3.4. Troubleshooting

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 start
    If these are correct and your systems still indicate they are not checking in, please contact our technical support team.
