Yum update not working from spacewalk server

Hello,
I have registered an SLES11SP1 server with my spacewalk server however when I perform a 'yum repolist', I do not see my spacewalk server as one of the available repositories. So when I perform yum update (any-package), it does not find an update available. HOwever within the Spacewalk GUI it can see that 23 packages have updates available. Can anyone shed some light on this?

Thanks,
Shaun

you need to have the satellite package from red hat with an active certificate to be able to use the spacewalk server to update your software (red hat) products ...

otherwise, find out what repo server spacewalk is looking at and try to add it to the repo list of your other servers ...

Thanks but that is not the problem. I already have CentOS servers registered and they are able to pull their updates from the Spacewalk server. I need to know why when I register a client to the spacewalk server, the client does not add the spacewalk server to the repolist.. see example below from a centOS server and the example from an SLES server.. Both servers are registered with the Spacewalk server however the SLES server does not show the spacewalk server as a possible repo.
