Have a brand new OpenSuse 11.1 server, command line only setup.

I'm trying to get Trac installed and supposedly I can do this with yast so long as I add it's repository...

I Need to add the following repository to yast by URL but it keeps telling me it can add the repository. Is there something wrong with the URL I'm entering?

download.opensuse.org/repositories/devel:/tools:/scm/openSUSE_11.1/i586/

need to be able to install smartools and trac which should be available via the opensuse build services.

what have I got wrong here?
