Java IP Scanner and Port Scanner Source Code

Tidak ada komentar
Pada source code di atas masih permulaan sehingga perlu pembenahan dan penyesuaian sana-sini. Misalnya seperti imputan list IP address dan Port yang akan discan. Silahkan dikembangkan menjadi tool yang berguna. Memang tidak secangging nmap-nya Fyodor sih, tapi untuk sekedar saranya explorasi. Yak, Happy Hacking Code. :)
