Re: Adding Node to RAC Fails with SSH Equivalency on NxN Check

Morning Mladen and Ghassen,

I can ssh to node3 from node3 as both the oracle and grid users. I DO have a message that pops up when I ssh to node3 as any user:

*grid node3:/home/grid $ ssh node3Activate the web console with: systemctl enable --now cockpit.socketThis system is not registered to Red Hat Insights. See https://cloud.redhat.com/ <https://cloud.redhat.com/>To register this system, run: insights-client --registerLast login: Wed Apr 13 09:04:41 2022 from 192.168.194.133-bash: [: =: unary operator expected*

Looking around to see where this might be scripted.

Any assistance in tracking this down would be helpful. I suppose I could just register the system with Red Hat Insights and enable the cockpit, but the less that the server does, the fewer points of attack there might be, the easier they might be to spot and the happier I am.
