Hi,

Yes, the the DEMAND_ACTIVE_PDU gets twice sometimes.

I am trying to dump the data that the server sends when connected over
RFX [ when we get the black screen as no decoder is present yet.] after
the logon info PDU.

To analyse if the data after decrypt is RFX valid data?


I compiled the FreeRDP using the --with-debug option
and executed freerdp.
I also uncommented the HEXDUMP in surface.c file, surface_cmd() func.

I see a lot of the surface_cmd dump data.. after the connection
sequence.

I see the HEXDUMP with surface_cmd: cmdType 4 and 6. but the document
mentions CMDTYPE_SET_SURFACE_BITS which is 0x0001.
Am i reading wrong?

2: Why is the padding in the SHARE_CAPABILITIES missing?     


Please help me to understand as i have begun this project recently.


Regards
Vikas KM
