Cara yang digunakan untuk mengetahui webserver dari KPU adalah menTELNET port webserver yaitu port 80,
kemudian saya menggunakan perintah GET/ PEMILU.HTML untuk mendapatkan halaman web
namun server web mereply Bad Request 400, yang artinya halaman yang dimaksud tidak ada
Dari respon server dapat diketahui bahwa webserver yang digunakan adalah nginx 0.6.35
Berikut dibawah ini adalah hasil telnet port 80nya
====================================
root@X-Mobile:/home/cyclops# telnet www.kpu.go.id 80
Trying 203.130.201.130…
Connected to www.kpu.go.id.
Escape character is ‘^]’.
GET/ PEMILU.HTML
<html>
<head><title>400 Bad Request</title></head>
<body bgcolor=”white”>
<center><h1>400 Bad Request</h1></center>
<hr><center>nginx/0.6.35</center>
</body>
</html>
Connection closed by foreign host.
========================================
Sekarang untuk mencari tahu server yang digunakan, menggunakan tools nmap
dengan perintah nmap -A www.kpu.go.id -PN
dari hasilnya diketahui bahwa 98% kemungkinan KPU menggunakan server FreeBSD 6.2-Release
Berikut dibawah ini adalah hasil nmapnya
