Ah, nice idea. I never considered that one. The disadvantage to this approach is that if one of your users finds a local exploit and becomes root inside her chroot() jail, she could then overwrite the programs linked from her $HOME/bin -- which are the same programs that ALL your users are using. So suddenly every chroot() user would be running the trojan programs. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
