orphan mode is about a group of computers. "Orphan Mode allows a group of ntpd processes to automonously select a leader in the event that all real time sources become unreachable (i.e. are inaccessible)." chrony's is that you can enter the time by hand (Ie, by typing a current time and hitting enter) on a single machine. You are the "remote clock". Now, how useful that is now adays is open to question, but in the past with telephone modems and flaky connections it was worth something. And if you are setting up something on the Hebrides or on a buoy in the Atlantic where no connection of anykind is possible, it could be useful. Ie, it IS different from orphan mode. > _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
