Prevent VNC display from stretching?

[amlamarra]

Is there a way to get VNC connections from stretching (or shrinking) the
display by default? I'd like to keep it at 100%.

I've now reopened GUACAMOLE-296 and quoted the information above.

I have found the source of the issue, but still not full solution. It looks
like the problem is in Chrome, the Firefox is working normally. When remote
app tries to access microphone, FF pops dialog and asks for permission to
use the mic.

In the Chrome, the dialog for allowing mic access does not show and
microphone is always blocked. It is even not possible to manually allow use
of the mic - clicking on the site setting shows microphone as blocked and
combo is disabled.  In the global options, mic is set to "Always ask", no
exceptions for my site. I am using Chrome 64.0.3282.167 on Linux Mint 18.3.

The other issue is that I still need to patch Guacamole server build with
workaround from Guacamole-296 issue (
https://issues.apache.org/jira/browse/GUACAMOLE-296?focusedCommentId=16054277=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16054277).
This issue is resolved as "Cannot reproduce", but I can reproduce it always
on my server installation (Ubuntu 16.04.03 LTS, libfreerdp 1.1 from repo,
Guacamole server 0.9.13 manually built).

Hello,


I am trying to enable audio input in the Guacamole 0.9.13, libfreerdp-1.1
(default from Ubuntu repo)  and Windows Server 2012R2. The audio playback
and recording is tested with Skype and working when used directly with
xfreerdp.

With guacamole it is possible to make connection, but audio recording is
not working. I have experienced issues with disconnets on recording
(Guacamole-296, https://issues.apache.org/jira/browse/GUACAMOLE-296), the
proposed fix was applied and there are no disconnects. However, the
recording still does not work -  Skype reports problems with remote
microphone.

Re: Disable Websocket

[yozh]

Thank you for the reply. They are also doing HTTPS inspection so it does not
help... I was able to get ws to fail and it does fall back to the HTTP
tunnel, but seems only connects half the time and when it does it fails in
about 20 seconds... Thank you for the help, I guess I am out of luck.

I would recommend instead setting up encryption through enabling SSL on
your Nginx server, as that would likely both work around the problems with
the interfering proxy while also providing necessary security. It's
generally not recommendable to access remote desktop services without any
encryption.

You can effectively disable WebSocket by configuring your Nginx reverse
proxy to return a 404 for /guacamole/websocket-tunnel (assuming you are
serving Guacamole from /guacamole - adjust this accordingly if you are
using a different path). It is likely that the interfering proxy is
allowing WebSocket to partially succeed, hence the lack of proper fallback,
but the hard 404 error will force Guacamole to fallback to HTTP. Beware
that:

* The HTTP tunnel has reasonable performance but will not be as nice as
WebSocket.
* If your proxy interferes with WebSocket, there's a good chance it will
interfere with HTTP as well. If you cannot use encryption, and the proxy
prevents any form of streaming from working properly, you may be out of
luck.

Re: Disable Websocket

[yozh]

Hello,

I brought this up before, but never got an answer. How do I disable
websockets and use HTTP tunnel ? I`m using nginx as a proxy for port 80, and
it doesnt seem to fall back to HTTP, just times out since websense is
blocking websockets. How to I force to use HTTP ?
