Hello, I had a look on the list, but could not find simple straight forward explanation to spacewalk certificates and redhat channels Do I need to buy a satellite certificate from redhat in order to sync redhat channels? If yes, then: is there another way around syncing redhat channels considering I am using the open source version of satellite? Can someone provide the commands to do this please? At the moment I get this when I try to register: [root@eggers_new2 tmp]# rhn-satellite-activate --rhn-cert=space.signed.cert RHN_PARENT: satellite.rhn.redhat.com Error reported from RHN: <Fault 1024: 'Invalid Satellite Certificate'> NOTE: hosted RHN reports 'invalid_sat_certificate'.
