Cronjob not longer working in SUSE 11.0

Hi all,

are there any changes in cron behaviour on SUSE 11.0?
I’ve created a cronjob-file for a daily update process under
/etc/cron.d

Code:

30 20 * * * root zypper up -y -t patch --skip-interactive

Well, the cronjob doesn’t run on SUSE 11.0 (worked fine since SUSE 9).
Are there any changes?

Thanks in advance,
Andreas

Check cron is really running - just in case.

I had a similar problem a few months ago. I did a Web search and recall
seeing some posts complaining that /etc/cron.d didn’t work like it used
to.

I solved my problem by moving my cron job into a crontab in
/var/spool/cron/tabs. Simply create a file with the appropriate username
(in your case, root) and put the job in there. Remove the “root”
username spec from the job (it’s implied by the name of the file when
you run from a spool/tab).

Swerdna has an excellent how-to on using the crontabs. You can see the
minor differences by following his advice.

‘HowTo: Cron Tables (Crontab) to Schedule Events in Suse Linux
(openSUSE) 10.x, 11.x’ (http://www.swerdna.net.au/linhowtocron.html)

If that doesn’t work, then as the previous poster suggested, ensure the
cron itself is running: execute “server cron status” as root in a
terminal, or use Yast -> System -> Services (Runlevels).

Hmm, /etc/cron.d has worked fine for me under 11.0 and now 11.1.

If you look in /var/log/messages, there should be a line at the time it
tries to execute the job.

Thanks for all your answers!

Well, the cron deamon is running fine, but /var/log/message/doesn’t
list the update job.
I’m using the /etc/crontab file for custom time/user configurations for
some of the jobs. All these entries are executed normally. I’ve included
the update command in this file, we’ll see the results tomorrow…

I wonder why are there so many possibilities to run cronjobs:

  1. files in cron.daily, cron.hourly, …
  2. files in cron.d
  3. crontab -e
  4. /etc/crontab

The only interesting difference is the one-file-per-user scenario with
crontab -e

Seems to me a bit confusing…

In the beginning there were two locations, per user using crontab -e and
the system crontab /etc/crontab.

/etc/cron.d is a logical extension of /etc/crontab. It allows packages
to easily put and remove custom crontabs there without having to disturb
the master crontab. It’s also a good place to put app specific crontabs,
you can group a bunch of actions which might be run by different
accounts, for say moodle.

/etc/cron.{hourly,daily,weekly,monthly} are actually caused from that
initial entry in /etc/crontab which says /usr/lib/cron/run-crons

I know. It SHOULD work. But like andi303, it wouldn’t work in my case.
Don’t know why and I can’t explain it.

But the fix is simple: just move it to a per-user crontab file in
/var/spool, and it seems to work. Go figure.

Did you remember that crontabs in /etc/cron.d require the account name
in the 6th field?

Yep, and if you look at andi303’s post, it’s done that way. I tried it
that way, too.

Maybe it just hated me.
