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 of problem:
The Network UPS Tool (NUT) wants to notify users when something critical happens. It uses wall for local users but fails when one of them is on 'seat0' since there is no /dev/seat0.
Version-Release number of selected component (if applicable):
util-linux-2.32.1-42.el8.x86_64
How reproducible:
100%
Steps to Reproduce:
1. login to graphical console so loginctl says you are on seat0
2. echo "test" | wall
3. view error
Actual results:
; loginctl
SESSION UID USER SEAT TTY
2 1001 lvd seat0 tty2
1 sessions listed.
; echo test | wall
wall: /dev/seat0: No such file or directory
Expected results:
"test" appears on all local terminals including xterms
Additional info:
Fixed (wall(1)) in the upstream tree by commit 7d3713a6d541be0bac0bb78cc8fea1620583fd08.
write(1) seems OK, it works on demand for the specified user and it prints an error when not able to get usable tty.
