all,
just to inform you that since a month there is a new version of rdesktop, 1.6.0.
This is essential as the latest rdesktop package in the official feeds is 1.5.0.
With 1.5.0, rdesktop always fails after a few seconds or minutes.
You can easily modify the existing .bb file to build it. For "simple" users, I attached the ipk.
