Basically, any NTP host whose sysadmin replies to your inquiry, saying "Sure, go ahead and sync to us". Or who has a public notice, e.g. on a Web page saying "Access policy: Open to the public" or such. > I don't want to have bad dreams about stratum 1 servers. They sound a > little scary. The problem inherent in them is that there are very few of them, and they're very popular: A stratum 1 server, by definition, is one directly connected to an atomic clock, and those just don't grow on trees. Stratum 2 means a machine that syncs to a stratum 1 server (which is so close to perfection that it really doesn't matter), and so on. Even stratum 4 or stratum 5 would probably be some ridiculously tiny fraction of a second different from perfect time-keeping. But because the stratum 1 and stratum 2 host lists are very easy to find, sync'ing to them strikes casual users as a good idea. I mean, they're stable, easy to find, and very, very accurate: Why not? At least, it seems that way until (as reportedly sometimes happens) they notice you and freeze out your IPs. It's sort of a "tragedy of the commons" type of problem. Anyhow, looking on the US, California portion of http://www.eecis.udel.edu/~mills/ntp/clock2.html (all stratum 2), I see: US CA ntp.ucsd.edu (132.239.254.49) Location: UCSD Academic Computing Services/Network Operations, San Diego, CA Access Policy: open access, please send a message to notify.

If I wanted maximally accurate sync, I'd include several such machines in my list. But really, the results are so close to perfect that it really doesn't matter that I could do better. -- Cheers, "Transported to a surreal landscape, a young girl kills the first Rick Moen woman she meets, and then teams up with three complete strangers [EMAIL PROTECTED] to kill again." -- Rick Polito's That TV Guy column, describing the movie _The Wizard of Oz_ _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
