Hello, > What program do you use to ask the user somethnig? Are there any > other programs for this? I have built my own. It can be a simple program who ask "What's the birthday of my dog?" to a clock based key. The main purpose behind this program is to not drop the user to a shell prompt at first. What happens when a user logs in? Shell prompt. How do you know if the user who logs in is not a result of an automated attack? I mean, a result of a sucessfull brute force attack or easy guessable password? That's the idea. -- Regards, Alejandro Flores http://www.triforsec.com.br/
