UPDATE: There's a new version of the script out with more options and better configurability. Check it out

Anybody who even occasionally stumbles on my blog should know full well by now that I have some personal beef with Dhiraagu. It's not that they suck..per se. It's just that I feel that they could, as a company, do much better.
Having said that, not having plain-text data available on the ADSL usage page (which incidentally has been trapped in a time-freeze-bubble since the 1960's) is just plain stupid on the part of whoever designed it. No matter though, where there is a will, there will be a way.
Previously I used to do it like this; Simply grabbing the graph image from the concerned page and popping it into eog so I can have a look.
wget --post-data "web_user=${username}&web_pass=${password}" -p http://dsl.dhivehinet.net.mv/login.php;eog ./dsl.dhivehinet.net.mv/comparision_graph.php;rm -r ./dsl.dhivehinet.net.mv
substitute ${username},${password} and eog as necessary.
But that wasn't enough..what If I wanted something in Conky or something to that effect? That would be a lot more convenient than having to look at that fart of a graph they have up there. So I came up with this simple solution.
SIMPLE but NOT ELEGANT... this is ugly, but it gets the job done.
