How to allow a user to use cron?

dictum9 — Mon, 23 Jan 2006 08:50:48 GMT

How does one authorize a regular noon-root user to use cron, so he can schedule jobs?

Does it have something to do with permissions, or the group file?

From "man crontab":

"You can execute crontab if your name appears in the file /usr/lib/cron/cron.allow. If that file does not exist, you can use crontab if your name does not appear in the file /usr/lib/cron/cron.deny. If only cron.deny exists and is empty, all users can use crontab. If neither file exists, only the root user can use crontab."

Hi,

Put the name of the user in the file /var/adm/cron/cron.allow
after that the user can make is own cron file.

But he can't schedule root jobs in his cron.
only jobs he can execute himself.

Hi,

You will have a asccii file called cron.allow which is located under /var/adm/cron. Simply add the user to this and they will be able to created cron jobs.

Hi etc,

Edit /var/adm/cron/cron.allow, add your user there.

Also, take your time to assign points to the people who spent time and responded to your question.

Hi,
An example from my /var/adm/cron/cron.allow
file;
baan01:/#cat /var/adm/cron/cron.allow
root
adm
uucp
rvs
baycom
ae1820

so my extra users like rvs,baycom,ae1820
can handle their own cron jobs!!!

Hope this helps you!!!

Good Luck,

Ps:Please Do not forget to submit points!

Do I need to restart the cron process? (i.e. kill -HUP pid)

Thanks, and I will submit points.

Hi:

No, you do not need to restart 'cron' after editting the 'cron.allow' or 'cron.deny' files.

You may also want to setup the same user's in 'at.allow' and 'at.deny' at you do for cron. It is often very convienent for a user to first test with 'at'. See the manpages for 'at(1)' for more information.

Hi,

Edit /var/adm/cron/crontab.allow a insert new user. Example:

# cat /var/adm/cron/crontab.allow
root
user1

Next, create crontab file for "user1"

# crontab -e user1

and insert commands.

Verify,

# cat /var/spool/cron/crontabs/user1

When you enter user name in /usr/lib/cron/cron.allow, user is able to use crontab. Or If you are having a file of /usr/lib/cron/cron.deny without any entry then all users are allowed.

No need for restarting cron service. It will lookup those files during crontab execution only.
