[time-nuts] Advice on NTP server needed

[Bob Camp]

Hi

The Net4501 servers I've made up have been very reliable boxes. They are low
power and simple to run. If you put an OCXO in them, their accuracy is as
good as it gets with NTP. The clock multiplier chip wiring can be a bit
exciting, that's the only crazy part.  

Cost wise, an Atom based machine / surplus PC would be similar. It won't be
as accurate or as low power. It might do more stuff for you. A lot depends
on exactly what you are doing.

Hello,

I have an upcoming need for a GPS disciplined NTP server in a low cost
project. Checking price
on commercial units shows that these are out of reach so I have been looking
into the possibility
of building an NTP server. I understand that the Soekris net4501 single
board computer is still
available and affordable timing GPS units shows up on Ebay regularly so I
assume these compnents
could be used. I have found a couple of reference to ntpns software on
internet, however I have
not been able to figure out the exact hardware configuration required for
this implementation.

Does anyone on the list have any experience putting together an NTP server
based on the net4501
running ntpns?

Any alternative ideas for inexpensive SBC based NTP server?

regards,

Per
