Not long before XNet announced their new plans I wrote a usage meter in php.
The probably more unusal part of it is that I tried to make it look as best I could on my Nokia 6165i.
After XNet added the torrent plan and added the details showing off peak and peak traffic I added that in as well.
I have tested it on my laptop with XAMPP 1.6.3a running on winxp pro and on Free BSD 6.2 running apache 2.0 and php 5.2.3
To setup download the files place in a web server with write permissions on the folder.
Point your web browser to the folder and enter your details.
You may be asked for a username and password, the default should be admin admin.
If your interested in trying it, it can be downloaded from here http://homepages.xnet.co.nz/~bjgreer/meter.html
Any comments or suggestions or comments are welcome.
