Just a follow-up on this thread. I created a test phpdig database so I could mess with this a little more without clobbering production. Tried to populate the test database initially from shell, and phpdig wouldn't index any pages at all. My saved spider log was totally empty, too. I checked my server log, and nothing shows up for phpdig at all there.
I went ahead and populated my test database using the secure web page, and although it took about 3.5 hours to spider, it still indexed everything I would have expected. So why doesn't it work from shell?
Just now, I tried to update the index via shell, and the same thing happened that did initially - nothing indexed, empty spider log, nothing in the server log.
When I type uptime from the shell, here's what I get:
up 18 days, 38 minutes, 2 users, load average: 0.11, 0.31, 0.33
Any suggestions as to where I go from here? I've hit a brick wall...
