I want to capture the traffic of my Client Server application but
When I tried WireShark I could not found any of my actual data
messages transferring over my application. The reason I found for
this is that my messages only reside in the modem memory or Sim card
and WireShark is unable to read the messages until and unless the
message come over to computer memory.
Given that Wireshark runs on that computer, it obviously cannot read
the messages until they're copied to the computer's memory.
However, your client/server application *also* can't read them until
they're copied to the computer's memory, if the application running on
that computer. If it's seeing the messages, then the reason is *NOT*
that the messages only reside in the modem memory (I don't think
they're stored in the SIM).
What OS are you running on the computer and, if it's Windows (as I
suspect it is), what version of WinPcap do you have installed?
