Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Command user to update the certificates:

satellite-installer --scenario=satellite --verbose --certs-update-server --certs-update-server-ca --certs-server-cert sat6certA.example.com.cer --certs-server-cert-req sat6certA.example.com.req --certs-server-key sat6certA.example.com.key --certs-server-ca-cert sat6certA.example.com.ca-bundle


Fragement from the production.log that shows that the proxy wants to communciates, but fails because certifictes changed

Comment 1 Stephen Benjamin 2016-10-13 15:27:09 UTC 
Created redmine issue http://projects.theforeman.org/issues/16906 from this bug
Comment 3 Peter Vreman 2016-10-14 08:15:39 UTC 
The root cause was that we got a certificate with a private key of 16384 bits. This large private key is not supported by the smart proxy.

Reproduction:
1. Create a private key of 16384 bits
openssl genrsa -out $(hostname -f).key 16384
2. Createa and Sign the certificate
3. Configure Satellite 6 to use the custom certificate
Comment 5 Bryan Kearney 2018-09-04 17:45:42 UTC 
Thank you for your interest in Satellite 6. We have evaluated this request, and we do not expect this to be implemented in the product in the foreseeable future. We are therefore closing this out as WONTFIX. If you have any concerns about this, please feel free to contact Rich Jerrido or Bryan Kearney. Thank you.
