Crontab does't seems to work

[peterg]

I'm a new in linux and stuf..............
My problem is, when I run cacti/cmd.php in my webbrowser, so the graphic updates. But when crontab updates it, nothing hapends.......

Remove the redirection from the crontab entry. That is, cut out the "> /dev/null 2>&1", and then check root's email after 5 minutes. You'll get to see any error messages that may have been generated.

Chances are that your crontab isn't including the path correctly to the CLI php. Try changing the crontab entry to include the path to php. Type which php at your command line and use that as the result.

e.g. which php
/usr/bin/php

crontab now reads /usr/bin/php /cacti/cmd.php > /dev/null ... etc.

When I deleted "> /dev/null......", I get this message from webmin when I run the crontab (this is the same message when I run cmd.php in linux):

Output from command /usr/bin/php4 /usr/share/cacti/cmd.php ..

I have a feeling that the config.php file doesn't have the correct username and/or password for the database and I'm not sure if anything else is missing.

I think you don't have de mysql extension enable in you php.ini...
Add a line in you php.ini such as :
extension=mysql.so
