Years ago,
I had configured a system to prevent a user from logging into a system via telnet, but I can't remember now how I did it. Right after the motd was displayed, another banner would show up saying this is a closed system and shortly thereafter, they were logged out.
Does anyone know how to accomplish this. I'm looking through my notes but can't seem to recall.
I always "/sbin/chkconfig telnet off" which stops all connections to the telnet port. It's a Good Thing(tm).
I suspect your notes refer to /etc/nologin which I always used to do years ago to prevent undesirables from logging into the system while I was doing things with it. I believe -- and I really check I suppose -- that the pam_nologin module handles this.
