freerdp 會話未知

我正在嘗試使用 xfreerdp 從 Debian 10 機器連接到我們的 Windows 7 VM，但我不斷收到錯誤會話

$$ UNKNOWN $$. 我已經嘗試了來自 backports 的 xfreerdp 2.0 和 2.2，甚至是 2021 年 4 月 3 日的 3.0 nightly build，並且都有相同的錯誤。 這是我正在使用的命令；

/opt/freerdp-nightly/bin/xfreerdp /u:<admin user> /p:<pass> /v:192.168.200.189 /app:"cmd.exe"

注意：它在沒有連接’/app:“cmd.exe”’ 的情況下工作，但我只想啟動應用程序，然後在離開該應用程序後關閉連接。

完全錯誤；

這裡同樣的問題。從 buster-backports 更新 freerdp：

sudo apt install -t buster-backports libfreerdp-client2-2 freerdp2-x11

此外，您的 windows VM 應該滿足一些要求：

RemoteApp Tool requires:

   Microsoft .Net Framework 4
   Windows 7 Enterprise or Ultimate -or-
   Windows 8 Enterprise -or-
   Windows 10 Enterprise or Education -or-
   Windows XP SP3
   It also works with Windows Server 2008 and newer.

Note: If you try to host RemoteApps on any other edition of Windows (eg Win 7/8/10 Professional), the tool will run but RemoteApps will not work. The RDP client will appear to be connecting, then just disappear.
