hvorfor siger den fejl?

Jeg er igang med at lave en ny hjemmeside, men allerede ved at jeg skal connecte til mysql laver den fejl :(
jeg bruger den samme måde at kalde op på som ved mine andre hjemmesider, så jeg er lidt lost hvorfor den siger fejl!

fejlen:
Warning: mysql_connect() [function.mysql-connect]: Access denied for user: 'bg2009@212.130.22.174' (Using password: YES) in /home/web/gb2009/mamster/config/db.php on line 2

Warning: mysql_select_db() [function.mysql-select-db]: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) in /home/web/gb2009/mamster/config/db.php on line 3

Warning: mysql_select_db() [function.mysql-select-db]: A link to the server could not be established in /home/web/gb2009/mamster/config/db.php on line 3
Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

connect:
<?
mysql_connect ("mysql.web10.dk","bg2009","XXXXXXXXXX");
mysql_select_db ("bg2009");
echo (mysql_error());
?>
