Netdiscover - Active/Passive ARP Scanner

Netdiscover - Active/Passive ARP
Scanner

Netdiscover is an active/passive
address reconnaissance tool,
mainly developed for those
wireless networks without dhcp
server, when you are wardriving.
It can be also used on hub/
switched networks. Built on top
of libnet and libpcap, it can
passively detect online hosts, or
search for them, by actively
sending arp requests, it can also
be used to inspect your network
arp traffic, or find network
addresses using auto scan mode,
which will scan for common local
networks
Open your backtrack terminal
and type
Netdiscover –I eth2 –r
192.168.0.100/24
Usage:
netdiscover [-i device] [-r range |
-p] [-s time] [-n node] [-c count]
[-f] [-S]
-i device: your network device
-r range: scan a given range
instead of auto scan.

-p passive mode do not send
anything, only sniff
-s time: time to sleep between
each arp request (miliseconds)
-c count: number of times to
send each arp reques (for nets
with packet loss)
-n node: last ip octet used for
scanning (from 2 to 253)
-S enable sleep time supression
betwen each request (hardcore
mode)
-f enable fastmode scan, saves a
lot of time, recommended for
auto
