What version of RDP is used in Windows 8?

I've tried to connect to Windows 8 Developer Preview via rdesktop 1.6 and freerdp 0.8.2 from linux and there was no success.

I've get:

ui_unimpl: NOT IMPLEMENTED: Unknown Capability Set 0x1E ui_unimpl: NOT IMPLEMENTED: Bpp 254

Although I could set a connection from Windows 7. What is the version of RDP on Windows 8? Is there any rdp client on linux that supports such version?

Maybe Remmina or Freerdp or Rdesktop connect to Windows Server 2012 but we have to be sure that is using the RDPv8 and it is not running on RDPv7 in a sort of compatibility mode.

Let me tell you, the performance gain of using RDPv8 is gigantic. See this video about remoting desktop is very interesting:

those guys in the video have done a excellent job evaluating Windows remote protocols.

For those stumbling onto this question:

Windows 8/Windows Server 2012 support RDPv8: (Wikipedia)

Remmina (remmina@sourceforge), implementing FreeRDP (FreeRDP), is able to connect to Windows 8/Windows Server 2012 -- I'm currently using Remmina to successfully connect to a WS2012 machine.

    size = width * height * (bpp + 7) / 8;

    if (bitmap->data == NULL)

FreeRdp is aiming to support win8

when I tried it logged it but fails to display properly

Bitmap Decompression Failed

Until release 1.0 gets out you can try it :

I am investigating

RDP underwent significant work in Windows 8 and likely does not yet have any support from non-Microsoft maintained clients. Remoting from Windows 7 should work properly. Some capabilities that were added in Windows 7 may now be taken advantage of which is why Windows 7 to Windows 8 may work while Linux to Windows 8 may not. That is to say, Windows 7's RDP client already supported the new capabilities.
