freehosting123 SQL server problem?

hi…. i am using freehosting123.com and i suddenly got an error message from wordpress like that,

—
Error establishing a database connection

This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at localhost. This could mean your host’s database server is down.

is there anyone using freehosting123 facing the same problem or is it just me? because when i tried to login the freehosting123 account, it says

“Warning: mysql_connect(): Can’t connect to local MySQL server through socket ‘/var/tmp/mysql.sock’ (2) in /home/freehost/public_html/inc/sqlinf.php on line 36
Connect Error: Can’t connect to local MySQL server through socket ‘/var/tmp/mysql.sock’ (2)”

and i couldn’t login to my ftp either! i am dying to post something… i just hope everything would be alright…
