Using SSHTunnelForwarder to connect to a MySQL db via SSH

I am trying to connect to a mysql db over ssh in python, but am getting an error. I have the following saved in a python file 'forward.py'. My code is as follows: forward.py from sshtunnel import SSHTunnelForwarder import MySQLdb with SSHTunnelForwarder( ('ssh_host', 22), ssh_password="ssh_password", ssh_username="ssh_username", remote_bind_address=('mysql_host', 3306)) as server: con = MySQLdb.connect(user='mysql_username',passwd='mysql_password',db='mysql_db_name',host='mysql_host',port=server.local_bind_port) When I run forward.py in terminal, I receive the following error: _mysql_exceptions.OperationalError: (2003, "Can't connect to MySQL server on 'mysql_host' (60)") It is worth noting that the values are hardcoded values for security, i.e. 'mysql_host' is an actual host that I can ssh to just fine when I run ssh mysql_host via terminal. I can also connect just fine using Sequel Pro with the same values, as per: http://screencast.com/t/0niuWlMDb Can anyone point me in the right direction? Thanks in advance
