As matter of fact I picked up a raspberrypi + gps receiver last week to start building a strat-1 ntp server for my network. My plan is to build 1-2 of these and use them to feed a couple of traditional servers that the rest of the equipment poll's.
This is what I ordered: https://smile.amazon.com/gp/product/B01C6EQNNK https://smile.amazon.com/gp/product/B010Q57SEE https://smile.amazon.com/gp/product/B00I6LZW4O Haven't had the time to actually put it together yet though, but there are plenty of resources available online on how to get it working. -----Original Message----- From: Af [mailto:af-boun...@afmug.com] On Behalf Of George Skorup Sent: Tuesday, September 05, 2017 9:19 PM To: af@afmug.com Subject: [AFMUG] GPS'd NTP I've got a few CentOS machines running around the network doing various tasks, one being NTP for radios, routers, switches, etc. I've been having some issues with us.pool.ntp.org lately. I switched to time-(a,b,c,d).nist.gov. Apparently those are pretty busy. So is anyone else using GPS to feed NTPd? From what I've been reading, I guess I need a 1PPS capable receiver. Does that exist in a simple USB package? That would be ideal, preferably with an SMA female for an external antenna where needed. Looks like none of the cheap shit I'm finding on Amazon has PPS output.
