Easy as 1,2,3
root@192.168.0.139's password:
Ada kata-2 "Easy as 1,2,3"
Hmm kita coba knock port 1, 2, 3 ...
port knocking
Lakukan,
nmap -Pn --host-timeout 201 --max-retries 0 -p 1 192.168.0.139 nmap -Pn --host-timeout 201 --max-retries 0 -p 2 192.168.0.139 nmap -Pn --host-timeout 201 --max-retries 0 -p 3 192.168.0.139
Naga-naganya port knocking untuk membuka / menghidupkan web :) ..
lakukan nmap lagi
Lakukan
nmap -sT -p- -A 192.168.0.139
