After running

Yum install "desktop" which I understood would install and use the gnome desktop, I get the following error when running yum install <anything>.

any ideas?

You need to register your system with the Red Hat Network

You need to have a valid username and password

--C

Thanks for they input.

I had already setup a connection to an LSU redhat satellite. It was working for the last couple months until I did the yum install "desktop" and it started producing that error.

When I try to register with LSU (they use probably a hybrid of rhn_register named rhnreg_ks.

I would normally do

rhnreg_ks --force --ServerURL https://LSUserveraddress.lsu.edu/XMLRPC --sslCACERT /pathToTheCertFile --username user --password password

When I do this, it says a Username, password and CSI are required to register the system.

The documentation from LSU does not specify a CSI being required.

Any ideas on where to go next?
