Uploading my dynamic site to Netfirms MySQL

I created a dynamic site in CS5.5, using XAMPP to make it locally. After putting it on my Netfirms-hosted remote server, I get an error saying:

Warning: mysql_pconnect() [function.mysql-pconnect]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /hermes/bosweb26c/b2801/nf.myurl/Connections/my_url.php on line 9

Fatal error: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /hermes/bosweb26c/b2801/nf.myurl/Connections/my_url.php on line 9

Basically what I did, was export all the phpMyAdmin info into the MySQL that Netfirms hosts, and this happened. Can anyone help me, please?

Thanks.
