We are using the xntpd among the two hosts on our class C with the firewall
acting as a server to both hostsi, the router allows the firewall access to
our class C net, so we needed to use the firewall as a server. The firewall
itself is using the kerberos master server as the xntpd master server. It is
absolutely essential for the system clocks to be in sync for kerberos to
operate. If not then the tickets issued will be out of sync and not operate
or better yet expire (at least for 5 minute root instance tickets).
Marcus is right they make good clocks. We are using the xntpd in just the
fashion that marcus describes.
