If you see messages indicating that checkins are not taking place, the RHN client on your system is not successfully reaching Red Hat Network. Make certain:
- your client is configured correctly.
- your system can communicate with RHN via SSL (port 443). You may test this by running the following command from a shell prompt:
telnet xmlrpc.rhn.redhat.com 443
- the Red Hat Network Daemon is activated and running. You may ensure this by running the following commands:
chkconfig --level 345 rhnsd on
service rhnsd startIf these are correct and your systems still indicate they are not checking in, please contact our technical support team.
