The documentation of sage says this.
You have a Linux Server (Operating system:openSUSE 11.1 + Plesk 9.5) not a windows Server Thus the technical specifications for the Sage Line 50 are not met and cannot be installed on the Server you have.

You're referring to hosting, not connecting. You will need a Windows server.
