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 Marek Grac 2015-03-09 12:03:01 UTC

Device HP iLO2 can be accessed over https, for this purpose we use gnutls-cli

With new firmware 2.27, SSLv3 was disabled by default. And previous configuration does not work anymore. In RHEL7 (gnutls 3.4), it is possible to use

--priority "NORMAL:-VERS-TLS1.2:-VERS-TLS1.1:+VERS-TLS1.0:%LATEST_RECORD_VERSION"

with this argument everything works as expected (thanks to Nikos).

Attempt to try this argument in RHEL6 failed because %LATEST_RECORD_VERSION is not supported. Omitting this argument;executing without --priority at all or adding "-VERS-SSL3.0" ends with 'Peer has closed the GNUTLS connection'. 

I agree that main problem is broken implementation on iLO2 side but I would like you to consider adding required option.

Comment 19 Marek Grac 2015-03-20 18:53:15 UTC

@Nikos:

sorry for bothering you, I have found out that issue was on my side.

gnutls_opts = "--priority \"NORMAL:-VERS-TLS1.2:-VERS-TLS1.1:+VERS-TLS1.0:-VERS-SSL3.0\""

works for us.

Thanks a lot, closing as not a bug.
