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. One fix for this is: sudo dnf remove 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.
