Try setting "security=tls" or "security=any" and "ignore-cert=true".

In addition to TLS, as Christian suggests, you may also need to configure the connection to ignore the certificate, as the certificate of your RDP server is likely self-signed. > My host is Win8.1 Pro.

Unfortunately, while this sort of thing is possible with the libraries we use for VNC (libvncclient), SSH (libssh2), and telnet (libtelnet), the FreeRDP API simply doesn't provide hooks for that sort of information. Applications which consume the FreeRDP library (like Guacamole) can obtain the disconnect reason sent from the RDP server in the form of an error code, and there's been recent work to expose that information, but that wouldn't help you here. The true details surrounding why a connection has failed are only logged internally by FreeRDP. For sake of debugging, it can be helpful to try running guacd in the foreground using the "-f" option (you'll need to kill any existing guacd processes first). That will allow you to see FreeRDP's internal log messages, which it sends to STDOUT / STDERR. > Only such clutter as "Connection ID is "$42bb300e-fac7-4d"? My logging level > in logback.xml is set to *warn*. The "logback.xml" file only controls the logging of the web application. The message above is actually logged by guacd. It's not clutter, but if you don't want those kinds of messages to be logged, you'll need to configure guacd's log level, as well, which defaults to "info": http://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#guacd.conf [4] That said, since you're currently debugging the behavior of a connection, I don't recommend reducing the verbosity of your logs at this time. - Mike --- DTIC - Departamento de Tecnologias de Informação e Comunicação INSTITUTO POLITÉCNICO DE COIMBRA | Serviços da Presidência VOIP: 301103 Em 2017-07-03 09:54, [email protected] escreveu: > The guacamole machine is Linux Ubuntu 16.4 and the remote machine I want to > connect to is a Windows 10.
