.SH "NAME"
findsmb \- list info about machines that respond to SMB name queries on a subnet
.SH "SYNOPSIS"
.HP \w'\ 'u
findsmb [subnet\ broadcast\ address]
.SH "DESCRIPTION"
.PP
This perl script is part of the
\fBsamba\fR(7)
suite\&.
.PP
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
\fBnmblookup\fR(1)
and
\fBsmbclient\fR(1)
to obtain this information\&.
.SH "OPTIONS"
.PP
\-r
.RS 4
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,
\fBnmblookup\fR(1)
will be called with
\fB\-B\fR
option\&.
.RE
.PP
subnet broadcast address
.RS 4
Without this option,
findsmb
will probe the subnet of the machine where
\fBfindsmb\fR(1)
is run\&. This value is passed to
\fBnmblookup\fR(1)
as part of the
\fB\-B\fR
option\&.
.RE
.SH "EXAMPLES"
.PP
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\&.
.PP
There will be a \*(Aq+\*(Aq in front of the workgroup name for machines that are local master browsers for that workgroup\&. There will be an \*(Aq*\*(Aq 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\&.
.PP
The command with
\fB\-r\fR
option must be run on a system without
\fBnmbd\fR(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
\fB\-r\fR
option on a machine without
nmbd
running\&.
.PP
For example, running
findsmb
without
\fB\-r\fR
option set would yield output similar to the following
.sp
.if n \{\
.RS 4
.\}
.nf

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\&.
