For debugging, check your web server's error log.	[reply]

I'm sure your webserver process have no rights to access /root folder.	[reply]

Could you please tell me how to give access permission for the root folder as my webserver process have no rights to access /root folder. Don't. On most Unix systems there's dedicated place for stuff like that, and it's `/var/www/` or `/srv/www/`. Use that instead of fiddling with you root user's home directory.	[reply] [d/l] [select]

What do you see in the server logs? Perl reduces RSI - it saves typing	[reply]

You should discover that the opendir call is failing. Unless the security of your web server is horribly messed up, the web server will not have any access to the /root directory. You might want to make a separate top level directory and give the web server's account (usually apache or httpd) the appropriate access to it.	[reply]
