Yes, my aim was to spin up EC2 instances only when someone 'selects' the
connection for them. As users will have multiple options, I don't want all
instances to be started when a user logs in. And then closed on exit (if no one
else is using that instance)
I've only been playing with the simple code given in the doc's for handling a
tunnel connection event. So what I did was the below. But the 'Active
connections' array is empty and 'Connections Directory' contains the list of
all connections that user has access to. But I can find no other way to find
information on the currently selected connection. I took a closer look at where
the tunnelconnectionevent is called and I see the currently selected connection
is not passed to the listener (is that right?). If that’s the case , that I
can't do what I was hoping to do. (I hope I'm missing something?)
else if (event instanceof TunnelConnectEvent) {
logger.info("received Guacamole tunnel connect event notification");
AuthenticationProvider AuthProv = ((TunnelConnectEvent)
event).getAuthenticatedUser().getAuthenticationProvider();
UserContext UserCont = AuthProv.getUserContext(
AuthProv.authenticateUser( ((TunnelConnectEvent) event).getCredentials() ) );
Directory<Connection> Conn = UserCont.getConnectionDirectory();
Directory<ActiveConnection> Active =
UserCont.getActiveConnectionDirectory();
logger.info("Connection Directory = ",
Arrays.toString(Conn.getIdentifiers().toArray()) );
logger.info("Active Connections = ",
Arrays.toString(Active.getIdentifiers().toArray()) );
thanks

Can you explain at a little bit higher level what you're trying to accomplish?
Spin up a cloud resource (e.g. EC2 instance) when someone logs in, and spin it
down when they log out? Or something else? Can you share the code you've
written so far - is it on GitHub somewhere?
