Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.
The build is: RHEL-8.0-20181220.1, when login by ssh:
# ssh xxx.xxx.xxx.xxx
root.xxx.xxx's password:
Activate the web console with: systemctl enable --now cockpit.socket
Last login: Mon Jan 7 14:52:39 2019 from 10.72.12.156
What's up with that? I've never seen this additional output before.
This happens on purpose, and explains how to either enable or access (depending on the state) the web console (aka Cockpit). It's a more dynamic variant of the static /etc/issue message that Fedora Server showed.
Sometimes, if I run some command line in the Terminal, this strange message still output and the command line will return non-zero status, even the cockpit.socket status is running.
Any workaround?
# virsh dominfo 7.4_Server_x86_64 | grep '^Name'
Activate the web console with: systemctl enable --now cockpit.socket
# echo $?
254
Re-opening since this breaks automation methods like 'expect' scripts. If you do actually enable the socket, then the message changes to:
Web console: https://FQDN:9090/ or https://IP:9090/
There is also a Fedora equivalent bug 1635200 requesting to stop these messages.
Please provide a method to disable the messages.
Removing (or commenting out) the pam_motd.so module from /etc/pam.d/sshd is one method to stop the messages, although it seems like a rather blunt tool.
One can also remove the /etc/issue.d/cockpit.issue and /etc/motd.d/cockpit symlinks, but this is temporary since they will return with the next update to cockpit-ws.

The correct way to disable it is "ln -sfn /dev/null /etc/motd.d/cockpit", so that the next cockpit-ws package upgrade doesn't bring back the file.
This is already documented in pam_motd(8) in Fedora 31, in pam-1.3.1-18.fc31:
To silence a message, a symbolic link with target /dev/null may be placed in /etc/motd.d with the same filename as the message to be silenced. Example:
Creating a symbolic link as follows silences /usr/lib/motd.d/my_motd.
ln -s /dev/null /etc/motd.d/my_motd
Unfortunately this part of the manpage is not yet in RHEL 8.2 (pam-1.3.1-5.el8). It should be, so I'm reassigning to PAM.
