Hi, we have discovered that most of the off campus sources we had for our NTP service are no longer there. Anybody willing to let us connect to their servers? -- Russell Fulton /~\ The ASCII Network Security Officer \ / Ribbon Campaign The University of Auckland X Against HTML New Zealand / \ Email!
Check out http://www.eecis.udel.edu/~mills/ntp/clock2a.html
and look for "nz"

Setting up a GPS NTP source has been on the list of things I've wanted to get done for a while now - I've got several rooftop mounted PC's that have stunning views of the heavens. If anybody has any recommendations on a reasonably priced GPS based NTP appliance, or even what serial GPS unit I should buy to interface simply with ISC NTP, then I'm all ears. Cheers Si

Dick Smiths have a usb GPS receiver ( http://www.dse.co.nz & search for XH6831 ) which uses the standard NMEA protocol over what seems to be an emulated serial port. ntpd should be able to make use use this with its own internal drivers. At $234 its cheap enough for almost anyone to setup a stratum-1 server, and DSE offer quite good support for Linux users. I've got a Garmin Etrex receiver and data cable, but I just haven't had the spare time to connect it into an ntp server. Kerry

A good GPS unit for timing is Trimble's Acutime 2000, which is a dedicated timing GPS receiver that runs in 'overdetermined clock mode', i.e. it assumes it is stationary. http://www.trimble.com/acutime2000.html Their starter kit has all you need, bit pricy tho. If you want an appliance Truetime are the most popular, there's also EndRun Technologies, http://www.endruntechnologies.com/time-servers.htm. Note that although their CDMA units used to work in NZ, they mysteriously stopped a year or more ago, you should stick to GPS. Presumably Telecom changed something in the 027 network.

Hi Russell,
we have discovered that most of the off campus sources we had for our NTP service are no longer there. Anybody willing to let us connect to their servers?
Does anybody know what has happened to bigben.clix.net.nz? We're now using msltime.irl.cri.nz and ntp0.cs.mu.oz.au, with bigben.clix.net.nz still in the list until I hear whether or not it's coming back. There must be a *lot* of NTP configs out there that depend on bigben as a stratum 1 NTP server... -- don

bigben.clix.net.nz was a Trutime GPS receiver that we bought before I left CLEAR, and which was installed in various places after I left by other people (it was on Level 48 in the Sky Tower for a while, but I think it moved out of there after a while). I heard a rumour the other day that it has not been demonstrating a high degree of happiness with the query load presented to it, and there was some plan afoot to drop a sub-stratum ntpd box in front of it to hide the Trutime box from the public query load. I didn't hear that from anybody at TCL, though, so that might not be right. Joe
