Is the following URL where your spider.php file is?
Code:
http://www.john-howe.com/admin/spider.php
Seems to be like it should be:
Code:
/[PHPDIG-directory]/admin/spider.php
That's probably where your 404 is coming from. Note the relative script path, and that it may not work that way. I ended up having to do mine like this:
Code:
/home/username/public_html/[PHPDIG-directory]/admin/spider.php
So your whole command should probably look like this:
Code:
php -f /home/username/public_html/[PHPDIG-directory]/admin/spider.php http://www.john-howe.com/
Check out the
phpdig documentation for more details on the command line interface.
