Connect to MySQl database on a server

[eluser]leet_2k[/eluser]
Hi there,
I am trying to connect to a database that is currently on my work's team dev server from home. Is that possible?
I have tried with following settings:-

$db['default']['hostname'] = "http://abcdev.com.au/";
$db['default']['username'] = "username";
$db['default']['password'] = "password";
$db['default']['database'] = "abc";
$db['default']['dbdriver'] = "mysql";

I get error that the Database connection error has occured.

Please help.
