One of our customers has 6 GPS-locked NTP servers. Only problem is that two of them are reporting a time that is exactly one second different to the other four. You shouldn't rely solely on your GPS or DCF receiver - use it as the primary source but have some secondary sources for sanity checks. (From experience, I can state that ntpd does not behave well when presented with two stratum 1 servers that differ by 1 second). --=20 Peter Jeremy --N1GIdlSm9i+YlY4t Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGRMrl/opHv/APuIcRAtaZAKCCfRk4mT+V1EhaWcRJ71XwiqoPEgCeKEUx 7ndWvid/WPI3iFSo7tdNomI= =8VNC -----END PGP SIGNATURE----- --N1GIdlSm9i+YlY4t--
