1) as part of the -B option.
The output of findsmb lists the following information for all machines
that respond to the initialnmblookup 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 Work-
groups, 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)run-
ning. If nmbd is running on the system, you will only get the IP ad-
dress 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

The original Samba software and related utilities were created by An-
drew 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 up-
dated 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 Doc-
Book XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
