Can you explain what the problem with a auth daemon is? If there was a daemon
listening on a system port then why couldn't local processes be sure that it
is the real thing (since its the same machine anyway - if a skript kiddie can
fake the daemon running on a system port then he has root anyway)? What am I
missing?
Thanks,
