Public bug reported:
Ubuntu 18.04.4
man page for netdiscover doesn't describe switch -N, the switch to
suppress headers when output is sent to stdout. I have found this when I
was looking for a way how to store discovered devices to a file.
Recommended solution is to use -PN switch and redirect output to a file,
like this:
`$sudo neddiscover -i eth0 -PN | tee netdicover.log`
This is not perfect solution but it is usable. It would be nice to have
a switch that will create a detailed log file with timestamps. Such
logfile is necessary on bigger network where many devices are connected
and the discovered devices just cannot fit to a single screen...
Anyway, this bug report is about "-N" switch that is missing in manpage.
It is described at help output from netdiscover:
```
$ netdiscover -h
Netdiscover 0.3-pre-beta7 [Active/passive arp reconnaissance tool]
Written by: Jaime Penalba <jpenal...@gmail.com>
Usage: netdiscover [-i device] [-r range | -l file | -p] [-m file] [-s time]
[-n node] [-c count] [-f] [-d] [-S] [-P] [-c]
-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 the 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)
-n node: last ip octet used for scanning (from 2 to 253)
-c count: number of times to send each arp reques (for nets with packet loss)
-f enable fastmode scan, saves a lot of time, recommended for auto
-d ignore home config files for autoscan and fast mode
-S enable sleep time supression between each request (hardcore mode)
-P print results in a format suitable for parsing by another program
-N Do not print header. Only valid when -P is enabled.
-L in parsable output mode (-P), continue listening after the active scan is
completed
If -r, -l or -p are not enabled, netdiscover will scan for common lan
addresses.
```
