netcat trick 1
by Didik
Untuk melakukan scan port dengan netcat (gunakan nc)
user@localhost:~$ nc -v -n -z 127.0.0 1-1024
v itu verbose n itu no resolve z itu zero (used for scanning)
Perintah diatas akan muncul sebagai berikut, kalau tidak ketik dua kali v nya agar makin verbose
user@localhost:~$ nc -vv -n -z 127.0.0.1 1-1024
