Internet Usage Monitoring - conky style!

In Australia Internet users are limited to the amount they may download. Each Internet Service plan normally involves a speed and download limit. Failing to keep an eye on this and exceed your limit normally effects the user in question either by:

Paying exorbitant excess fees that can be as much as $150/GB!
Being 'throttled' by your ISP, in effect turning your lovely xDSL/Cable connection into something slower than dial-up.

As you can image, most people wish to avoid these. As a result ISPs provide a usage meter normally on their site, however you have to remember to view it, which unless you're diligent in doing so, you can still run over your quota.

Previously I've relied on the fabulous Firefox extension NetUsage, however this meant you had to have a browser open. This isn't always the case, and I found it frustrating to have to load a browser just to check my usage. (I could just login to the ISP's usage meter if I had a browser open).

I've seen others produce mrtg graphs and even Cacti graphs to display their usage; however they too also rely on having a browser open.

Ideally, I want to have my usage available, when I wanted, and without loading a browser.

I use conky on my desktop to display a range of information. It seemed a logical step would be to integrate a meter into my conky setup.

As you can see from the graph in the picture to the left, it displays a raw percentage of what has been used, as well as a visual bar graph. Below that is the raw data, showing exactly how much I've downloaded (~11.5GB), what my ISP believes my quota to be (55GB in this case), and when this billing period ends (the 13^th of every month).

I can now view my current Internet usage at a glance, without the need to load any additional program.

So how did I achieve it? Like many ISPs, my ISP provides an interface to the raw data. This is used by 3^rd party utilities like NetUsage and others to parse and generate the information. Internode (my ISP) has such an interface.

A quick and dirty script and I was able to spit out the graph in a format conky liked. Whilst this works directly with Internode, similiar ISPs have such interfaces and you will be able to hack the script to suit your own environment.

Below is the simple bash shell script used to generate the data:
#!/bin/bash # Get usage information from Internode's web page. # Setup to run once every half hour. # # Set the username and password Username=INTERNODE_USERNAME Password=INTERNODE_PASSWORD # Grab the details Temp=`wget -q -O - --post-data "username=${Username}&password=${Password}" --user-agent="Conky ISP Quota Grabber 0.1" https://customer-webtools-api.internode.on.net/cgi-bin/padsl-usage` # Generate the percent used. echo $Temp|gawk '{print $1/$2*100}'> /tmp/node-graph.txt Percent=`cat /tmp/node-graph.txt` echo $(printf %.0f $Percent) > /tmp/node-percent.txt # Break up the values into their respective parts Values=($Temp) echo "Used: $(printf %.0f ${Values[0]})MB Quota: ${Values[1]}MB Period Ends: ${Values[2]}" > /tmp/node-text.txt # Time to leave. exit

Sure it's not the most secure script (It stores your username/password in plain text). For me, the script sits on my desktop machine... and is protected by file permissions. The password I use for my ISP I also don't consider highly sensative. (It's important to note that most people throw around their password in clear-text across the Internet when picking up their mail with POP3! ). It does however do the job.

The above shell script I run every 30 minutes from cron.

It is then up to your ~/.conkyrc file to display the results. Here is the snippet of the appropriate code for the ~/.conkyrc file that will do that for you:

${color orange}INTERNET USAGE ${hr 2}$color ${execi 900 cat /tmp/node-percent.txt}% ${execibar 900 cat /tmp/node-graph.txt} ${execi 900 cat /tmp/node-text.txt}

There you have it, a simple ISP usage meter sitting right on your desktop.
It's not the most elegant or complicated program, however it serves it's purpose extremely well. YMMV.

Firefox 3 - What The?!

It seems various people are getting certificates for helping the Mozilla team set a new world record for the number of downloads in a day.

It's always interesting to see some of the organisations that made it possible!

Firefox 3 - Come break a world record!

At 3:00am AEST on Wednesday 18^th of June will herald the release of Firefox 3.

It's a big jump ahead from the heady days of Firefox 1 and Firefox 2 days. This version includes over 15,000 enhancements from the 2.x series. It's faster, funkier and doesn't eat anywhere near the memory Firefox 2 did!

The guys over at SpreadFirefox are attempting to set a world record, with the most downloads in a given 24 hour period. You too can be part of it!

I'm currently running one of the Release Candidates, and I've found it brilliant, all my favourite add-ons are now working flawlessly in it.

So help spread the world, Australia has around 30% of it's Internet users using Firefox these days. So people do understand and utilise the crazy fox based browser.

Moving more people off Internet Explorer will also ensure that Australian websites that wish to remain 'visible' will also start writing websites that are browser agnostic and follow the W3C standards (something IE only websites break heavily).

Microsoft claim that they are going to be moving fully to standards compliance with IE8, but don't hold your breath. We've been hearing that for years. As long as nasty ActiveX still hangs around like a bad fart in a crowded elevator it's not going to be compliant (or safe for that matter). And yes, IE8 will ship with ActiveX.

So hop to it! Pledge to download Firefox 3 on Wednesday, and become a World Record Holder!
