# Bad trackback link. mod_rewrite problem ?

 * Hello,
    I am getting bad trackback URL information in my posts . For example,
   when my post is at:
 * > [http://www.fabianrodriguez.com/wp/archives/2004/02/24/pmachine-20-import-to-wordpress](http://www.fabianrodriguez.com/wp/archives/2004/02/24/pmachine-20-import-to-wordpress)
 * … the trackback info says:
 * > The URI to TrackBack this entry is: [http://www.fabianrodriguez.com/wp/wp-trackback.php/159](http://www.fabianrodriguez.com/wp/wp-trackback.php/159)
 * If I try going to that link I get the following error:
 * > **No input file specified.**
 * I am using the following permalink structure:
 * > /archives/%year%/%monthnum%/%day%/%postname%/
 * and mod_rewrite rules (as generated by WP):
 * > RewriteEngine On
   >  RewriteBase /wp/ RewriteRule ^archives/([0-9]{4})?/?([0-9]{
   > 1,2})?/?([0-9]{1,2})?/?([0-9a-z-]+)?/?([0-9]+)?/?$ /wp/index.php?year=$1&monthnum
   > =$2&day=$3&name=$4&page=$5 [QSA] RewriteRule ^archives/category/?(.*) /wp/index.
   > php?category_name=$1 [QSA]
 * I’ve noticed other sites using the exact same (default) rules without problem,
   like [Alex King’s](http://www.alexking.org/).
    Thanks for any hints on this.

 * TrackBack links are not meant to be viewed in the browser. They are only used
   for blog-to-blog linking. Matt has [some notes about this](http://photomatt.net/archives/2004/01/06/problem-with-trackback/),
   which could arguably be called a flaw in the design of TrackBack. PingBack is
   more intuitive, since it doesn’t require any special setup or interaction, but
   doesn’t have the capability to carry excerpt information, by default. It would
   be nice if there was an easily implemented protocol that could combine the best
   features of both systems.

 * Are you sure you got all the mod_rewrite stuff copied out? That error sounds 
   rather like one I got once by thinking that the few visible lines were all there
   was. Maybe it’s a version-difference, but looking at some-random-nightly, I’ve
   got nine rewrite rules, including one for wp-trackback.php.

 * Not sure it is the same problem. The other poster doesn’t have mod_rewrite. What
   you are looking for is autodiscovery to redirect to the right post. Having never
   clicked on a trackedback link, I never noticed that it was “broken”.
