Unless I'm mistaken, I believe that will actually run the script every hour on the hour. I think the correct syntax for daily at midnight would be:

0 0 * * * (nice -15 curl http://www.domain.com/subdir/maintenance/script.php)

I have logged into the server and if I run: (nice -15 curl http://mydomai.com/myscript.php) from root it runs perfectly. But if I switch to a regular user, it returns: "Permission denied" We did some hardening on this server according to DynamicNet's instructions, so I wonder if that is causing the cron not to run because of lack of proper permissions. What user does the HSphere cron tab use? to check if it has proper permissions. Also, what is the diference on using: (nice -15 curl http://mydomai.com/myscript.php) and using: curl http://mydomai.com/myscript.php > /dev/null 2>&1 Thanks a lot for your help.

Cron tab not running

I have followed instructions posted on this thread and still my cron tab does not run.

I have logged into the server and if I run:
(nice -15 curl http://mydomai.com/myscript.php)
from root it runs perfectly.

But if I switch to a regular user, it returns:
"Permission denied"

We did some hardening on this server according to DynamicNet's instructions, so I wonder if that is causing the cron not to run because of lack of proper permissions.

What user does the HSphere cron tab use? to check if it has proper permissions.

Also, what is the diference on using:

(nice -15 curl http://mydomai.com/myscript.php)

and using:

curl http://mydomai.com/myscript.php > /dev/null 2>&1

Thanks a lot for your help.

Rodrigo

Now what are you seeing the permission issues with , what user are you running this as and what are the permissions of the binary in question. ??

Hello,

Well in his case. I would bet that curl has permissions of 700 .. meaning it can only be executed as root. Now what are you seeing the permission issues with , what user are you running this as and what are the permissions of the binary in question. ??

dlst Registered User Join: Sep 2002 Posts: 168	I like the idea of NOT allowing curl to be executed by anyone except root. So, in this case, what's the "correct" way of running a php file via cron from the user's hsphere cp?

ladylinux Registered User Join: Jul 2003 Posts: 9,777	Hello, Ok .. so you want to allow a certain subset of users to be allowed to run the php binary ??? BTW .. this is not really the right place to be talking about Hsphere stuff ..
