How to override drupal front page node.tpl file ? I tried various
   node--front.tpl.php
   page--node--front.tpl.php
   page--front--node.tpl.php
but its not working.
What will be the file name to override home page node ? (I am working in drupal 7)
You can add this function to theme template.php
   function customethemename_preprocess_node ( &$vars ) {
        if ($vars["is_front"]) {
           $vars["theme_hook_suggestions"][] = "node__front";
        }  
    }
Then you can page page--front.tpl.php
It will solve the problem
It should be page--front.tpl.php
Also, be sure that you have the precursors in the hierarchy for your theme (e.g. page.tpl.php)
