NAME
       netdiscover - an active/passive arp reconnaissance tool.

SYNOPSIS
       netdiscover  [-i	 device] [-r range | -l file | -p] [-s time] [-n node]
       [-c count] [-f] [-d] [-S] [-P] [-L]

DESCRIPTION
       netdiscover is an active/passive	 arp  reconnaissance  tool,  initially
       developed  to  gain  information	 about	wireless networks without dhcp
       servers in wardriving scenarios. It can also be used on	switched  net‐
       works.  Built  on  top  of  libnet and libpcap, it can passively detect
       online hosts or search for them by sending arp requests.

       Furthermore, it can be used to inspect your network's arp  traffic,  or
       find network addresses using auto scan mode, which will scan for common
       local networks.

OPTIONS
       -i device
	      The network interface to sniff and inject packets. If no	inter‐
	      face is specified, first available will be used.

       -r range
	      Scan a given range instead of auto scan. Valid range values area
	      for example: 192.168.0.0/24, 192.168.0.0/16 or 192.168.0.0/8.

       -l file Scan ranges contained on the given file, it must
	      contain one range per line.

       -p     Enable passive mode. In passive mode, netdiscover does not  send
	      anything, but does only sniff.

       -s time
	      Sleep given time in milliseconds between each arp request injec‐
	      tion. (default 1)

       -c count
	      Number of times to send each arp request.	 Useful	 for  networks
	      with packet loss, so it will scan given times for each host.

       -n node
	      Last ip octet of the source ip used for scanning. You can change
	      it if the default host is already used.  (allowed	 range:	 2  to
	      253, default 66)

       -S     Enable sleep time suppression between each request. If set, net‐
	      discover will sleep after having scanned 255  hosts  instead  of
	      sleeping	after  each one. This mode was used in netdiscover 0.3
	      beta4 and before. Avoid this  option  in	networks  with	packet
	      loss,  or	 in  wireless  networks	 with  low signal level. (also
	      called hardcore mode)

       -f     Enable fast mode scan. This will only scan for .1, .100 and .254
	      on  each network. This mode is useful while searching for ranges
	      being used. After you found such range you can make  a  specific
	      range scan to find online boxes.

       -d     Ignore  configuration  files at home dir, this will use defaults
	      ranges and ips for autoscan and fast mode. See below for	infor‐
	      mation about configuration files.

       -P     Produces	output	suitable  to  be  redirected into a file or be
	      parsed by another program, instead of  using  interactive	 mode.
	      Enabling this option, netdiscover will stop after scanning given
	      ranges.

       -L     When using -P, continue program execution after the active  scan
	      phase to capture ARP packets passively.

USAGE
       If  passive mode (-p), scan list (-l) or scan range (-r) options aren't
       enabled, netdiscover will scan for common lan addresses.

       Screen control keys

       h      Show help screen

       j      Scroll down (or down arrow)

       k      Scroll up (or up arrow)

       a      Show arp replies list

       r      Show arp requests list

       q      Close help screen or end application

CONFIG FILES
       There are 2 configuration files that netdiscover will  look  for,  each
       time  it is executed, if file doesn't exist it will use default values.
       You can use the -d switch to disable reading and loading	 configuration
       files.

       ~/.netdiscover/ranges
	      This file contains a list of ranges (one per line) used for auto
	      scan mode instead of default ranges. By default netdiscover will
	      use a list of common ranges used on local networks.

	      Example:
	       192.168.21.0/24
	       172.26.0.0/16
	       10.0.0.0/8

       ~/.netdiscover/fastips
	      List containing the last octect of the ips to be scanned on each
	      subnet, when using fast mode, by default (1,100,154).

	      Example:
	       1
	       10
	       25
	       254
