Can anyone point me to the proper documentation for getting a Redhat NTP daemon to synchronize it's time reference from a Debian NTP daemon. I just installed a Redhat 9 server (only because I had to) on our network of primarily Debian (Stable) servers. It was easy enough to configure Debian to synchronize from two "internal" masters which themselves sync with selected NTP stratum 2 servers. The "ntpservers" file originally listed Redhat as the master reference, but changing this to use our internal servers reports no valid servers found.
