(Shrug) While I'm far from an expert on NTP; I'm certain there are several people who read / post here who have similar setups. I didn't notice you mentioning which NTP version number you were using (it might make a difference). I did responded to a previous post of yours. Did you try (read up on) tos ... cohort? <http://www.eecis.udel.edu/~mills/ntp/html/miscopt.html> "tos ... cohort { 0 | 1 } Specify whether (1) or whether not (0) a server packet will be accepted for the same stratum as the client. The default is 0. " <http://www.eecis.udel.edu/~mills/ntp/html/manyopt.html> "Potential servers operating at the same stratum as the client will be avoided, unless the cohort option is present." Did you try (or read up on) server ... prefer? <http://www.eecis.udel.edu/~mills/ntp/html/confopt.html "Server Command Options ... prefer Mark the server as preferred. All other things being equal, this host will be chosen for synchronization among a set of correctly operating hosts." <http://www.eecis.udel.edu/~mills/ntp/html/prefer.html> See: "The prefer Peer" and "Mitigation Rules" Since you seemed to indicate just the GPS and one external stratum one server as sync sources, (and one of those often goes away?), increasing min sane (and min clock) doesn't seem like it would do you any good? -- E-Mail Sent to this address <[email protected]> will be added to the BlackLists. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
