Resolved Setting up cron job

Thank you, rolandd.

The path was incorrect, but I found a path to php where I got an answer:

root@vps [/]# /usr/bin/php -v

PHP 5.4.45 (cgi-fcgi) (built: Sep 27 2015 12:06:37)

But though the cron job is run, it still does not produce any output.

Oct 31 06:00:01 vps CROND[24019]: (xxxuserxxx) CMD (/usr/bin/php /home/xxxuserxxx/public_html/administrator/components/com_csvi/helper/cron.php --key="######" --template_id="5")

(from the cron log).

The cron job is run as the user (masked) so there shouldn't be any permissions problems for writing the output, I believe. When I run the export from Joomla backend, it does produce the output file, according to the settings. Thus the template seems OK, but somewhere around the call to the helper/cron.php things don't go as they should. The path to cron.php is correct, tested with ls /home/....../cron.php.

Hello,

Is this the correct path/folder? How would I recognize the "php executable"?

I don't administer your system, so I don't know which is the correct path, your hosting provider should know.

You can test this by doing

/usr/local/lib/php -v

as it gets you the PHP version. If that is a new version it should be good enough to be used.

The secret key, I believe is the one specified on the tab "Details" just beneath the setting "Enable front-end/cron", isn't it?

Correct, that was a typo and I have fixed it now. It is the secret key field in your template.

Thank you for the answer, rolandd. Now I wonder, what exactly should there be in the folder for the php executable? A listing for the one I used is:
root@vps [/usr/local/lib/php]# ls
./ .channels/ .depdblock .filemap pearcmd.php Structures/ XML/
../ Console/ doc/ .lock PEAR.php System.php
Archive/ data/ docs/ OS/ peclcmd.php test/
build/ .depdb extensions/ PEAR/ .registry/ tests/
root@vps [/usr/local/lib/php]#
Is this the correct path/folder? How would I recognize the "php executable"?

Another question, same subject: In the instructions for building the cron command there is a line saying "The password belonging to the supplied username.". Where do I supply a username, and what username should it be? The username for Joomla, or for the server - or which? The secret key, I believe is the one specified on the tab "Details" just beneath the setting "Enable front-end/cron", isn't it?

Assuming that the path to the PHP executable is correct, it looks good. You have set in your template to allow cron usage?

I believe that the destination file should be the one in my template settings?

Correct, that is the destination you set on the Source tab.
