Command synopsis

findsmb [subnet_broadcast_address]

If a different subnet’s broadcast address is provided, it will find SMB servers on that subnet. If no subnet broadcast address is supplied, findsmb will look on the local subnet.

The output from findsmb looks like this:

$ findsmb
                                *=DMB
                                +=LMB
