nbmac V1.03 (1998-11-06)

Function

Displays MAC address of a network card.

Format

nbmac [-lana_num] [NetBIOS_name]

lana_num default is -0)
NetBIOS_name must be a valid NetBIOS name on your network.

Comments

This program calls NetBIOS interrupt 0x5C function 0x33 which makes it independend of network hardware and software used as long as there is a NetBIOS network. nbmac returns 00:00:00:00:00:00 if no NetBIOS compatible network is loaded (eg. plain MS-DOS). If nbmac returns no ouput at all something really odd must have happened. Should you seriously need a more detailed error message, please contact me for terms. This program should work with any NetBIOS compatible network under Microsoft MS-DOS, Microsoft Windows 95, Microsoft Windows NT and IBM OS/2. Please let me know about your experiences with a configuration other than one mentioned below.

Please add the following informations to your reports:

• Operating system and version (eg. Microsoft MS-DOS 5.0)
• Network software and version (eg. Digital PATHWORKS for DOS 4.0)
• Network protocol used (eg. DECnet)
• Network type used (eg. Ethernet)
• Which MAC-address did nbmac return? (eg. 00:A0:24:CA:EA:D2)
• Comments (eg. "When trying to query a remote NetBIOS nam, the program hung the computer.")

This program has been successfully tested under the following configurations:

ncmac hangs your computer (only?) under Microsoft MS-DOS and Digital PATHWORKS when trying to query remote servers. It returns a local MAC address fine, though. Digital PATHWORKS for VAX/VMS V4.x servers also did not reply to queries.
