Hello again! First I want to thank all respondents on the list for a number of advices to my questions although it is not exactly 'time-nuts' stuff!
I have now decided to monitor eBay for commercial units for some days in a hope to find a unit in an reasonable priceclass (and a seller willing to ship overseas). If I do not find a unit in an relative short timeframe I will pursue the net4501 idea. The reason for this is mostly based on the installation environment. I am 'piggy-backing' on an commerical site (ie. for free) and rack-space and electricity are premium. I have also a need to have the installation look professional in order to avoid to much 'bad' attention. The installation already occupies a 3U receiver, 1U server plus a 1U GPRS modem, so using an old PC for NTP server is out of the question. Also the additional 2600 kWh per year electricity (150W x2 for PC plus cooling) would strain my goodwill at the site. As for Internet, yes we do have an connection, but via GPRS so it is not any good for ntp use. As for performance I am seeing 200-400 ms today with GPRS which is not good enough for my application, I hope to get down into low or sub ms range.

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 _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. ----- No virus found in this message.
