wayne street	Monday 19 February 2007 10:09:50 am I am installing on a sub-domain... I uploaded all files to my host. I then run the install wizard. It came back with directories that I needed to chmod, so I did that. It then progressed to outgoing email setup. I choose 'Sendmail/MTA' and hit next. I then get: 406 not acceptable An appropriate representation of the requested resource /index.php could not be found on this server. I check and thee ez publish index.php file is in the subdomain root directory. Any suggestions.
Claudia Kosny	Monday 19 February 2007 11:47:21 am Hi Wayne If you google around a bit you can find quite a few pages stating mod_security as the reason for this problem. The recommended solution is to add the following to your .htaccess: <IfModule mod_security.c> SecFilterEngine Off SecFilterScanPOST Off </IfModule> Please note that I don't know whether doing this is a good idea as I don't have the slightest clue what mod_security is actually doing. On the other hand this htaccess addition was recommended for drupal, joomla, wordpress ... so if you want to use a cms it seems that you have to live with it. Claudia

Three Quarks	Wednesday 09 May 2007 1:45:15 am check your error log for apache mine was error_log you should see a mod_security error message mine was [Wed May 09 02:30:33 2007] [error] [client 210.209.74.203] mod_security: Access denied with code 406. Pattern match "!(/imp/login\\\\.php)" at HEADER("Referer") [id "300018"] [rev "3"] [msg "Generic PHP code injection protection via ARGS"] [severity "CRITICAL"] [hostname "www.somedomain.com"] [uri "/index.php?option=login"] [unique_id "gnZhgH8AAAEAAEa8QMAAAAAA"] grepped 300018 in /etc/httpd/conf.d/ the id for the error message found mod_sec-rules.conf had a matching rule the rule was "really broad furl_fopen attack sig" There are two version of this same rule. Commented out the 1st version. restarted httpd / apache. error message no longer appeared.
Three Quarks	Wednesday 09 May 2007 2:52:45 am quick update. i rewrote the rule as follows:- SecFilterSelective REQUEST_URI "!(/tiki-objectpermissions\|aardvarkts/install/index\|/do_command\|banner_click\|wp-login\|tiki-view_cache\|/horde/index\|/horde/services/go\|/goto\|gallery2?/main\|ad-?server/adjs)" "chain,id:300018,rev:3,severity:2,msg:'Generic PHP code injection protection via ARGS'" SecFilterSelective REQUEST_URI "\.php(3\|4\|5)?(\?http\|&http\|\?ftp\|&ftp)" chain SecFilterSelective HTTP_Referer "!(/imp/login\.php)" the original ARGS option was being ignored!
