Nbtscan is a  program for scanning networks for NetBIOS name information.  It  works very quickly and can be usefull for information gathering about the network you are connected to.  Nbtscan is not installed by default in Ubuntu so you will have to install it.  Use synaptic or just use the command

sudo apt-get install nbtscan

I have made a script and put it in my /home/drew/bin/ directory so that all I have to do is type the name of the script into a terminal and I get instant results.

  Here is a copy of my script

#! /bin/bash
sudo nbtscan -hv 192.168.1.0/24 > test.txt && mousepad test.txt

This will send the output to a text file and open it with mousepad ( which is not installed by default as well - Just use gedit if you want to)

The reason I use mousepad is to demonstrate how quickly the nbtscan actually runs.

  Try typing

man nbtscan

into a terminal to learn more about this program.

  Test it for yourself and have fun with it.

   Feel free to comment or make a suggestion.
