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?
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.
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
