Question

I’m having a bit of trouble connecting to my SQL database through my C# code. I can connect to it fine using Putty and the server I am connecting to is based in Germany, I am here in the UK.

When I use Putty I use these credentials:

 Host Name:
 sample-intra.net

 Port:
 2223

And then to login using the window that opens I type

 login as: my_username
 password: my_password

then once access has been granted I type:

 mysql -h localhost -u root -p

and then when asked for the password I enter

 my_password

once again.

That works fine and I can access my database (called SampleDB) fine, and access all the tables, but I am having trouble turning this in to a C# connection string I can use with the SqlConnection object. If someone can provide me with the connection string based on the above credentials I would appreciate it greatly.

Many thanks

Answer 1

Because you’re first connecting with PuTTY to SSH into your server, and then running mysql commands while connected, it’s as if you’re physically sitting at the console of the server. In other words, you connected to your mysql instance using the address “localhost” because you are indeed already on that machine.

There’s two things you could do here to work around your problem:

1. Make an SSH tunnel in PuTTY, and connect to your MySQL
   instance through it.
2. Enable remote access in your MySQL server
   for connections from your desktop machine’s IP address.

Option one is more secure.
