I've compiled ntpd with shared memory support and trying to get it to talk to gpsd using a really basic ntp.conf file
server 127.127.28.0 minpoll 4
fudge 127.127.28.0 refid NMEA
I can telnet into gpsd and see it query the nmea messages, but if I start up ntpd and gpsd, then gpsd just sits there. Based on my ntp.conf file and gpsd startup is there anything else I should be doing?
