   I have a question to the general community. I see a fair number of trackback/pingback issues. As I understand, there is a known problem with this feature, which began in v2.0. I myself am unable to send trackbacks or pingbacks (I can receive fine).

   I've searched high and low for a posted solution or workaround, but I've not found any. I have found a number of posts, but they do not conclude resolving the issue.

   Also, please do not take this as a 'troll', but when I see others post this issue, it's treated as if it's a new problem or that it must be something with the users setup / ISP. I've read a ton of posts back from the 1.5 > 2.0 transition, that seems to substantiate there is a legitimate bug. Again, I'm sure there's a solution or at least an acknowledged bug report. If someone could post the link I would be very appreciative.

   I've only been messing with a test blog for now, pending getting trackbacks to work. Then, I want to wipe and start up a production blog.

   Thanks in advance for any good links you can provide. Also, I'll post system and config info upon request.

   Test to and from here:
   http://www.tamba2.org.uk/wordpress/TestTrack

   I know of no bug. There are hosts with problems maybe but there is no bug as such.

   Is there anyone on your host that uses WP?

   Hi podz,

   I've seen you around here a bit, thx for the quick reply. :-)

   Well funny enough, a current search of "trackback" in Documentation, Support Forums, WP.org Blogs and the Bug Database, returns nothing. I'm sure I saw some threads previously in the Bug Database.

   Anyway, I host my own server. Apache on Fedora. I'm at work now, so specifics would have to wait.

   Thx for the tamba2.org.uk/wordpress/TestTrack link. I've used that to verify I can receive trackbacks and pingbacks successfully.

   There are people with problems I'm sure.

   Part of the problem ( and I'm not suggesting this about you) is that some people are unaware of how exactly to send pings and tracks, some send both so the track fails and some genuinely do have a problem. Additionally some people delete pings and tracks from their blogs, others cannot receive if they are on other hosts or are protected against overly happy trackback spam stoppers. So .... mix all that up and that's why we get a lot of posts at times and also why looking for a solution is tricky.
   It was one of the reasons I set up the TestTrack blog - I know it sends and receives so the problem cannot lie with it (though some people forget to check moderation there).

   But if you can't send, do post back with stats and hopefully someone who better understands what code is used will be able to advise.

   To send trackbacks, all you *should* need to do is to link to a page that can receive them. Namely, link to a post's permalink on somebody else's blog in one of your own posts.

   That's a ping for a wp blog though?

   Otto42,

   You're referring to pingbacks correct? Using tamba2.org.uk/wordpress/TestTrack, I've created my own posts. Then placed the 'Trackback URI' into the trackback entry field in a new post on my blog (no link within the body of the text). Hit publish. Upon re-entering edit mode, the trackback URI is still in the trackback field. My WordPress has not processed it. I've also tried pingbacks (links within the body of my text), with no trackback. This has had no results as well.

   This leads me to believe there's a issue with the php code somewhere (maybe) no flames pls. ;-)

   podz,

   I found a couple of the threads that eluded to a bug issue since 2.0. Take a look.

    javajunkee, you say you created a post at Podz's test site, then added the trackback link in a post on your site. What are you expecting to happen? did you check the posts on Podz's site to see if it received your trackback? (there are 12 posts in moderation, though I can't access them).
    Your site won't do anything. And the trackback address stays in the field as far as I remember. (I tend to only use pingbacks these days).

    Hi miklb,

    Thx for responding.

    I first posted on Podz's test site and used a URI from a post on my blog. I wanted to see what the normal behavior of a successful trackback looked like. Immediately after publishing, I checked the trackback address field and it had cleared. I then checked my blog, and the trackback had logged correctly waiting for moderation.

    I reversed the process, sending the trackback from my blog to podz. After publishing, the URI never cleared from the field and it never showed on podz blog. I waited approx 1/2 hour. I don't remember checking what was in moderation (good catch). I also tested pingbacks with the same results. Podz to me (success), me to Podz (failed).

    Since I don't recall checking Podz 'waiting for moderation' trackbacks, I'm going to run a test right now.

    Stand by . . .

    Miklb,

    Sorry, some results. My trackbacks apparently never make to podz site. There is no indication of any communication and again, the URI never clears from the "Send Trackbacks To:" field on my site after I publish. It's as if during the publish routine, what ever procedure is suppose to handle the URI is failing. Alas, I wish I knew more PHP.

    More info -

    I found an event logged on my firewall (Smoothwall), which coincides with when I publish a post that contains a Trackback URI. Here it is:

    09:15:55 IN=eth2 OUT=eth2 SRC=192.168.xxx.xxx DST=192.168.xxx.xxx LEN=60 TOS=0x00 PREC=0x00 TTL=63 ID=59681 DF PROTO=TCP SPT=54928 DPT=80 WINDOW=5840 RES=0x00 SYN URGP=0

    My WordPress is running as a virtual server on my Apache. I'm wondering if this may be a host mis-configuration in my httpd.conf. I experience no other anomalies with my primary or my virtual hosts though.

    Just more pieces to the puzzle.

    If the updates are running via the async wp-cron thingy, I believe it tries to open a socket on the local machine to process a given event. If for some reason your firewall software is blocking that connection, that'd be an issue. That's the only thing I can think of.
