Granted, let's say 'pool oriented' then, because that feature would be much more helpful for pool users. Let's face it, for other users, it is quite seldom that an ntp server keeps the same domain name while switching to a new IP. Also, I have seen secure environments that don't even have DNS access so they are configured with IPs or hostnames in /etc/hosts, our 'pool oriented' solution wouldn't help much. -Louis > > Rob > _______________________________________________ > timekeepers mailing list > [email protected] > https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers > Louis _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
