I know it's a long time, but I'm cleaning up old NTP bugs atm. Robie asked the right question back in 2012. I checked todays status.
The issues still applies to Xenial as well as Debian. So maybe whatever was the reason for the removal back then no more applies? I reported it to Debian as it is not Ubuntu specific. So for tracking adding https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=822961 ** Bug watch added: Debian Bug tracker #822961 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=822961 ** Also affects: ntp via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=822961 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/1046340 Title: ntp package missing logcheck exceptions file /etc/logcheck/ignore.d.server/ntp Status in NTP: Unknown Status in ntp package in Ubuntu: Confirmed Bug description: Hello, in Lucid, Package: ntp (1:4.2.4p8+dfsg-1ubuntu2) has the file /etc/logcheck/ignore.d.server/ntp included. This is used to configure logcheck to ignore ntp messages in syslog that are not error conditions. However: In Natty, this file is not present in the ntp package In Oneric, this file is not present in the ntp package In Precise, this file is not present in the ntp package When logcheck is installed, all ntp syslog messages are raised as alerts by logcheck because the ntp configuration file is not present. It would be helpful to have /etc/logcheck/ignore.d.server/ntp included with ntp packaging as with Lucid. Here are sample contents based on the Lucid version with the addition of "status change" tot he time sync line. ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: time reset [+-]*[0-9]{1,2}\.[0-9]{6} s$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: synchronisation lost$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: no servers reachable$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: synchronized to ([0-9.]{7,15}|[0-9a-fA-F:.]{4,39}), stratum [0-9]+$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: synchronized to LOCAL\([0-9]+\), stratum [0-9]+$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: kernel time sync (disabled|enabled|status change) [0-9]+$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: precision = [0-9]+\.[0-9]+ usec$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: peer ([.0-9]{7,15}|[0-9a-fA-F:.]{4,39}) now (in)?valid$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: adjusting local clock by -?[.0-9]+s$ ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ntpd\[[0-9]+\]: adjust time server -?[.0-9]+ offset$ Regards, Tim Miller Dyck ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: ntp 1:4.2.6.p3+dfsg-1ubuntu3.1 ProcVersionSignature: Ubuntu 3.2.0-29.46-generic 3.2.24 Uname: Linux 3.2.0-29-generic x86_64 ApportVersion: 2.0.1-0ubuntu12 Architecture: amd64 Date: Wed Sep 5 10:09:31 2012 InstallationMedia: Ubuntu-Server 11.04 "Natty Narwhal" - Release amd64 (20110426) KernLog: Sep 5 06:34:04 cmpsVMHost01 kernel: [271957.578288] SGI XFS with ACLs, security attributes, realtime, large block/inode numbers, no debug enabled ProcEnviron: LANGUAGE=en_CA:en TERM=linux LANG=en_CA.UTF-8 SHELL=/bin/bash SourcePackage: ntp UpgradeStatus: Upgraded to precise on 2012-08-25 (10 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ntp/+bug/1046340/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
