MTC problem

Fri, 8 Jun 2007 22:28

Can't seem to get it to send a message to a connection.

meh. damn insim! lol.

Anything wrong with this?



<?php 
            $packet=pack("C", 72);
            $packet.=pack("C", ISP_MTC);
            $packet.=pack("C", 0);
            $packet.=pack("C", $data['conn_num']);
            $packet.=pack("C", $data['unique_id']);
            $packet.=pack("C", 0);
            $packet.=pack("C", 0);
            $packet.=str_pad($msgtosend, 64, "\0");
?>

Im not really an expert on programming but isnt the first packet meant to be $packet.=pack("C", 72); not $packet=pack("C", 72);? (notice the dot?)

Nope

Try this;

            $packet=pack("C", 72);
            $packet.=pack("C", ISP_MTC);
            $packet.=pack("C", 0);
            $packet.=pack("C", 0); // MISSING THIS ZERO BYTE
            $packet.=pack("C", $data['conn_num']);
            $packet.=pack("C", $data['unique_id']);
            $packet.=pack("C", 0);
            $packet.=pack("C", 0);
            $packet.=str_pad($msgtosend, 64, "\0");

just another question, haha! sorry.

About conn_nums... when someone leaves, does the highest ID take that persons conn_num?

well, when someone left on the previous insim, the connection number was say 4.

Then connection number 23 (or whatever the highest was), moved into the connection 4 ID. does it do this on the new insim?

is ISP_MTC defined as 14?
and there're some mistakes, 72 bytes packet is too short in your example,
this is mine php function:



<?php 
function send_mtc (&$socket,$ucId,$plId=0,$message){
 $packet  = "";
 $packet .= pack("c", 72);
 $packet .= pack("c", 14);
 $packet .= pack("c", 0);
 $packet .= pack("c", 0);
 $packet .= pack("c", $ucId);
 $packet .= pack("c", $plId);
 $packet .= pack("c", 0);
 $packet .= pack("c", 0);
 if (strlen($message)>64){
  $message=substr($message,0,64);
 }
 $packet .= str_pad($message, 64, "\0");
  fwrite($socket, $packet, strlen($packet));
  return true;
}
?>
