NBTScan

NBTScan is a handy tool for scanning your network to get NetBIOS name info. Basically, it sends out status queries to every address in a range you choose and then displays the info in an easy-to-read format. You can see details like the IP address, the NetBIOS computer name, who’s logged in, and even the MAC address for each host that responds.

Compatibility with Different Systems

NBTScan works on both Unix and Windows systems. I’ve tried it on several versions like Windows NT 4.0, Windows 2000, FreeBSD 4.3, OpenBSD 2.8, and RedHat Linux versions 7.1 and 7.3. It should also run smoothly on Solaris and other Linux distributions!

History of NBTScan

This program has a bit of history! Steve Coleman helped port earlier versions to Solaris, HP-UX, and OSF/1 while also fixing some bugs along the way. He even got it running on IRIX/SGI with just a few hiccups. Other users have reported success getting NBTScan to work on AIX and SunOS as well.

Fast Reports

The cool thing about NBTScan is that it’s a successor to an older Perl script with the same name but runs much faster! When you run it, you get reports that look something like this:

IP address       NetBIOS Name     Server    User             MAC address

------------------------------------------------------------------------------

192.168.1.2      MYCOMPUTER                 JDOE             00-a0-c9-12-34-56

192.168.1.5      WIN98COMP          RROE             00-a0-c9-78-90-00

192.168.1.123    DPTSERVER          ADMINISTRATOR    08-00-09-12-34-56

The first column shows the IP address of each responding host, while the second gives you its computer name.

Diving Deeper with Options

If you add a -v switch when running NBTScan, you'll get a detailed list of all NetBIOS names for each responding address!

NetBIOS Name Table for Host 192.168.1.123:

Name             Service          Type

----------------------------------------

DPTSERVER        < 00 >             UNIQUE

DPTSERVER        < 20 >             UNIQUE
