freerdp session unknown

Question

I'm trying to use xfreerdp to connect to our Windows 7 VM from a Debian 10 box and I keep getting the error session[UNKNOWN]. I've tried the xfreerdp 2.0 and 2.2 from backports and even the 3.0 nightly build as of 04/03/2021 and all have the same error.

Here is the command I'm using;

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

NOTE: It does work without the '/app:"cmd.exe"' connected but I want to just start the application and then close the connection after leaving that app.

Full error;

Answer 1

The same issue here. Update freerdp from buster-backports:

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

Besides, your windows VM should meet some requirements this:

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.
