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.

Comment 2 Vojtech Polasek 2022-02-21 10:06:07 UTC 
Hello,
thank you for the BZ. The rule OVAL check has two parts which are connected with conjunction:
1. It checks for the correct snippet in either /etc/bashrc or /etc/profile.d/*. I guess this part passes after remediation.
2. It checks if a tmux process is running. I guess this part fails. This will be probably always reported as "error" because the Tmux process will just not get started. Someone has to log in so that their shell sources the particular snippet and starts tmux.
Two questions:
1. do you have tmux package installed?
2. Does the rule pass if you reboot and perform the scan again?
I am not sure if this has any simple fix because of the nature of checks.
Comment 3 Jan Pazdziora 2022-02-21 10:48:54 UTC 
1. No, tmux is not installed.
2. No, it does not pass after reboot either.

I must ask: why should tmux be running? It gets started when a user logs in ... why does compliance check (which might be run from a cron job for all we know) care if there is a user logged in or not?
