Type

External MS-DOS program

Format

nbmac [-lana_num] [-b] [-s] [-u] [-c|-i|-l|-r] [NetBIOS_name]

-lana_num (0..255) - default is -0 -b batch mode (set NBMAC=...) -s scan (starts at lana_num) -u upper case MAC format -c Cisco MAC format (xxxx.xxxx.xxxx) -i IEEE MAC format (XX-XX-XX-XX-XX-XX) - default -l colon MAC format (xx:xx:xx:xx:xx:xx) -r raw MAC format (xxxxxxxxxxxx)

NNetBIOS_name must be a valid NetBIOS name on your network.
Options -b, -s -lana_num -u can be combined.
Only one of the options -c, -i, -l and -r can be given but they can be combined with any other option.

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.

When reporting please make sure to include the following:

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)
cmments (eg. "when trying to query a remote NetBIOS name, the program hung the computer.")

ncmac does not run under Microsoft 64-bit operating systems. Microsoft servers with 64-bit operating systems can be queried.

ncmac does not work under Microsoft MS-DOS and Digital PATHWORKS, if a server is given. nbmac returns the local MAC address.
Digital PATHWORKS for VAX/VMS V4.x servers do not return anything.
Samba servers return 00-00-00-00-00-00
