auxiliary/scanner/netbios/nbname_probe

From Metasploit Unleashed - Mastering The Framework

The "nbname_probe" auxiliary module uses sequential NetBIOS probes to determine the NetBIOS names of the remote targets.

msf > use auxiliary/scanner/netbios/nbname_probe
msf auxiliary(nbname_probe) > show options

Module options (auxiliary/scanner/netbios/nbname_probe):

   Name     Current Setting  Required  Description
   ----     ---------------  --------  -----------
   CHOST                     no        The local client address
   RHOSTS                    yes       The target address range or CIDR identifier
   RPORT    137              yes       The target port
   THREADS  1                yes       The number of concurrent threads

The only configuration we need for this module is to set our RHOSTS and THREADS values and let it run against our remote targets.

msf auxiliary(nbname_probe) > set RHOSTS 192.168.1.200-210
RHOSTS => 192.168.1.200-210
msf auxiliary(nbname_probe) > set THREADS 11
THREADS => 11
msf auxiliary(nbname_probe) > run
