Hi Guys,

Thanks for the detailed information, please let me know if I'm understanding correct.

So the Subnet changes on every 4, as in 192.168.0.0, then 192.168.4.0 as per Rudic explanation.

1 - Does that mean that the first subnet IP Range is 192.168.0.0 - 192.168.0.255 and the next range is 192.168.1.0 - 192.168.1.255 ?

2 - Does this also mean that the incremental octet will be based on the subnet mask octet, for example in this case the subnet mask octet is the 3rd octet which is .252 so the increment subnet is also the 3rd octet, meaning that if the octet was 255.252.0.0 then the IP subnet would be (ONLY FOR UNDERSTANDING) 192.0.0.0 then 192.1.0.0 ?

Please let me know if I have understood it correct.

Thank You once again..

NB: If this is true means the CISCO book has not been explaining properly because in all of their examples I have come across they have only been using the last octet and that's the reason I have been stuck in that mindset.

findsmb

FINDSMB(1)							   User Commands							FINDSMB(1)

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(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 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 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

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. The conversion to DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
