I have been finding it difficult to exactly find the usage details of my dataone connection for quite some time.After a bit of search over the internet i found some interesting tools which i would like to share with you.
1. Shaplus DataOne Usage tool (It is not open source)
This one was one of the first tool which worked but as said before its not a open source, so cant guarantee the security of your username and password. No open complaints have been recieved till date.
2. DUF( DataOne Usage Finder)
This one claims to be a open data source code but the reality is that it is hosted on sourceforge.net which hosts open source software, but you cant find the source of this software. I personally use this one as this one has a good graphicaly presentation of data with graphs, daily usages, cached pages etc..
3. Datafox
This one is a firefox [ https://addons.mozilla.org/en-US/firefox/addon/5471 ] extension and would only work with firefox. Its pretty lite compared to the other two but works pretty much same compared to other data usage finders. For Firefox users this one is a boom.
Atlast its you decession which one to use or stick to the traditional BSNL site if you dont have complete faith on any of these softwares.
Share your views and experiences about BSNL, its usage, difficulties etc….
Would be happy to help you with your problems..
