- Red Hat Enterprise Linux
Hi, I'm pretty new to Redhat and trying to get a Redhat Enterprise 7.2 system configured in VMWare Workstation 12.5.4 running on a Windows Server 2008 R2 SP1.
I've got the base install done, am connected via ssh, and am trying to connect to Subscription Manager.
This is the error I receive:
[root@servername pki]# subscription-manager register
Registering to: subscription.rhn.redhat.com:443/subscription
Unable to verify server's identity: certificate verify failed
If I run the openssl test, I receive this:
[root@servername ~]# openssl s_client -connect subscription.rhm.redhat.com:443 -CAfile /etc/rhsm/ca/redhat-uep.pem
getaddrinfo: No address associated with hostname
We suspect the issue might be packet inspection by the firewall.
We have a Checkpoint firewall with web url filtering enabled and a self-signed cert that we need to add to IE/Firefox on Windows systems to get through the packet inspection on the firewall. I'm trying to figure out how I would add that same firewall self-signed cert on a Redhat system to enable packet inspection and allow it to talk to the Subscription Manager.
Does anyone else have any experience with this?
