Hello everybody, With ntp 4.2.4, I strangely get a very slow display of the ntp -p billboard. Example:
| $ ntpq -p | remote refid st t when poll reach delay offset jitter | ============================================================================== | SHM(0) .DCF. 0 l - 64 0 0.000 0.000 0.004 | *LOCAL(0) .LOCL. 8 l 60 64 377 0.000 0.000 0.004 This takes more than a minute to display, line by line. A named querylog shows that it's due to DNS resolver delays until timeout. It seems that when showing a refid, ntpq does a DNS A request on the name "DCF.<localdomain>", gets immediatly a "does not exist" authoritative answer. Then it does an A request on "DCF" alone, without answer until timeout. Then only ntpq displays the line and ".DCF." with the added dots around. The same happens for other refids LOCL, INIT, and such. However when the refid is an ntp server, it's displayed as dotted quad immediatly, without delay. Now I have 2 questions: - Why does ntpq request A on refids? I remember the good old reverse PTR resolution long ago when refids were IPv4s. But why an A? - What's broken on my system so that not qualified hostnames are not considered local (my named forwards those A requests to my provider's servers)? Thankfully, Serge. -- Serge point Bets arobase laposte point net _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
