To enhance security, I changed my system umask in /etc/profile to 007. After this, creating new websites would no produce websites that could use PHP. I got errors such as: Code: [Sun Dec 30 09:13:25 2012] [warn] [client 184.108.40.206] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server [Sun Dec 30 09:13:25 2012] [error] [client 220.127.116.11] Premature end of script headers: index.php I tracked the problem down to the entries in the /var/www/php-fcgi-scripts directory that were now created with 750 instead of 755 mode. Once I manually changed the entries back to 755, everything worked again. In looking at the code, I see in: /usr/local/ispconfig/server/plugins-enabled/apache2_plugin.inc.php on line 958: exec('chmod 755 '.$fcgi_starter_script); That is fine for modifying the mode of the .php-fcgi-starter file, but the directory is created on line 925 and is created with the default umask. That's the problem. So, before this line, I inserted: umask(022); and all worked again. Perhaps this umask should be in a more global or earlier location. Can any of the devs suggest a more permanent fix?
