It is customary to _not_ sync from a stratum 1 server unless a large number of other machines are syncing from you, and then to get permission. It is also generally polite to get permission / inform stratum 2 servers if you plan to use them. Also, if you are just using ntpdate to sync, and not xntpd, using a stratum 1 server is kinda silly. Find a few nice stratum 2 and 3 servers and sync from them. A nice list can be found at ftp.udel.edu somewhere in /pub/ntp -- it might be in the xntpd distribution itself. Lots of nice stratum 2 servers to sync to. -Craig
