Usage:
nbtscan [-v] [-d] [-e] [-l] [-t timeout] [-b bandwidth] [-r] [-q] [-s separator] [-m retransmits] (-f filename)|(<scan_range>)
-v verbose output. Print all names received
from each host
-d dump packets. Print whole packet contents.
-e Format output in /etc/hosts format.
-l Format output in lmhosts format.
Cannot be used with -v, -s or -h options.
-t timeout wait timeout milliseconds for response.

-b bandwidth Output throttling. Slow down output
so that it uses no more that bandwidth bps.

respond to this only.
You need to be root to use this option on Unix.

-m retransmits Number of retransmits. Default 0.
-f filename Take IP addresses to scan from file filename.
-f - makes nbtscan take IP addresses from stdin.
