RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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.

Description Alicja Kario 2015-06-23 16:09:08 UTC
Description of problem:
It's not possible to enable DHE cipher suites when using mod_nss

Version-Release number of selected component (if applicable):
all

How reproducible:
Always

Steps to Reproduce:
1. Configure mod_nss with all ciphers supported
2. Connect with openssl s_client -cipher EDH
3.

Actual results:
connection rejected

Expected results:
Connection established

Additional info:
Server side DHE support in NSS is implemented: https://bugzilla.mozilla.org/show_bug.cgi?id=102794

mod_nss should also provide the option to enable the weak, 1024 bit DH parameters, as well as the option to select one of the bigger groups, not only the 2048 bit default.

Comment 3 Matthew Harmsen 2016-01-05 22:19:27 UTC
Per discussion with rcritten, moving from RHEL 7.3 --> RHEL 7.4.

(support DH ciphers)
