==Fixing the Dashboard==  
==Getting Permalinks==
 
If your using a vhost, 'mod_rewrite' is not enabled by default. This means that Wordpress Permalink optinos do not work. You must [http://www.redbrick.dcu.ie/cgi-bin/writemail.pl?username=admin-request email the admins] and ask them to enable it for your domain.

==Getting it to work through the Redbrick/DCU Proxy==
 
Wordpress works fine without any of the following fixes. However you may find that a number of plugins or other features that attempt to access external sites and servers to Redbrick won't work. This is because there is no proper proxy support built in to Wordpress (or in php, depending on your point of view).
 
If your trying to get Wordpress to work on another site thats behind a proxy, just change "proxy.dcu.ie" to your proxy and "8080" (or is it "3128"?) to the correct port. These fixes do not, however, support authentication.
 
I did a quick "grep" and "find" of Wordpress and found 5 to 6 other calls to 'fsockopen' that do not support proxies. More than likely your Redbrick Wordpress blog will not send pings/trackbacks unless you do further modificatoins.
 
===Fixing the Dashboard===
      
      
But there is one final step. Once installed and working, you may notice that the "Dashboard", the page that welcomes you when you login, looks a bit ''blank''. With 2.0.3, Wordpress no longer crashes but it may not update very well. This is because Wordpress is attempting to download other websites relevant to Wordpress such as the Wordpress Dev Blog but can't because Redbrick is behing a proxy.

To fix this, open 'wp-include/class-snoopy.php' and search for 'var $proxy_host'. Set 'proxy_host' to "proxy.dcu.ie", 'proxy_port' to "8080".

===Akismet===
 
The Akismet anti-spam plugin won't work on Redbrick without modification. I'd recommend [http://unknowngenius.com/blog/wordpress/spam-karma/ Spam Karma 2] plugin for dealing with comment spam. However, if you want to use Akismet instead, you'll find that it seems to think that your Wordpress.com API key is invalid. This is because it doesn't handle sending post requests through the proxy.
 
You do not need to do this modification. Wordpress will work correctly without it.
 
Open 'wp-content/plugins/akismet.php'. Search for 'function ksd_http_post'. You'll need to modify this function like this:
 
<nowiki> // Returns array with headers in $response[0] and entity in $response[1]
function ksd_http_post($request, $host, $path, $port = 80) {
        global $ksd_user_agent;
        //$http_request  = "POST $path HTTP/1.0\r\n";
        //$http_request .= "Host: $host\r\n";
        $http_request  = "POST http://$host$path HTTP/1.0\r\n";
        $http_request .= "Host: http://$host\r\n";
        $http_request .= "Content-Type: application/x-www-form-urlencoded; charset=" . get_settings('blog_charset') . "\r\n";
        $http_request .= "Content-Length: " . strlen($request) . "\r\n";
        $http_request .= "User-Agent: $ksd_user_agent\r\n";
        $http_request .= "\r\n";
        $http_request .= $request;
        $response = '';
        //if( false !== ( $fs = @fsockopen($host, $port, $errno, $errstr, 10) ) ) {
        if( false !== ( $fs = @fsockopen('proxy.dcu.ie', 3128, $errno, $errstr, 10) ) ) {
                fwrite($fs, $http_request);
                while ( !feof($fs) )
                        $response .= fgets($fs, 1160); // One TCP-IP packet
                fclose($fs);
                $response = explode("\r\n\r\n", $response, 2);
        }
        return $response;
} </nowiki>
 
Now it should be able to verify your Wordpress.com API key and make requests to the Akismet server.

I identified another proxy problem with Wordpress. What exactly it effects I don't know but probaly trackback/pings to other sites because the xmlrpc uses 'class-IXR.php' which does not support proxies. I noticed the problem trying to get a plugin called [http://ebroder.net/livejournal-crossposter/ LiveJournal Crossposter] to work. See [http://thedeadone.net/news/livejournal-and-wordpress/ here] for details of what I tried originally.

I installed the latest version of [http://www.arnebrachhold.de/redir/sitemap-home/ Google Sitemaps], a plugin that generates a [https://www.google.com/webmasters/sitemaps/docs/en/about.html google sitemap] for your wordpress blog and tells Google about it. However when I activated the latest version and tried to generate a log I saw an error when it tried to ping Google. This is due to a similar problem as 'class-IXR.php' above.
