Active session periodic screenshot

[dmantovani <dm...@salesianisesto.it>]

Hi to all,

First of all, thanks to all that have made Guacamole! It's fantastic!

I'm implementing it to my school to give the student an access to the lab
computer remotely, and it seam to work very well!

I've only a request that can help managing the students during the lesson:
there's any way an admin can see what's happening inside the connection? 
It would be awesome having a method to make a periodic screenshot of the
connections, that can be showed in the administration panel, or saved
somewhere that I can use later.

If there aren't any already prepared solution, anyone can point me out to
what do I need to make that myself? There's a simple way, using the api, to
reach the video stream? Any resource that explain to my how the video stream
work/is encapsulated?

Thanks to all
Cheers
Daniele

Thanks @ivanmarcus

Haven't noticed that possibility from the 'Active Session' page, and that's
interesting for the administrators (I've already started using it) :)
But I can't give all the teachers the administration permission (mainly for
security reason). 
I need something that do like a screenshot of the screen (eventually at low
resolution) and save it somewhere I can pick it up.

Meanwhile I'm starting inspecting the packets inside the websocket, looking
at the the possible type of data. I've noticed that it usually transfer only
the portion of screen that is changed with the coordinates.
I was thinking to, in some way, attach to the socket and give a command that
refresh all the screen and capture packet with the full update, but it
doesn't sound too clean to do to me...
There's a better way to interact with the tunnel or guacd process, giving it
the command to do a full snap for example in png, and getting it to save?
Are there any docs that talk about interacting with guacd or the tunnel? (if
is possible in some way)

Thanks again
Cheers

With Guacamole 1.1 an admin should be able to do this by default.

When logged in, if you list 'active sessions' then look at the 
connection name you should be able to click on that and view/interact 
with that connection.
