Does an RDP client library under Linux exist?

Question

Are there any libraries for connecting as a client via Remote Desktop Protocol (RDP) in Linux? The language used is secondary to the issue of existence. Any mainstream language would do (e.g. C++, Perl, Java, Ruby, PHP, Python), and even less popular ones like OCaml or Scheme.

Is there any option available other than taking the rdesktop source and hacking a library out of that?

Answer 1

You can look at these implementations:

• FreeRDP (Apache License) - mostly C.
• FreeRDP C# bindings
• FreeRDP-WebConnect for HTML5 stuff
• rdesktop (GPLv2) - mostly C.
• rdpy (GPLv3) - python but bitmap stuff is written in C (borrowing code from rdesktop)
• properJavaRDP (GPL) - java

Non portable implementations:

• Terminals (MS-CL) - visual studio project.

Answer 2

There is a set of cross-platform open source RDP libraries available in FreeRDP project. They are written in C and under Apache Licence 2.0. See http://www.freerdp.com
