If a computer was to come with high security, the same computer-iliterate sysadmin would hardly ever bother to open it. Niether would (s)he ever figure out how to export directories to clients. Or how to allow users to rsh from one client to another without a password. Or why ping won't run after cd /usr/etc (about . in $PATH). Of course, closed, "secure" system is easier to manage. But most computers are bought for users, not for managers :) And I bet that there are many sites where users would rather have insecure but functional system. After all, if you only have local area network and just several users \n is probably a good root password. Having said that I agree that it would be nice if manufacturies gave us some hints about how to make system more secure if needed (or perhaps even shell scripts to do the convertion). Oleg
