.</p>
<p>The output of the rdesktop command (on Linux) is:<br>
Failed to connect, CredSSP required by server.</p>
<p>On Internet, they suggest to untick the option "Allow
connections only from computers running Remote Desktop with Network
Level Authentification (recommended)".<br>

script:</p>
<pre>
<code>reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v UserAuthentication /t REG_DWORD /d 0 /f</code>

is never a solution and generally only a temporary
solution.<br>
Solution is to use package freerdp, for me worked like piece a
cake. @Debian Jessie</p></div>Denis Trofimovtag:help.appveyor.com,2012-11-13:Comment/382126292016-06-22T11:21:41Z2016-06-22T11:21:45Zrdesktop on Linux requires CredSSP<div><p>xfreerdp works like a charm.</p></div>Fábio Rizzitag:help.appveyor.com,2012-11-13:Comment/382126292016-07-28T00:09:14Z2016-07-28T00:09:14Zrdesktop on Linux requires CredSSP<div><p>xfreerdp is not working either . Going from Raspian on a Pi3 to
