Chroot-BIND HOWTO

Scott Wunsch, scott at wunsch.org

This document describes installing the BIND 9 nameserver to run in a chroot jail and as a non-root user, to provide added security and minimise the potential effects of a security compromise. Note that this document has been updated for BIND 9; if you still run BIND 8, you want the Chroot-BIND8 HOWTO instead.
