[Revathi Rangachari <masrrev@xxxxxxxxx>]

Hi

Please find attached the screen shot where I included the data that I
intent to capture.  This is Oracle 11i instance application running on
an IP and port no.8045.

The wire shark displays data when the application is running and
retrieves data.  But when I enter data in a Form and say Submit
Wireshark does not display anything on  the screen but the Status Bar
displays the number of Packets captured and the number keeps
incrementing.

When I save this, I do see the contents of the data captured.  But
they are in bytes or hex format ( the format) of which I am not very
sure.  The trace starts at Ethernet layer.

My question is how to get this data to a readable format?

Thanks in advance
Revathi
