I've been trying for the past couple of weeks to set up an ntp server syncing with chu using the audio drivers. I got sound set up on the computer that I'm using (an old dell GX110) using the open sound drivers from http://www.opensound.com/
I have a Kaito KA1103 that I tuned to CHU on 3330 kHz. I ran the audio signal out of the radio from the line out port, through an audio isolation transformer into the line in port on the Dell. When I plug a set of headphones into the line out port on the computer, I can hear the audio clearly. However, ntp never seems to sync using the audio signal. I changed to WWV audio drivers and set the radio to listen to WWV at 10 MHz to see if I could get it to sync to that, and it doesn't. I'm using the stock kernel in lenny with the stock install of ntp from apt-get. Below are my config files and settings: If there are any other settings that you want to see, please let me know. /etc/ntp.conf # /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help driftfile /var/lib/ntp/ntp.drift # Enable this if you want statistics to be logged. statsdir /var/log/ntpstats/ statistics loopstats peerstats clockstats filegen loopstats file loopstats type day enable filegen peerstats file peerstats type day enable filegen clockstats file clockstats type day enable #server 127.127.7.0 #fudge 127.127.7.0 flag2 1 flag4 1 time1 0.0005366 stratum 1 server 127.127.36.0 version 4 fudge 127.127.36.0 time1 0.007532 flag2 1 stratum 1 # Local users may interrogate the ntp server more closely. restrict 127.0.0.1 restrict ::1 # Clients from this (example!) subnet have unlimited access, but only if # cryptographically authenticated. #restrict 192.168.123.0 mask 255.255.255.0 notrust /etc/ntp.audio0 idev /dev/dsp cdev /dev/mixer source line agc line monitor line ntpq -c cl assID=0 status=0101 clk_noreply, last_clk_noreply, device="WWV/H Audio Demodulator/Decoder", timecode=, poll=197, noreply=197, badformat=0, baddata=0, fudgetime1=7.532, stratum=1, refid=, flags=2 ntpdc -c kerninfo pll offset: 0 s pll frequency: 0.000 ppm maximum error: 6.35652 s estimated error: 1.6e-05 s status: 0040 unsync pll time constant: 4 precision: 1e-06 s frequency tolerance: 500 ppm ntpdc -c loopinfo offset: 0.000000 s frequency: 0.000 ppm poll adjust: 0 watchdog timer: 12743 s aumix -q (mixer settings) vol 72, 72, P pcm 92, 92 speaker 0, 0 line 84, 84, P mic 96, 96, R cd 0, 0, P igain 75, 75 line1 4, 4, P phin 0, 0, P phout 75, 75, P video 0, 0, P monitor 0, 0 There are no entries in /var/log/ntpstats /var/log/syslog, when I restart ntp Nov 24 07:58:21 time ntpd[2195]: ntpd exiting on signal 15 Nov 24 07:58:24 time ntpd[2487]: ntpd [EMAIL PROTECTED] Wed Jul 16 12:11:41 UTC 2008 (1) Nov 24 07:58:24 time ntpd[2488]: precision = 1.000 usec Nov 24 07:58:24 time ntpd[2488]: Listening on interface #0 wildcard, 0.0.0.0#123 Disabled Nov 24 07:58:24 time ntpd[2488]: Listening on interface #1 wildcard, ::#123 Disabled Nov 24 07:58:24 time ntpd[2488]: Listening on interface #2 lo, ::1#123 Enabled Nov 24 07:58:24 time ntpd[2488]: Listening on interface #3 lo, 127.0.0.1#123 Enabled Nov 24 07:58:24 time ntpd[2488]: kernel time sync status 0040 Nov 24 07:58:24 time ntpd[2488]: frequency initialized 0.000 PPM from / var/lib/ntp/ntp.drift Thank you, Court _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
