 |
|
Hey Folks,
ive got a strange problem. I'm running Gentoo on a virtual server where it has been isntalled and now i can use it as rootserver. It works pretty well but i've got a cron problem.
No matter wether the jobs are in users crontab (crontab -e) or in /etc/cron.[daily|weekly|...]/ by the time when a job should run i get permission denied in syslog and thats it. For example:
| Quote: | Aug 3 11:30:01 vtux cron[17384]: Permission denied
Aug 3 11:35:01 vtux cron[17390]: Permission denied |
(vtux 's the name of the box)
Anybody any suggestion? I've got a cron-user, a cron group, everything seems allright. I've emerged vixie-cron(vixie-cron-4.1-r7) several times. nothing helped at all...

That is fine. Its running the way it should.
What are the settings in /etc/pam.d/cron ?
I hope there is no line
| Code: |
account sufficient pam_deny.so
auth sufficient pam_deny.so |
Better still, can you post the output of the file here?
Also what are the directory/file settings inside /var/spool/cron ?
You haven't used chattr here have you?

chattr? Not that i know of. I might have used chmod or chown in a humbly strike to solve the problem on my own...

Is it wrong or right? Should the cron user/group be involved somewhere there?

I use vixie-cron and can't see any difference between your set-up and mine. Can you clarify whether this affects all crontabs? Or does it work for root and fail for users??

Checked this on a couple of mine and both the same.
I notice your logs don't give the name of the user for the crontab. Mine do, but I can't find anything to help solve.
I'd be tempted to unmerge, nuke every file and directory for Cron and start again. |

| Code: | # /etc/init.d/vixie-cron stop
...
# rc-update del vixie-cron
...
# userdel cron
# groupdel cron
# rm -r /etc/cron*
# rm -r /var/spool/cron*
# groupadd cron
# useradd -g cron cron
# emerge vixie-cron
...
# rc-update add vixie-cron default
...
# /etc/init.d/vixie-cron start
... |
That seems to do the trick...

| It's a bit of a sledgehammer approach but there was no clear trace of anything wrong, it just didn't work. Glad it worked out. |
