[SATLUG] Mysterious cron problem

[Sean Carolan]

I have a simple script running as a cronjob on a desktop workstation.
The workstation has Ubuntu 7.04 with the standard version of cron.
Here's how the crontab entry looks:

*/5 * * * * /usr/local/bin/myscript

That worked fine and dandy.  However when I try to run the exact same
script on my laptop the cronjob does not execute at all.

I can run the script from the command line on the laptop and it works
great.  I can also run any cron jobs as root.  But as soon as I try to
add even a simple entry to my regular user's crontab file, such as
this:

* * * * *  echo "Hello world"

I get nothing.  I've tried to turn on logging and watch the logs for
anything suspicious but nothing shows up there.  It's like cron just
completely ignores my user's crontab file altogether.  I don't have
/etc/cron.d/cron.allow or cron.deny files either.

Any ideas?  I'm stumped.
