Question

I want to connect trough SSH channel to mysql database on the server.

I have downloaded this SSH.Net library.

This is what I have tried and I thought it will work after my secured connection has been established.

My SSH connection is established but normal connection to database is not executed.

So check my code please:

using (var client = new SshClient("cpanel****", "******", "******"))
          {
            client.Connect();
            con = new MySqlConnection(GetConnectionString());
            con.Open();
            cmd = new MySqlCommand(String.Format("insert into {0} values (null, ?Parname , ?Parname2, ?Parname3, ?Parname4, ?Parname5, ?Parname6, ?Parname7);", ConfigSettings.ReadSetting("main")), con);
            cmd.Parameters.Add("?Parname", MySqlDbType.Double).Value = Math.Round(deciLat, 5);
            // ... more parameters
            cmd.ExecuteNonQuery();
            client.Disconnect();
           }

Here is a tutorial http://georgelantz.com/2007/09/10/access-mysql-through-ssh-tunnel-in-a-windows-net-application/ which sounds reasonable.

Basic idea is to establish an SSH connection with a tunnel (aka port forwarding) and then point your MySQL connection to localhost.

SSH tunnel redirects connections to localhost:XX to the ssh server port:YY. So your port YY will be the mysql connection port, and in your connection string you would use localhost:XX.

The SSH library you are using also seems to support port forwarding, so you might be able to get that working as well.
