UNIX for Dummies Questions & Answers

I've got a little php app that I'm trying to call from a crontab entry that's not working. The entry looks like this:

55 * * * * curl -m 600 --connect-timeout 120 http://www.mysite.com/ad_renewal.php

When I run curl from the command line, it works fine and I get an email saying so. However, from within cron, it doesn't go. I tried a little echo line that wrote hello to a file and that worked fine so I think I'm doing OK with my cron properties.

Strange. Maybe there's some security restriction on curl? Not sure what it could be.

Oh, yeah, originally, only had curl url and I added the other options thinking that it might be timing out or something. The process does take about 45 seconds to run.

provide the absolute path for curl

also redirect STDOUT and STDERR to a file, so that it would be easier for debugging
