I can connect from the XP virtual machine (with MSTSC updated to version 6) or with a W7 virtual machine, both running under a VirtualBox in Linux host.

But I with to connect from Linux. I downloaded FreeRDP-x11 and Remmina, but nothing good happens.

Do I have to compile something, or what else do I have to do? I guess this issue has to do with the RDP 6 protocol, Linux clients are compatible with RDP5, is that the problem?
