Host Discovery
ARP
arp-scan
Active:
$ sudo arp-scan -l [-s <SPOOFED_IP>] -v
$ sudo arp-scan -I eth0 192.168.0.0/24
netdiscover
Passive:
$ sudo netdiscover -i eth0 -r 192.168.0.0/24 -p
Active, sending 20 requests per IP:
$ sudo netdiscover -i eth0 -r 192.168.0.0/24 -c 20
Hunt for Subnets
Take 10.0.0.0/8 as an example:
$ sudo nmap -n -sn 10.0-255.0-255.1 -oA subnets/gateways -PE [--min-rate 10000 --min-hostgroup 10000]
$ grep 'Up' subnets/gateways.gnmap | cut -d' ' -f2 > subnets/ranges.txt
$ sed -i subnets/ranges.txt -e 's/$/\/24/'
Ping Sweep
Bash:
$ NET="0.0.0"; for i in $(seq 1 254); do (ping -c1 -W1 $NET.$i > /dev/null && echo "$NET.$i" | tee -a sweep.txt &); done
Or
$ NET="0.0.0"; for i in $(seq 1 254); do (ping -c1 -W1 "$NET.$i" | grep 'bytes from' | cut -d' ' -f4 | cut -d':' -f1 | tee -a sweep.txt &); done
$ sort -u -t'.' -k4,4n sweep.txt > hosts/targets.txt && rm sweep.txt
Batch:
Cmd > set "NET=10.5.5" && for /L %i in (1,1,255) do @ping -n 1 -w 200 %NET%.%i > nul && echo %NET%.%i > sweep.txt
PowerShell (option 1):

Host discovery flag:
nmap -sn ... == nmap -PS443 -PA80 -PE -PP ...

-PE/PP/PM: ICMP echo, timestamp, and netmask request discovery probes

Search for Nmap NSE scripts:
$ find /usr/share/nmap/scripts/ -type f | grep smb
Or
$ sudo nmap --script-updatedb
$ cat /usr/share/nmap/scripts/script.db | grep smb
Configure Nmap to run as unprivileged user by setting Linux capabilities:
$ sudo setcap cap_net_raw,cap_net_admin,cap_net_bind_service+eip `which nmap`
$ nmap --privileged ...
Grep only numbers to get a comma-separated list of ports:
$ cat nmap/initial.nmap | egrep -o '^[0-9]{1,5}' | awk -F/ '{ print $1 }' ORS=','; echo
Define which NSE scripts were ran:
$ grep '|_' services/alltcp-versions.nmap | cut -d'_' -f2 | cut -d' ' -f1 | sort -u | grep ':'
Look at HTTP titles:
$ grep -i 'http-title' services/alltcp-versions.nmap
