Resolution

  • If Red Hat Satellite server is behind HTTP proxy then confirm whether /etc/rhn/rhn.conf has proper entries for the same.

  • Confirm network connectivity to internet from RHN Satellite server.

  • Ensure satellite can pull updates from RHN as well as sync channels please open the access to the list of FQDN's mentioned below. For these FQDN's you need to open 80 & 443 ports (incoming and outgoing) are :

xmlrpc.rhn.redhat.com
satellite.rhn.redhat.com
content-xmlrpc.rhn.redhat.com
content-web.rhn.redhat.com
content-satellite.rhn.redhat.com
  • If it is not possible to open access to content-* fqdn mentioned above then disable Location aware update's for satellite server. Refer this article - How to disable location aware update

Diagnostic Steps

To check network connectivity :
ping satellite.rhn.redhat.com
telnet satellite.rhn.redhat.com 80
telnet satellite.rhn.redhat.com 443

To test that this is not a simple cache issue, let's have them do the following:

  • rm -rf /var/cache/rhn/satsync/*
  • satellite-sync
