Locking the screen from login terminal
So I've got this home file server, and I want to display certain stuff using:
a tcpdump of snort logs, scrolling in real time
I want it to display on the screen using a split terminal screen, so all of the information shows on one display, but I do not want it to be vulnerable to a local attacker. Is there any way I can have these things start up at login, but prevent that user from doing anything other than viewing this information?
I'm thinking maybe a chroot jail? Any ideas?
