Xvfb-run as a subprocess in Django running xfreerdp fails

Question

I have a ThreadPoolExecutor object( rdp_connector_global ) in a Dockerized Django application's view method calling the below method( _rdp_connect ) via submit as follows:

rdp_connector_global.submit(_rdp_connect, login.ip_address, login.remote_port, login.username, login.password, login.rdp_width_pixels, login.rdp_height_pixels)

def _rdp_connect(hostname_or_ip, port, username, password, rdp_width_pixels=1920, rdp_height_pixels=1080):
    domain = None
    username_simple = username
    if "\\" in username:
        split = username.split["\\"]
        domain = split[0]
        username_simple = split[1]
    elif "@" in username:
        split = username.split["@"]
        username_simple = split[0]
        domain = split[1]
    connection = None
    if domain is None:
        xvfb_args_str = "/usr/bin/xvfb-run /usr/bin/xfreerdp /sec:tls /u:{0} /p:{1} /w:{2} /h:{3} /v:{4}:{5} /cert-ignore".format(username_simple, password, rdp_width_pixels, rdp_height_pixels, hostname_or_ip, port)
        connection = subprocess.Popen(xvfb_args_str, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
    else:
        xvfb_args_str = "/usr/bin/xvfb-run /usr/bin/xfreerdp /sec:tls /d:{0} /u:{1} /p:{2} /w:{3} /h:{4} /v:{5}:{6} /cert-ignore".format(domain, username_simple, password, rdp_width_pixels, rdp_height_pixels, hostname_or_ip, port)
        connection = subprocess.Popen(xvfb_args_str, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
    logging.info(connection.communicate())
    connection.wait()
    logging.info(connection.communicate())

Xvfb and freerdp are installed in the Docker container correctly. The login command succeeds when I run it from Django shell or the shell inside the Docker.But the same command fails to login to the remote Windows machine when running via code. When running via Django I get a ERRINFO_LOGOFF_BY_USER after 30 seconds of unsuccessful wait to connect to Windows machine.

Answer 1

I finally solved the problem. It was nothing to do with freerdp or Docker or Xvfb. The login,password was not decrypted before use. hence the login failure.
