Crontab Codeigniter 403

[eluser]christeso[/eluser]
I'm trying to run some crons and am getting 403 errors.

I've tried following several tutorials such as this one http://codeigniter.com/wiki/Category:Adv...ronScript/ and this one that states 2.02 can be run from cli http://ellislab.com/codeigniter/user-gui...l/cli.html

Neither have worked for me. I've tried both calling server files directly from crontab and also wget and curl both from Plesk and CLI.

Can someone fill me in on the best method to call a controller via crontab?

Thanks,
Chris
