It's generally considered rude for an "average user" to synch to any ntp server without permission. But there are plenty of stratum 1 servers available which have an open access policy. To quote http://www.eecis.udel.edu/~mills/ntp/servers.html: The list of primary (stratum 1) and secondary (stratum 2) designates the NTP time servers available for public access under stated restrictions. ... It is very important that potential clients avoid use of servers not listed as open access, unless approved first by the responsible person. This especially includes indiscriminate use of servers not listed in the list, since this can be disruptive. Note that this also implies that Dan's idea of finding the closest server, apart from bringing no advantage, is also considered inappropriate. > To answer the other question, ntp stands for "Network Time Protocol" > and is also a generic label to apply to the servers, clients, etc. The > xntpd server supports version 3 of the protocol, ntpd is version 4.
