Summary: rdesktop and Vista build 5381

Initial Comment:
I used rdesktop to connect to the latest Windows Vista
(build 5381), and got the following error.

ERROR: modulus len 0x108
ERROR: send: Connection reset by peer
Broken pipe

I believe this is related to encryption.

Another person who had this problem.  I tested a snapshot on
2006-06-15 around 2:30PM EST or so and I can now connect to
vista but for some reason I can only use 24 bit color depth.
 Using -a 8 or -a 16 gives the error below.  Using the
official released version of the client I don't get that
error but I can't connect with it of course.

X Error of failed request:  BadValue (integer parameter out
of range for operation)
  Major opcode of failed request:  78 (X_CreateColormap)
  Value in failed request:  0x105
  Serial number of failed request:  8
  Current serial number in output stream:  9

Wow, it actually prints a useful error message, albeit
slightly cryptic to the layperson :)  Vista is sending a
2048-bit public key and rdesktop assumes 512 bits.

I've committed a couple of Vista fixes to CVS, including one
for this issue... rdesktop now works fine for me with Vista
Beta 2.

This seems to give a hint about the reason for this issue:

I really wonder why they didn't report it here, especially
that someone seems to have already analyzed the problem :/

It fails with that error even when that policy is not checked.

You have to clear the 'Allow connections only from computers
running Windows Vista' check box in the Remote Desktop
configuration of your Vista computer. Network Level
Authentication is not available in rdesktop (yet).
