To get access to the server over the network you need to do a little adjustment:
Open /etc/mysql/my.cnf and comment out the line skip-networking so that it looks like #skip-networking.
Don't forget to save ;) Now you have to restart the mysql server.
I do it this way:
killall -9 safe_mysqld
killall -9 mysqld
/etc/init.d/mysql start
