I am attempting to improve the internal security at our company by
requiring
SSL connections to our MySql database from ASP.Net. I have set up the
MySql server to use OpenSSL, but when I attempt to make a connection
from
the client, I get the error:

"Lost connection to MySQL server during query"

This error occurs immediately (it is not as though it timed out).

I have done various searches on this site, Google, etc and have not
found
the solution.


The MySql (Linux) server is set up as follows:

1. Created certificates in /d1/mysql/Certificates using the openssl
command as specified at http://dev.mysql.com/doc/refman/5.0/...te-certs.html:

cacert.pem
client-cert.pem
client-key.pem

2. In the /etc/my.cnf file, added the following to the [mysqld]
section:

ssl-ca=/d1/mysql/Certificates/cacert.pem
ssl-cert=/d1/mysql/Certificates/server-cert.pem
ssl-key=/d1/mysql/Certificates/server-key.pem

3. In the /etc/my.cnf file, added the following to the [client]
section:

ssl-ca=/d1/mysql/Certificates/cacert.pem
ssl-cert=/d1/mysql/Certificates/client-cert.pem
ssl-key=/d1/mysql/Certificates/client-key.pem

4. Restarted the MySql server.

Now, when I do a SHOW VARIABLES LIKE '%ssl%', I get:

Variable_name Value
have_openssl YES
have_ssl YES
ssl_ca /d1/mysql/Certificates/cacert.pem
ssl_capath ""
ssl_cert /d1/mysql/Certificates/server-cert.pem
ssl_cipher ""
ssl_key /d1/mysql/Certificates/server-key.pem


The (WinXP) client attempts to connect to the server as follows:

1. Copy the certificate and keys to the C:\junk5 folder on the client:

ca-cert.pem
client-cert.pem
client-key.pem

2. Add the following code to my C# .NET program:

MySqlConnection connection = new MySqlConnection();

connection.ConnectionString = "server=10.1.1.111;user id=myuser;
password=mypassword; database=MyDatabase; pooling=true;Protocol=SSL;";

connection.SslOptions.CACert = "file://C:\\junk5\\ca-cert.pem";
connection.SslOptions.Cert = "file://C:\\junk5\\client-cert.pem";
connection.SslOptions.Key = "file://C:\\junk5\\client-key.pem";
connection.Open();


As soon as an attempt is made to open the connection, the error

"Lost connection to MySQL server during query"

occurs. This works if I exclude setting the SslOptions and the
"Protocol=SSL;" in
the connection string.


I have opened the permissions on the certificate and key files on both
the
server and client.

Also, I am using version 5.0.41-community-log of MySql with
CoreLab MyDirect .NET for .NET 2 Professsional (DLLs are V4.30.20).


Does anyone have any idea why this does not work?
