Salam kepada semua blogger sekelian. Kalau korang perasan dan banyak perubahan aku buat kat blog aku ni. Hehehe.. grafik tu aku edit guna GIMP 2.0. Goodbye to Photoshop.. hehehe..

Hmm.. lama sungguh aku tak update blog ni. Bukan apa.. takder kesempatan. Lepas dah kahwin ni bz jer manjang. Dah lama aku tinggalkan aktiviti hack mengehack, blog memblog.. hehehe.. rindu gak kat geng-geng hm. Anyway u guys alwoays r0x!

Nanti ada masa aku upload gambar-gambar kahwin.

Ok.. post kali ni aku nak kongsi satu script whois yang ditulis dalam php. Konsep dia mudah ajer.Korang tahu tak whois tu apa?

WHOIS (pronounced who is) is a query/response protocol which is widely used for querying databases in order to determine the registrant or assignee of Internet resources, such as a domain name, an IP address, or an autonomous system number. WHOIS lookups were traditionally performed with a command line interface application, and network administrators predominantly still use this method, but many simplified web-based tools now exist. WHOIS typically is transported with the Transmission Control Protocol (TCP) and server implementations listen to requests on the well-known port number 43.

Ok, script ni aku query server whois mynic. Tapi diorang dah tukar nama dah kepada whois.domainregistry.my.

So mula-mula aku telnet port 43, nak pastikan service ni open.

Ok..skang ni part code nya.. hehehe

  
<br /><form>
<br />Domain: <input type="text" name="query" value="<?echo $query?>">
<br /><input type="submit" value=" Go ">
<br /></form>
<br /><?php
<br />$server = "whois.mynic.net.my";
<br />function whois_request($server, $query){
<br />$data = "";
<br />$fp = fsockopen($server, 43);
<br />if($fp) {
<br />fputs($fp, $query."\r\n");
<br />while(!feof($fp)) {
<br />$data .= fread($fp, 1000); }
<br />fclose($fp); }
<br />return $data; }
<br />
<br />if (isset($_REQUEST['query'])){
<br />$data = whois_request($server, $query);
<br />echo("Domain: $query");
<br />echo("<br>Maklumat:<p><pre>$data<pre></br>"); }
<br />?>
<br />

Ok.. ni pulak hasilnya.

So apa gunanya maklumat ni kepada hackers ? Hehehe.. korang pikir sendiri la...
