Hello!

I have tried the following setup:

server: MySQL 4.0.20 with native OpenSSL 0.9.7d support on Linux client: MySQL 4.0.20 without SSL support, through stunnel 4.0.5 on WinXP

As it can be suspected from the above, I was trying to use the mysqld with ssl support directly as the server side of the connection, without stunnel. I saw a pseudo-https client solution in the stunnel docs where this approach seemed to work.

The client stunnel.conf:

cert = client-test.crt key = client-test.key client = yes debug = debug [mysqlclient] accept = 3306 connect = server.host.fqdn:3306

The mysql client reported the following error, right after asking for the password:

ERROR 2013: Lost connection to MySQL server during query

Here is the log from the client stunnel:

What is wrong here?

Thank you!
