Points of My Scenario:
1. I have an evaluation copy of Red Hat Linux 7.
2. I attempted to register it with the following command:
"[root@server1 ~]# subscription-manager register --username admin-example --password secret --auto-attach"
3. I am logged in as "root"
4. I repeatedly receive the error: "Network error. Unable to connect to server. Please see /var/log/rhsm/rhsm.log for more information"
5. The text at the end of this file (rhsm.log) reads "socket.getaddrinfo(self.host, self.port, 0, socket.SOCK_STREAM):gaierror: [Errno -2] Name or service not known"
QUESTION: How do I resolve this issue so that I can register my evaluation copy of Red Hat Linux 7?
Note that some utilities are not available without registration. I need to register Linux in order to properly study it! :-)
