1. mk

   still breaking my head over how to find out what (if anything) happened to my cron jobs; finally http://bencane.com/2011/11/02/did-my-cronjob-run/ gave me a clue: Hal (ASUSTOR NAS) has /etc/rsyslog.conf which has the line '#cron.* -/…

     @mk the problem with /etc/rsyslog.conf is of course that it's under the system root, thus loaded from flash memory at boot time - so any changes will be completely wiped out on reboot :(

     @mk Is there any way (that you know of) to change it in the flash, so your (updated) files will be copied onto the system at boot time?

     @lnxw48 no, none that I know of (and I dug around a lot in the forum); the only way for some changes seems to be to store them in the /volume0 or /volume1 branches and copy scripts over at boot time - via cron, which is what I'm now trying to debug ;-) #catch22

     @mk yay! I FINALLY managed to get (busybox...) crond to log to a log file; though setting the log level via '-l N' does not seem to be supported (but there may be a workaround for that via '-d N'). So now I know that a) the updatedb …

     @mk I'm also finding lots of confusion all over the pkace becaue there are many different versions of cron which support (do not support) different features - never mind if they are mentioned in the man page. Hard to know how to write a crontab file that way! #ugh

     @mk ...and slowly, slowly, am I getting this nice #NAS box called Hal a bit more under control. Lots of riddles and #frustrations today, but also #learning, #discoveries, and #progress. In all, a good day (in spite of seemingly havin…

     @mk This morning, with more entries in the cron log (and even the system log) I'm starting to notice some odd patterns... 1) after ONE manual ntpdate update 23:24 , I am seeing THREE updates about an hour later (all at the same time …

     @mk what's also odd is that this second cron can not have been started with the same command-line parameters I gave the first one - but it's logging to the cron log anyway. ??? #evenmoreconfuzzled

     @mk ...and in the process list on ADM I see THREE crond's running (that would explain the three ntpdate updates, but not why they stopped again after that)

     @mk as I now found out, when I STOP crond, it gets automatically restarted moments later. WTH is doing that? (Anyway, no need for a 'restart' option in the (boot) startup script...). What is worse is that sometimes it's started even …

     The messages log gave a clue: a process called 'watchmand' "relaunches" crond - no idea why because so far it's been doing this twice while crond was already running...

     @mk and I cannot find anything anywhere about 'crontab_check' (except that it's apparently NOT part of BusyBox). Asking it for its help only produces an error message that it's already running.
