Question rfbdrake failed to extract public key from certificate


I'm running Mandriva's latest stable version and when trying to connect to a remote desktop using rfbdrake (from console, since if running it from the menu, it opens and as soos as I click on Connect, the window closes) I get the following message:

ERROR: Failed to extract public key from certificate
ERROR: send: Connection reset by peer
ERROR: Connection closed

Any clues?
I have already tried reinstalling it....

randon7533,

Have you found a solution to this problem??? I am having the same thing trying to RDP-connect from a 2X client. Intresting is that before activations License Server connection was OK, and right after I activated it and installed licenses - I am getting this message, and can not connect anymore.

Any clues would be highly appreciated.

RDPv5

I have been talking to my network admin and apparently this error has something to do with RDP version.
I used to connect to my company's servers using rfbdrake, but finally we realized I was getting this error whenever I tried to connect to a server running Windows Server 2008. I am no longer a Windows user so I don't know exactly but it seems Win Server 2008 is using RDPv5.2 and RDCv6.1 and rfbdrake is not yet compatible.
We also tried connecting to older Windows running servers and we didn't come across that error.
If I find out something else, I'll let you know.
Good luck!

+ info

According to wikipedia "Microsoft refers to the official RDP client software as either Remote Desktop Connection (RDC) or Terminal Services Client (TSC)." and also "128-bit encryption, using the RC4 encryption algorithm (this is the default security; older clients may use encryption of lesser strength). But because of the man-in-the-middle vulnerability in pre-version 6.0 implementations, in many circumstances the traffic can be decrypted along the way" and "Version 6.1 was released in February 2008 and is included with Windows Server 2008".
Finally, on rdesktop, as of May 2008, "rdesktop is commonly used on desktop Linux installations to connect to Microsoft Windows computers running Terminal Services, including Windows XP Professional, Windows 2000 Terminal Server, Windows Server 2003 and Windows Vista.".
As you can see Windows Server 2008 is not listed above....

I had the same problem except I'm using rdesktop on Debian. Installing the latest version of rdesktop (1.6.0) worked for me. Give that a shot.

I noticed that Microsoft runs version 4 of rdp however rdektop defaults to version 5

I used the following command and it worked fine

rdesktop -d yourdomain -g 100% 192.168.1.1 -4

Where -4 in the end runs the rdp client in version 4.

If you want to run this command in xterm then:

xterm -e "rdesktop -d yourdomain -g 100% 192.168.1.1 -4"


Hope this helps.
