At work, we have a requirement for a warning banner to be displayed and accepted prior to user authentication. I see that we can display an arbitrary message at the beginning of a session (after authentication) with NodeLoginGreeting and NodeFirstLoginGreeting, but this doesn’t quite accomplish what we need. The UserScript* directives in server.cfg and node.cfg look tantalizing, but there doesn’t appear to be a way to pass a warning banner before authentication occurs.
Has anyone accomplished what we’re working on?
We’re running NoMachine Workstation 5.1.40 on RHEL 7.2, using SSH authentication only. We want warning banners to display irrespective of how clients connect.
