 Gnutella PHP,QRT example
I'm testing a PHP Gnutella client and I need to generate a QRT table so I can receive data and test the functionality. I read over the spec and I still can't figure this out or get it right. If anyone could shed some light on what I'm doing wrong that would be amazing! I suspect I'm not packing/formatting the binary data right. Here's my code: PHP Code: //write QRP reset message
$variant = "\0x0";
$table_length = pack('V',65536);
$infinity = pack('C',1);
$packet = $variant . $table_length . $infinity;
$reset = create_header( "\30x0", 1,0, $packet );
fwrite($fp, $reset,strlen($reset));
//4 kilobyte
$byte = '';
for ( $o = 0; $o < 8/*(1024*4)*/; $o++){
$byte .= 1;
//$byte .= bindec(1111);
//$byte .= pack('C',1);
}
//write qrp table
$packet = '';
for ( $t =0; $t < 16; $t++ ){
$variant = "\0x1";
$seq_no = pack('C',$ttt = $t+1);
echo "Patch $ttt of 16\n";
$seq_size = pack('C',16); //bits
$compressor = "\0x0";
$entry_bits = pack('C',8);
$packet = $variant . $seq_no . $seq_size . $compressor . $entry_bits . $byte;
$packet = create_header("\30x0",1,0,$packet);
fwrite($fp,$packet, strlen($packet));
}
