 Posted: Sat Sep 29, 2007 4:48 am Post subject: Help, I can't edit my crontab anymore! |
 |
|
I recently did an emerge -avDu world (after not doing one for about two months). I normally use 'crontab -e' to edit my crontab. As root it seems to work fine, but as non root I get the error:
| Code: |
cannot chdir(/var/spool/cron), bailing out.
/var/spool/cron: Permission denied
|
Has anyone else had this problem? What is the best way to fix it?
Thank you for your time,
Arrummzen |

Hello there,
Don't worry about it, just see if /var/spool/cron exists and if not create it. Then change the permissions to cron:root and 755 for the directory.
Then check for a dir /var/spool/cron/crontabs and if it does not exist create it with permissions root:crontab and 1730 (yes 1730 not 730 )
Last check for directory /var/spool/lastrun with permissions root:root and 750
That should do the job. |

| Or you could update to the latest sys-process/cronbase which should do the same for you ... |

Which, FYI, doesn't work at all. Re-emerging cronbase or not doesn't apply the correct permissions. You have to do it manually or revert to an older, working version.
Many thanks to Kosmas for the nice "how-to"... took me about an hour to figure it out, heh. |

| Some of my users on the server i run have had this problem and reported it as an error on a number of occasions. After looking in to it, i finally found that it was simply the question of adding the user to the cron group. It dose seem to work fine after that, thou they need to run crontab -e first sometimes. P.S. incase you're wondering the default for my server is to just have an empty cron.deny file in /etc/ to allow all users in the cron group to use the crontab. I've read the documents on the crontab but i dont plan on changing it any time soon. vixie-cron version 4.1-r10 USE="pam -debug (-selinux)" |

So...
This still isn't fixed.
I had to create /var/spool/lastrun to get it working. Is there even a bug submitted for this? Anyone know how I could check?

| Do you mean /var/spool/cron/lastrun? Did you add yourself to the crontab group after emerging cronbase? |

No /var/spool/cron/lastrun existed after emerging cronbase and vixie-cron
I did add myself to the cron group as well as the crontab group, logged out and logged back in... no go...
not until I added /var/spool/lastrun did it start working.
I have no idea why honestly... if it helps im running a gentoo-hardened profile.

I found I simply had to | Code: | | # chmod o+rx /var/spool/cron |
and things started working.

| I tried all the above solutions nothing worked, so I installed fcron and removed vixie-cron and now works.. fine and it's even a more flexible vixie-cron replacement. |

There's definitely a bug, at least here on am64.
Follow Kosmas' instructions, except that /var/spool/cron ownership is root:cron, not cron:root.
No need for anyone to be in the cron group. |

I have some issues with cron:
(current title, but I am uncertain what it is)
The new cronbase' issues with grsec RBAC policy
https://forums.gentoo.org/viewtopic-t-1026832.html
(again, I'm uncertain where my issues will end at, but they concern cron)
These issues appear to span in long years...
Any more on this? Such as is it still the case to fix those permissions in some of the fashions proposed in this topic? |

This issue is, I think solved in all new cronbase packages...
But if anyone has issues deploying RBAC policy for their grsec-hardened kernel, you can look over:
crontab RBAC policy
