Open Port 3306 for MySQL connection
I am needing to "un-block" port 3306 so that I can access MySQL from another PC.
When I installed Mandrake 8.1, I set the security level to high because it is going to be a web server. I believe I have to allow access to my ports now and I do not know the commands to do that.
If anyone could show me an example, that would be great.
