[ntp:questions] Garmin 18x LVC - two dead units this year
Not really a question any more than "Is anyone else having this much trouble with Garmin 18x?" I ordered a Garmin in early January, got it running by 1/29/09 Garmin device died 3/13/09 New replacement installed 3/27/09 Second unit died this afternoon. Bummer. Guess I will have to keep one spare on hand.

Re: [ntp:questions] Quoting Practices (Was: Re: Test internal clock)
I love the passion that people feel for the computing industry in general, and two of my favorite topics in particular: smtp and ntp. I am a relative newbie to usenet, having only been participating since 1987. I have heard the top-post, bottom-post, and how to quote discussion many times in the past 20 years. I didn't used to care much about it; I can figure out the message well enough either way. In the last couple years though, I have come to have an opinion and feel compelled to share it only as food for thought. I truly hope to not offend anyone, just enlighten! I now use a handheld for both regular 8-5 work and my personal business. One is a blackberry, the other a treo. I can keep up with all my business while I travel, so that I don't have as much to catch up on when I am back in the office. Well quoted, top-posted messages are the easiest for me to deal with on a handheld. I submit that as time goes by, the old conventions will need to change a little as more and more people work from a handheld. I can swallow either top or bottom post, really, but have great appreciation for a well-quoted message that I don't have to scroll up and down in to follow the quoting. In-line quoting is the worst to handle because line wraps are not pretty on a handheld. Thanks for listening, and for all the excellent content provided in this forum.

[ntp:questions] Learnings: FC8 Linux ntpd syncs to NMEA message but not PPS
I have now managed, with the patient help from Bill U., to get my Linux NTP system running using the PPS signal from a Garmin 18x LVC. I thought I would share what I had to do to make it all work. * References: http://time.qnan.org/ http://time.qnan.org/shmpps.tar http://www.david-taylor.myby.co.uk/ntp/FreeBSD-GPS-PPS.htm http://fixunix.com/ntp/67883-freebsd-garmin-gps-18-lvc.html * What's it running on - Dell Optiplex 740 running Fedora Core 8 - ntpd 4.2.4p2 - Garmin 18x LVC, powered off USB port, communicating on /dev/ttyS0 * - I built the circuit as shown on the time.qnan.org site. - I tried to use gpsd but that didn't work. I got NMEA to work but not PPS. - I tried shmpps but it didn't work either, so I started digging deeper. - Bill U. sent me a change to add to the shm_spl2.c file which would tell me if the driver was "seeing" data from my GPS. Nope. - I checked my circuit board over and over, no problems seen there. - I finally checked the cable that I had between the circuit board and the NTP server - crap, there was no connection between PIN 1! Turns out only seven of the nine pins had connections through my cable. Weird - I made my own cable with crimp on terminators and some ribbon cable. - Check it out, PPS data! * NOTABLES: - Don't blindly trust your cable! Just because it works for some things doesn't mean it will work for you here. As Bill noted, lots of serial cables are made with only pins 2 and 3 in mind to be concerned about - Watch your syslog file! It will tell you interesting things like "ntpd can't find /dev/gps0" - so you get to add a symbolic link between /dev/ttyXX to /dev/gps0. - If you have NMEA output from the GPS in your ntp.conf file (127.127.20.0), expect it to have "reach 0" reported when you finally get PPS (127.127.28.0) working. You can have NMEA or PPS from your serial input, you just can't have both at the same time from the same GPS on the same port. - With that said, be sure to have a remotely well clocked device to do an initial synch to before starting the shmpps driver. (See start.sh and shmpps scripts in ths shmpps tar file.) - See my circuit board here: http://www.toosan.com/shared/gps * CONTENTS of ntp.conf driftfile /var/lib/ntp/drift statistics clockstats loopstats peerstats statsdir /var/log/ntp/ filegen peerstats file peers type day link enable filegen loopstats file loops type day link enable server 127.127.20.0 server ntp.wendysi.com iburst server 127.127.28.0 minpoll 4 prefer fudge 127.127.28.0 refid PPS flag3 1 * OUTPUT FROM ntpq -p remote refid st t when poll reach delay offset jitter == GPS_NMEA(0) .GPS.0 l- 6400.0000.000 0.001 10.255.213.232 10.255.231.148 2 u 63 64 3770.1732.336 0.398 *SHM(0) .PPS.0 l6 16 3770.0000.005 0.002 * DEBUG output from shm_spl2 (shmpps) range:4-11 sys:1233259966/84 ref:1233259967/0 prec: -17 range:0-7 sys:1233259980/83 ref:1233259981/0 prec: -17 range:2-9 sys:1233259994/84 ref:1233259995/0 prec: -16 range:3-10 sys:1233260008/83 ref:1233260009/0 prec: -16 ___ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
Re: [ntp:questions] ntpd syncs to NMEA message but not PPS
Well, I've managed to wind myself completely up in my huggies I built a nice little 18x LVC setup this weekend, based on the circuit at time.qnan,org. I successfully get data from the GPS (9600 baud) and a PPS signal. I tried using the gpsd driver and am having no luck with it whatsoever. So, I have to ask at this point, what exactly did you mean "just use the shmpps set of routines to set up pps using the shm refclock"?

Re: [ntp:questions] ntp peer association in VLAN query
Danny - It sounds like this is the same behavior that I asked about a few weeks ago, I think. I have a Windows machine with two IP addresses, acting as an NTP time source for devices on one of the two networks. Time synch requests come in from the clients on network A, and the response from the Windows machine is out the interface on network B.

NTP will see that it does not match the going address and will discard the message. That's correct behavior. You need to figure out why the packet is coming back with the incorrect address. i suspect the VLAN but I cannot be sure.
