httpd.conf
Adding the following lines to the Apache 2.x configuration file will associate .php files with PHP, given the PHP 5 module (DLL file) is also loaded through the configuration: <FilesMatch \.php$> SetHandler application/x-httpd-php </FilesMatch>
/etc/named.conf
If you're using Apache, it may be as simple as turning ServerSignature Off in your Apache configuration file.
The 'current directory' is where you are in this moment, the 'standard directory' is where something usually is (quite vague definition, isn't it?)... for example, the standard directory for the apache configuration file is /etc/apache, for temporary files it is /tmp
/etc/smb/smb.conf or /etc/samba/smb.conf.
Configuration settings file can be viewed either in notepad or browser depending on the type of configuration file. If the configuration file has extension - "INI", then it can be viewed in notepad or textpad. If the configuration file has extension - "XML", then it can be viewed both in Notepad and Browser.
httpd.conf is probably the most important. It holds every setting of the Apache Server. One typo in this file can send your server into a self-destructive spiral of doom. I'm not sure about the others, hope this helped. Fireblazer
