Oops, thanks for the catch. That was typo that carried over from earlier from another master. Should be all better now. $ hostname; ls -l /etc/localtime balug-sf-lug-v2.balug.org lrwxrwxrwx 1 root root 27 Apr 19 09:56 /etc/localtime -> /usr/share/zoneinfo/Etc/UTC $ cat /etc/cron.d/local-bind-master-auto-rcs 0 10 * * * root exec >>/dev/null 2>&1 && cd /etc/bind/master && for zone in e.9.1.0.5.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa berkeleylug.com sf-lug.com sflug.com sf-lug.net sflug.net balug.org berkeleylug.org sf-lug.org sflug.org; do rndc sync -clean "$zone" && rndc freeze "$zone" && { rcsdiff "$zone" || { rcsdiffrc="$?"; [ "$rcsdiffrc" -ne 1 ] || { ci -l -d -M -m'checking in change(s)' "$zone"; }; }; rndc thaw "$zone"; }; done; : $ > From: Al > Subject: Re: [BALUG-Admin] BALUG VM, dynamic DNS & (automatic) > version control (added) > Date: Mon, 20 Apr 2020 06:23:32 -0700 > digtitalwitness.org ? > > is that a typo? >> $ cat /etc/cron.d/local-bind-master-auto-rcs >> 0 10 * * * root exec >>/dev/null 2>&1 && for zone in >> e.9.1.0.5.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa berkeleylug.com sf-lug.com >> sflug.com sf-lug.net sflug.net balug.org berkeleylug.org sf-lug.org >> sflug.org; do rndc sync -clean "$zone" && rndc freeze "$zone" && { >> rcsdiff digtitalwitness.org || { rcsdiffrc="$?"; [ "$rcsdiffrc" -ne >> 1 ] || { ci -l -d -M -m'checking in change(s)' "$zone"; }; }; rndc >> thaw "$zone"; }; done; : >> $

Doesn't catch the "why", and doesn't catch change-by-change, but automatic daily check-in of any changes, "good enough" for my(/our?) purposes here, and have that now: $ cat /etc/cron.d/local-bind-master-auto-rcs 0 10 * * * root exec >>/dev/null 2>&1 && for zone in e.9.1.0.5.0.f.1.0.7.4.0.1.0.0.2.ip6.arpa berkeleylug.com sf-lug.com sflug.com sf-lug.net sflug.net balug.org berkeleylug.org sf-lug.org sflug.org; do rndc sync -clean "$zone" && rndc freeze "$zone" && { rcsdiff digtitalwitness.org || { rcsdiffrc="$?"; [ "$rcsdiffrc" -ne 1 ] || { ci -l -d -M -m'checking in change(s)' "$zone"; }; }; rndc thaw "$zone"; }; done; : $ hostname balug-sf-lug-v2.balug.org $ ls -l /etc/localtime lrwxrwxrwx 1 root root 27 Apr 19 09:56 /etc/localtime -> /usr/share/zoneinfo/Etc/UTC $

BALUG VM Debian oldstable --> stable
by Michael Paoli 19 Apr '20

19 Apr '20

Okay, one more time ... hopefully relatively smoothly this time. Have done fair bit more thorough testing, essentially on "cloned" virtual machines (while also taking the appropriate precautions to avoid conflicts with the running production). Anyway, will restart the upgrade process soon. If all goes relatively smoothly, should be complete after a few hours or so. Services - for the most part will mostly remain up and operational throughout, but there will definitely be at least some disruptions, due to some required reboot(s) and stopping and restarting of services. I'll update once things have completed and things look good ... or any substantially different results. This BALUG VM is the host that supports essentially all (except some additional DNS slaves) services of: BALUG and likewise excepting list services, for: SF-LUG BerkeleyLUG references/excerpts: https://lists.balug.org/pipermail/balug-admin/2020-February/001017.html https://lists.balug.org/pipermail/balug-admin/2020-February/001018.html http://linuxmafia.com/pipermail/conspire/2020-April/010521.html http://linuxmafia.com/pipermail/conspire/2020-April/010525.html
