I think Growl is a pretty awesome little notification app, I use it for absolutely everything and thought I would cook up a simple way for anyone to relay growl messages to their nodes – even from remote events.

What you need :

• A Local web server (with PHP of course)
• Remote machine must have curl (unless you are good with javascript)

Download the class.growl.php from google code and toss it in your web root.  Create a new file called growler.php or growlnotify.php.  Within it you can paste the following :

Set your webserver to listen on some obscure port and forward it through your router.  You can now use curl to post messages from a remote location to all of the nodes you specified in the associative array above  as such :

curl -d “message=some message `date`” http://your-web-server-ip:port/filename.php

This is a simplified explanation how I wrote Growl notifications for Asteristickies.

Have fun.
