I'm having troubles with my crontable on the scientific cluster I'm using. It's a bit peculiar, since the jobs seem to run (I get regular mails from some updates) but when I type

crontab -l

the response is:

>     no crontab for USER

Same story for

crontab -e

where I end up with an unedited file, somewhere in the tmp folder. So my question is: Where could this crontab possibly be? I checked some "standard" places, but it seems that there is nothing.

Any ideas, anybody?

Best, L.

    /etc/crontab, /etc/cron.d, /etc/cron.daily, etc – Boban P. Mar 21 '16 at 12:40

    Someone else's cron job could be emailing you – Jeff Schaller Mar 21 '16 at 13:04

    Then you shoudl analyze mail headers, look at the Received headers, and you will definatly find out where did mail come from. – Boban P. Mar 21 '16 at 15:46

    The job is presumably set up on some other machine in the cluster. @BobanP. You should write that up as an answer, I think that's as good as it gets. – Gilles 'SO- stop being evil' Mar 21 '16 at 22:37

First of all, there is good possibility that mails are coming from somewhere else, so you need to make sure where did it come from. Inspect mail headers, particularly Received: headers. It will show you that info.

  • That helped as a first step, I found that some backup-server kicked in. I wrote an email to the IT guys, since I can't log in this server. Maybe this will do it. Thanks a lot ;) – rammelmueller Mar 22 '16 at 8:00
