Trackback always seems to fail

It seems no matter what site I link to, Serendipity fails to enter a trackback to that site. I always get the error 'No trackback URI found' even though the page contains a trackback URI. What exactly is Serendipity looking for? How do I troubleshoot this? Is there any logging that can be turned on?
I'm running Serendipity 1.0, PHP 5.1.4-pl0-gentoo, apache-1.3.34.

Do you link to a s9y-blog, too?
The problem: When a blog has a text like "this is my trackback-uri" this is only for humans. Try to add this link in the trackback-plugin, it should work.
The other thing: There is a way to see the trackback-uri by a maschine. s9y can read thuch uri's - but many blogs out there do not have such a maschine-readable uri in the html-source-code; s9y has such a code:
It is a so-called RDF-information:
Code: Select all

That's part of the problem. I have tried pasting that into the trackback plugin and it still doesn't work. It appears to load that page looking for the RDF info rather than using it to post a trackback.

The first one worked. Plugging the second one into the trackback plugin resulted in:
• Checking
http://mein-test.supersized.org/comment ... ntry_id=29 for possible trackbacks...
• Trackback failed: No trackback-URI found.

hm,
Code: Select all
• Überprüfe http://mein-test.supersized.org/comment.php?type=trackback&entry_id=29 auf mögliche Trackbacks...
Sende Trackback zu URI http://mein-test.supersized.org/comment.php?type=trackback&entry_id=29...
• Trackback erfolgreich

I just upgraded to the latest - 1.0.1 - and get the same results on the manual trackback entry.

I just went to the Serendipity download site and noticed the trackback-control plugin is currently at version 1.16. My system had 1.5. I upgraded and it appears to work now. Guess that one doesn't get updated with a Serendipity update....

Yes, there are only a few plugins with the core installation. Most of them are downloadable from spartacus and must be updated the same way.
But with the new s9y-version you have two buttons on the top of the plugin-page to see the new plugin versions.
