Web UI Installation

  1. Extract tarball contents to somewhere under your web root
  2. Rename sample.config.inc.php to config.inc.php, after optionally changing values in it
  3. Visit page in web browser
  4. Pass URL to your friends to show off

URL arguments

  • ?out=xml - XML output (requires SimpleXML extension)
  • ?out=json - JSON output
  • ?out=jsonp&callback=functionName - JSON output with a function callback. (Look here: http://www.json-p.org/ )
  • ?out=php_array - PHP serialized associative array
  • ?out=html - Usual lightweight HTML (default)

Extensions

  • See a list of php files in src/Linfo/Extensions/
  • Open them and look at the comment at the top of the file for usage

Troubleshooting:

Set $settings['show_errors'] = true; in config.inc.php to yield useful error messages.

TODO:

  • Support for other Unix operating systems (Hurd, IRIX, AIX, HP UX, etc)
  • Support for strange operating systems: Haiku/BeOS
  • More superfluous features/extensions
  • Make ncurses mode rival htop (half kidding)
