I do think it's possible, as the PAM system has a pretty general idea of 'conversation' in its process of performing its actions. I even found a sample where someone implemented a CAPTCHA-style PAM quiz module that would ask you a series of simple math questions to ensure you weren't an automated script. It was really rough, but seemed to demonstrate that the idea could work. Getting a usable interface between the PAM module and the quiz-administering program could be tricky, but it seems very doable for someone with the inclination to do it. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
