No unread replies. 3 3 replies.

We live in an environment where there are hackers always attempting to get access to our server’s data and configuration. One of the ways to prevent that is by using the DNS jail or chroot. It is a pseudo root that users cannot get any higher in the directory structure.

The tasks of the administrator is to make sure these services that are installed and configured properly so they are not compromised.
