Netdiscover 0.5.1 [Active/passive ARP reconnaissance tool] Written by: Jaime Penalba <[email protected]> Usage: netdiscover [-i device] [-r range | -l file | -p] [-m file] [-F filter] [-s time] [-c count] [-n node] [-dfPLNS] -i device: your network device -r range: scan a given range instead of auto scan. 192.168.6.0/24,/16,/8 -l file: scan the list of ranges contained into the given file -p passive mode: do not send anything, only sniff -m file: scan a list of known MACs and host names -F filter: customize pcap filter expression (default: "arp") -s time: time to sleep between each ARP request (milliseconds) -c count: number of times to send each ARP request (for nets with packet loss) -n node: last source IP octet used for scanning (from 2 to 253) -d ignore home config files for autoscan and fast mode -f enable fastmode scan, saves a lot of time, recommended for auto -P print results in a format suitable for parsing by another program and stop after active scan -L similar to -P but continue listening after the active scan is completed -N Do not print header. Only valid when -P or -L is enabled. -S enable sleep time suppression between each request (hardcore mode) If -r, -l or -p are not enabled, netdiscover will scan for common LAN addresses.
