I'm trying to setup a crontab specifically for the user that runs the web process. I have root/sudo access so I wrote an entry for the www-data user using the -e option and here is the listing using the -l option:
/etc$ sudo crontab -u www-data -l # m h dom mon dow command 15,30,45 * * * * /var/www/cron/test.cli.php
The process is not running at the appointed interval however. I'm pretty sure I have the syntax correct so this leads me to a few other possibilities
1) improperly formatted /etc/cron.allow? I actually created this as sudo/root and all I've done is enter a line with "www-data" on it. However, is this the correct format? I'm having a hard time finding information on how /etc/cron.allow should be formatted, its not in the man as far as I can tell (http://linux.die.net/man/1/crontab)
2) Is /etc the correct location for cron.allow on Debian? I googled and it mentions that it might go elsewhere under SUSE but all indications unless I'm mistaken is that under Debian /etc is the correct location.
3) Permissions for /etc/cron.allow? I (temporarily) set them to 777, could this be too permissive?
4) Does cron need to be restarted after the creation/modification of cron.allow (or cron.deny)?
PS....since first posting this on stackoverflow (where I will now delete it) I have tried restarting cron to no avail: the task still does not run
