Hi
I need to look for the range dates of access_log for example:

then write the content to another file. Date and time is very important for me to concatenate them into access_log later.

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, initialy developed to gain information about wireless networks without dhcp
servers in wardriving scenarios. It can also be used on switched networks. 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 com-
mon local networks.
OPTIONS
-i device
The network interface to sniff and inject packets. If no interface 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 injection. (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, netdiscover will sleep after having scanned 255 hosts instead of sleep-
ing 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 usefull 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 information
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 arent enabled, netdiscover will scan for common lan addresses.

h Show help screen
j Scroll down (or down arrow)
k Scroll up (or up arrow)
a Show arp replys 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 doesnt 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 contaning 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
