I have not yet tried the ntp part, but LadyHeather 3.00 Beta (running under Wine) connects. With tboltd -v, I get a lot of unknown packets. I'll separately send mail to Ralph with the output, for validation. For gpsdclient, I haven't figured out where to get the bedec16 routines for Linux. There's /usr/include/bits/endian.h but it doesn't contain them. There's mention of a freebsd man pages package which documents them, but no idea where the actual routines are or what package they are in.

Re: [time-nuts] Lady Heather Daemon for FreeBSD
Hi Sounds *very* useful. Which version(s) of FreeBSD have you tried it on? Thanks! Bob -Original Message- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] On Behalf Of Ralph Smith Sent: Tuesday, February 02, 2010 12:41 PM To: time-nuts@febo.com Subject: [time-nuts] Lady Heather Daemon for FreeBSD I have written a small daemon that attaches to a Thunderbolt and acts as a client for Lady Heather. In addition, if specified it will provide data to NTP through the shared memory driver. It currently compiles on FreeBSD, and OS X. Available at http://ralphsmith.org/~ralph/thunderbolt.tar.gz It is in a very early, rough stage at the moment, but I thought I would provide it for anyone that is interested. There are two programs: tboltd, and gpsdclient. First tboltd: Usage: tboltd [-t tty] [-v] [-p port] [-u unit] [-d] -t tty: Specify Thunderbolt serial port. Default 'cuau1'. -v:Increase verbosity level. -p port: UDP port to listen for client connections. Default 45000. -u unit: Unit number for NTP shared memory driver. Default to none -d:Do not detach and run in daemon mode. Some notes: - tboltd will currently accept as many clients as memory allows. - tboltd currently does not buffer requests from clients. Multiple clients risk having commands interleaved. - Logging needs to be implemented properly - tboltd blocks when there is no activity on the thunderbolt or client. On a Net4501 (133 MHz 486 equivalent), with 3 clients (1 Heather + 2 gpsdclient) it takes less than 1% CPU. - Likely to be bugs. - I invoke it on my Net4501 as tboltd -p 45000 -t cuau1 -u 0 - Corresponding ntp.conf entry # Use shared memory tos mindist 0.030 server 127.127.28.0 minpoll 4 maxpoll 4 prefer fudge 127.127.28.0 time1 0.0275 refid GPS Second: gpsdclient. gpsdclient will attach to tboltd or gpsd, receive Thunderbold TSIP packets, and drive an NTP shared memory segment. Usage: ./gpsdclient [-g] [-u unit] [-p port] host - The -g flag will sent the command to gpsd to put it in super-raw mode to deliver TSIP - Currently not configured to detach and run as a daemon, will fix that when I get around to it. This needs some cleanup and reorganization, but I thought some of you might be interested.

Re: [time-nuts] Lady Heather Daemon for FreeBSD
Hi I'm running 8 on most of my stuff now, so that should not be an issue. If you had come back with 6.1 that might have been reason to stop and think a bit. Does the program take care of all the serial line setup stuff, or are there links and stuff that need to be done to get it to talk right? Some of the NTP serial drivers seem to require a bit of a massage on the serial settings to make them happy.

Bob Nothing special required, it just blindly goes with the Thunderbolt's default configuration of 9600 8N1, and configures the serial line accordingly.
