Link checker modules fails to detect a test broken link I downloaded, installed, enabled and configured the linkchecker module.  When I run it from the Drupal interface, it seems to be checking but I don't see in the report a test link (within ) that I have purposefully misspelled. This test link is to an external site.  Does it matter for the link checker module if my development site is not publicly accessible-- I think it is accessible only from campus.

Linkchecker version 6.x-2.7; drupal-6.26
Found Link checker works after  'run cron'

That a cron job has to be run after the configuring.
--  I had already set for automatic running of cron job.  For some reason it didn't work.
--  It worked after running cron job manually.
site-url/cron.php for D5 and D6

-- OR For Drupal 6.x, see in your site: Administer > Reports > Status report > Cron maintenance tasks > Run cron manually.  

Steps for checking links:


Make sure link checker configuration is what you want  
http://site-url/cron.php  in browser to run cron job (it yields blank page after the run)  
See report for broken links and follow up specific links.
