findsmb

Name

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

Synopsis

findsmb [subnet broadcast address]

DESCRIPTION

This perl script is part of the Samba 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.

OPTIONS

subnet broadcast address

Without this option, findsmb will probe the subnet of the machine where findsmb is run. This value is passed to nmblookup as part of the -B option.

EXAMPLES

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 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, Windows 95 or Windows 98 will not show any information about the operating system or server version.

The command must be run on a system without nmbd 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.

For example, running findsmb on a machine without nmbd running would yield output similar to the following

AUTHOR

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
