Hi Sudhakar,

Thank you very much for your support. Suresh gave us a machine( in IU to deploy the server. But unfortunately we are
having some ssh issues when logging to that server . I will contact Suresh
and get the issue fixed and deploy  an instance of the server there so that
you can configure and test the parsers by your self.
