How does who decide what data goes to ntpd and what goes to LH? If you have 2 serial ports, it would be easy to wire the pin from the TBolt to feed both serial ports. ntpd knows enough about TBolts to tell it to send the time every second. It would be easy to teach it to ignore stuff it doesn't want and doesn't already ignore. That would let LH drive things and ntpd would just listen in on the second port.

Re: [time-nuts] Tait reference
That's a very happy coincidence and one I'd hoped to hear. The pictures in the auction seem to show a lack of tarnish on the Ref Out and Ref In BNCs which suggests they have had plugs on them, looping the internal reference, other little bits of information also pointed to that, the remnants of a sticker on the front of one unit seems to say 'RUBID01...', past auctions of T801 units have been labelled with things like 'RUBID048', the hex switches seem to be set correctly for use with an internal reference as well so I was quietly confident they had the Rb option fitted. Now I just have to cross my fingers that mine arrive with the Rb in good conditon. The seller also states 'working order' so there's possible scope for a refund if it doesn't.

Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?
I’m going to guess “no,” because only one thing can connect to the ser2net socket at a time. If I were going to do it, what I might do is connect up the PPS output of the tbolt to a GPIO pin of the RPi and configure that pin for the pps device and set up ntpd for that. That way, LH can have the serial interface all to itself.

No, ntpd would be getting time from the serial port, not from the network socket. The idea would be that ntpd was getting the clock time from the serial port, but the time messages would be interleaved with whatever data the Thunderbolt was sending back in request to the LH commands. LH would also be seeing the time messages, but it sees those anyway, so I think the only concern would be the behavior of ntpd when all the data from LH commands is going by. Possibly a second concern of whether ntpd sends any commands to the Thunderbolt that might cause LH to be confused by responses to commands LH did not send. > If I were going to do it, what I might do is connect up the PPS output of > the tbolt to a GPIO pin of the RPi and configure that pin for the pps > device and set up ntpd for that. You still have to get wall clock time from somewhere, PPS just delineates the seconds, it doesn't name the seconds. For some cases you could have ntpd get the starting time from another network source and just use PPS to keep track of the seconds after that, but then you would still have corner cases of knowing when leap seconds occurred, maybe others. And of course if you relied on network access to other time servers you could not operate on an isolated network. > That way, LH can have the serial > interface all to itself. I've done this with a far more ordinary GPS > module to make a public stratum 1 server out of a Pi Zero for the NTP pool > (ntp.kfu.com). > How did it get the correct time set at startup? Did it have to query other network servers to set the time, then the PPS controlled the clock after that? Can it be a "stratum 1" server if it has to rely on another server to get the correct time when it starts up? I guess it could if it doesn't serve time until it has checked with other stratum 1 servers to make sure the time is correct. Sorry, didn't mean to go off into those weeds, but that isn't the system I want. I want a machine which can get the correct current time without reference to another system, which means that ntpd must get the time information from somewhere, either by directly reading the serial port, or passed through from gpsd which is reading the serial port, or some similar setup. The PPS driver would be connected directly to ntpd. -- Chris Caudle ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

If you telnet or nc into your rpi on port 3200, you should get a connection and you should get a bunch of garbage. If not, ser2net isn’t working. Is it running? sudo /etc/init.d/ser2net restart (did you do that after changing the config file?) If ser2net is working then it must be something about the LH params that’s incorrect.

Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?
Ed: A few recommendations for troubleshooting. In /etc/ser2net.conf comment out the 4 default lines (/dev/ttyS0-3) so that the line Nick provided is the only config present. Stop ser2net: /etc/init.d/ser2net stop then restart: /etc/init.d/ser2net start Make sure ser2net is running: ps -ef | grep ser2net If not, tail /var/log/syslog and see if any errors were reported on statrtup. Normally you just see a single line reporting successful startup. If it is running , make sure it is listening on the socket you specified (3200): netstat -tln | grep 3200 you should see a line with 0.0.0.0:3200 under local address There is additional troubleshooting you can do depending on results of above steps.
