subdomain quotas.

[geeknik]

I've seen people ask about this before, and no, you can't enforce a quota on a subdomain, but you can run this simple script once a day via crontab, and it will tell you if any of your subdomains are using more then they should be. =)

put this in your crontab(will run once a day @ midnight):

0 0 * * * php /home/username/public_html/subquota.php > /dev/null

It's good to see my script being put to use. :)

And just to let you know, I should be releasing a new version in a few weeks that will give you the ability to see all the users usages as graphs + lots of other features.

And just one more thing. If you use this script could you please send an email to me at ryan@gu-ru.net with the address of your website.
This is just so I can check out your site and see how many people are using the script.

Thanks for posting the script geeknik.

For everything to do with the script just remember to go here - http://www.gu-ru.net/scripts/subquota/

No problem. I like it, so why not advertise it. =)
