nmbscan - Network Shares Scanner Based On NMB/SMB/NetBIOS Protocol

NMB Scanner scans the shares of a NetBIOS/SMB network, using the NMB/SMB/NetBIOS protocols. It is useful for acquiring information on a local area network for such purposes as security auditing.

It can obtain such information as NMB/SMB/NetBIOS/Windows hostname, IP address, IP hostname, ethernet MAC address, Windows username, NMB/SMB/NetBIOS/Windows domain name, and master browser. It can discover all the NMB/SMB/NetBIOS/Windows hosts on a local area network by using the hosts lists maintained by master browsers.

You can download the version 1.2.6 of nmbscan tool from HERE.

After downloading, extract the files by typing:

mkdir nmbscan && tar -xvf nmbscan-1.2.6.tar.gz --directory nmbscan

Running nmbscan shows pretty much of information about the usage.
