FreeRDP

FreeRDP is a free remote desktop protocol library and clients

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Enjoy the freedom of using your software wherever you want, the way you want it, in a world where interoperability can finally liberate your computing experience. The nightly builds are installed into /opt/freerdp-nightly and can be installed in parallel with the distributions regular freerdp package. Network tracing of RDP can be quite a challenge due to a number of factors such as encryption, compression, and the fact that these protocol features cannot always be disabled or worked around. One of the easiest way of decrypting RDP traffic is to configure the server with a self-signed certificate for which the private key is known, and then use this certificate with a network tracing tool to automatically decrypt the packets.
