Dynamic Session Creation
Hi all, I'm currently trying to figure out if and how a dynamic session creation mechanism can be implemented in a Guacamole extension. Let's say I have a bunch of machines which can host graphical desktop sessions and I have a script based mechanism to initiate the request to create such a graphical session on one of the machines and add the information about the session into the guacamole_db (SQL). If a user, who doesn't own a graphical session yet, logs in to Guacamole, I'd like to trigger/call the script in the backend which creates the session and adds the information to the guacamole_db. I've looked through the extension mechanisms in Guacamole and it seems that event listeners could be used to trigger the mechanism in the backend on user login. Has someone knowing the architecture of Guacamole an idea whether - the user will be connected to the just created session, if the session creation is done in a listener on an "AuthenticationSuccessEvent" happens, - there's any way of informing the user about what's going on in the backend from within such a listener function (e.g., display a banner "Session creation pending. Please be patient." or something similar, until the session is ready for connection). Thanks for any answer or tip.

I'm presuming you're talking some sort of VNC session, since RDP doesn't usually require any setup, but maybe you can clarify this a bit? Even for VNC you can set it up with xinetd such that sessions get created when users connect, so some additional information here on what exactly you're trying to do would be helpful. > > I've looked through the extension mechanisms in Guacamole and it seems > that event listeners could be used to trigger the mechanism in the backend > on user login.

Your extension should also be able to make the connection happen automatically - in addition to writing the event listener implementation, you'll likely need to write some AngularJS code and perhaps even a REST endpoint in order to pass information about the newly-created session between the Java back-end and the web browser front-end and make the connection happen, but this should be doable. It's definitely a little bit involved, but it all sounds doable. Sounds like you're already reading the manual, which should be a good place to find that information, so I'd just continue to look through that and the existing code to figure out how to do what you're trying to do. You can also e-mail back here with any specific questions you might have and the community will jump in and help as we can :-). -Nick
Re: Copy paste clipboard only
i think that Guacamole isn’t right way to accomplish your use case, you should use something that aims to share clipboard, for example https://www.havefun.cz/projects/haveclip/ -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
Guac on Chromebook - No sound
Hi Everyone: Getting ready for an important customer demo - need help. Setup guac 0.9.13 WIndows 2016. When we connect using a WIndows PC, or Mac OSX sound input and output work fine. When we use the same connection from a Chromebook or an iPad, no sound input or output. Questions: - Has anyone been able to get sound to work on Chromebook/iPad? - Any insights/pointers? Thanks! -- Antony Awaida www.apporto.com

My daily machine has been a Chromebook / Chromebox for several years now, as I do all my work over guac. I can't speak to whether recent versions of iOS support audio (my test iPad is ancient), but caniuse shows that it should: https://caniuse.com/#feat=audio-api All Guacamole needs for audio support is the Web Audio API. - Mike
