how to use curl request json to login to remote site

Question

I had done this:

 <?php 
       $post_body = '{"login": "injoit", "password": "injoit"}';
       $cookie_file = tempnam('/temp', 'cookie');
       $ch = curl_init('remote server login here');

       curl_setopt($ch, CURLOPT_HEADER, 0);
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
       curl_setopt($ch, CURLOPT_POST, 1);
       curl_setopt($ch, CURLOPT_POSTFIELDS, $post_body);
       curl_exec($ch);

I am getting this in response : Failed to connect to "remote server url here" port 8002: Connection timed out(7)
