I am located near Frankfurt, so the distance should not be the problem. Even in the basement I can receive the DCF77 signal. I played around with the fudge time1 parameter. At the moment I have it set to
server 127.127.8.0 mode 19 fudge 127.127.8.0 time1 0.009 But until now I could not find a good value. Thanks for all of your help and your suggestions. Regards _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
