GNOME Bugzilla – Bug 740663
Remote desktop to Windows 7, 2k8, and s12 no longer working
Last modified: 2014-11-26 08:37:01 UTC
I used to connect using RDP over a VPN connection to work, after upgrading to Ubuntu 14.04 LTS this is no longer working. Mind you I have tried the simple changed to dconf, using dconf-editor, to disable "require-encryption" for remote access, but I am almost positive this is for people connecting remotely TO their Ubuntu box. Also lots of sloppy nomenclature with people referring to VNC as "remote desktop". This is about RDP protocol from an Ubuntu box to various windows boxes. My Remmina client still connects to the older Windows 2003 Server as it always did. Point me to the logging locations, could not find anything obviously related to any of this in /var/log. Linux is completely baffling to me now - the old ease of the OS files layout, like UNIX, is gone, but the GUI is incredibly under-powered to actually manage the machine.

I launch Remote Desktop Viewer using the GUI, so the command line spec to launch vinagre is kind of an adventure for me. If that command *launches the GUI app* I am glad to scrape what is in the command window, but if it launches some interactive command line session that won't mirror my user experience. I will try to grab some logs tomorrow. The version of vinagre is unknown to me, but it was whatever was in the Ubuntu 12.04 LTS release.
> If that command *launches the GUI app* Yes it does.
I tried it as you suggested. The operation was different- while it launched the GUI, it requested the password on the command line. I entered the windows PW to my workstation, here is what it printed out: stuart@wildebeest:~$ vinagre --gtk-vnc-debug connected to ws-sholme:3389 Password: The host key for ws-sholme has changed @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the host key sent by the remote host is 95:ef:e0:a2:63:ed:b7:90:0b:58:3d:bc:16:26:9c:99:85:1f:04 Please contact your system administrator. Add correct host key in ~/.freerdp/known_hosts to get rid of this message. Host key for ws-sholme has changed and you have requested strict checking. Host key verification failed. SSL_write: Failure in SSL library (protocol error?) Authentication failure, check credentials. If credentials are valid, the NTLMSSP implementation may be to blame. Note that I don't think the remote host credentials have changed, but I can check with my SysAdmin. The real problem here is I am going into surgery tomorrow, and won't be able to go to work for 6 - 8 weeks. Thus I was kind of hoping to be able to remote login... but that looks like it's not in the works. I will email my sysadmin at work and ask if he changed the NTLMSSP.
Certificate and password handling with RDP is fixed in Vinagre 3.14, but the workaround is to use xfreerdp (the command-line RDP client provided by FreeFDP) directly. *** This bug has been marked as a duplicate of bug 724133 ***
