6 findsmb - list info about machines that respond to SMB name queries on
7 a subnet
8
10 findsmb [subnet broadcast address]
11
13 This perl script is part of the samba(7) suite.
14 findsmb is a perl script that prints out several pieces of information
16 about machines on a subnet that respond to SMB name query requests. It
17 uses nmblookup(1) and smbclient(1) to obtain this information.
18
20 -r
21 Controls whether findsmb takes bugs in Windows95 into account when
22 trying to find a Netbios name registered of the remote machine.
23 This option is disabled by default because it is specific to
24 Windows 95 and Windows 95 machines only. If set, nmblookup(1) will
25 be called with -B option.
26 subnet broadcast address
28 Without this option, findsmb will probe the subnet of the machine
29 where findsmb(1) is run. This value is passed to nmblookup(1) as
30 part of the -B option.
31
33 The output of findsmb lists the following information for all machines
34 that respond to the initial nmblookup for any name: IP address, NetBIOS
35 name, Workgroup name, operating system, and SMB server version.
36 There will be a '+' in front of the workgroup name for machines that
38 are local master browsers for that workgroup. There will be an '*' in
39 front of the workgroup name for machines that are the domain master
40 browser for that workgroup. Machines that are running Windows for
41 Workgroups, Windows 95 or Windows 98 will not show any information
42 about the operating system or server version.
43 The command with -r option must be run on a system without nmbd(8)
45 running. If nmbd is running on the system, you will only get the IP
46 address and the DNS name of the machine. To get proper responses from
47 Windows 95 and Windows 98 machines, the command must be run as root and
48 with -r option on a machine without nmbd running.
49 For example, running findsmb without -r option set would yield output
51 similar to the following
52 IP ADDR NETBIOS NAME WORKGROUP/OS/VERSION

73 The original Samba software and related utilities were created by
74 Andrew Tridgell. Samba is now developed by the Samba Team as an Open
75 Source project similar to the way the Linux kernel is developed.
