--- Begin Message ---Package: ntpdate Version: 1:4.2.2.p4+dfsg-2 Hi, /etc/network/if-up.d/ntpdate runs even if you bring up a virtual interface like eth0:5; I don't see any reason why it should ever do that. Please fix this. TIA. (I see little reason for it to run by default on the bringing up of eth0, but that's another matter.) -- 2. That which causes joy or happiness.

--- Begin Message ---Version: 1:4.2.8p12+dfsg-2 Dear user, the bug you have submitted is related to the ifupdown triggers shipped by the ntpdate package that did a one-shot time sync every time an interface managed by ifupdown was configured. The hooks have been removed from the ntpdate package in version 1:4.2.8p12+dfsg-2, which will be part of the Buster release. ntpdate.NEWS reads: TL;DR: The ntpdate package does NOT ship triggers for ifupdown to run a one-time sync every time an interface comes up anymore. These hooks will also be removed on upgrades to Buster. It is strongly recommended to switch to a permanent NTP daemon like ntp, systemd-timesyncd or chrony. If you need a one-time sync in your setup please arrange for it yourselves, i.e. by calling sntp with the appropriate parameters in /etc/network/interfaces(.d) . Historically the package ntpdate has included both /usr/bin/ntpdate (which is the historic go-to program for one-shot NTP querying) and ifupdown hooks to execute a one-shot NTP query on every interface up event. The ifupdown hooks have introduced buggy behaviour by syncing too often (on every ifup), too seldom (never again) and are likely to interfere with other time-keeping measures on the same system including ntpd. The hooks frequently caused dependency problems with local DNS resolvers or uncommon network configurations. They have therefor been dropped from the ntpdate package. For time synchronisation purpose please use one of the many timekeeping daemons in Debian (ntp, systemd-timesyncd, chrony). For the manual use, /usr/bin/ntpdate has been deprecated upstream and replaced by /usr/bin/sntp (in the sntp binary package). If you want a proper one-shot sync against a pool of servers you may also consider the -q option of ntpd. Best Regards, The NTP maintainers
