Homepage of NMBscan

Here you can see from where you are comming from, dear visitors (since january 2008)  :

summary

nmbscan scans the shares of a SMB/NetBIOS 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.
