findsmb - list info about machines that respond to SMB name queries on a subnet
findsmb [subnetbroadcastaddress]
DESCRIPTION
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.
OPTIONS
-r 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.
subnet broadcast address
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.
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 work-
group. 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
