Re: Cannot open connection via TCP.

[Martin Pala]

Maybe your mysql server is set to not accept TCP connections on the given 
address. You can use netstat/lsof to check whether mysql listens for 
connections and try to connect to the mysql server port for example using 
telnet to see, whether the connection can be established.
