Subject Guacamole stream intercept - Need help
Date Thu, 05 Oct 2017 18:41:30 GMT

  Guacamole is a excellent library, we are using this for the remote
desktop operations i.e. execution of remote machine scripts by using the
client/server model.

   flow diagrams:

   Machine - 1 (guacamole server) ----> Machine 2 (remote system).

   Machine 1:
      Simple web application takes the script (can be anything) from the
user and using the guacamole stream intercepter we are sending the user
data to remote mahcine by opening stream by pipe instructions.

   Machine 2:
      Simple JNA jar listening on the static virtual channel for the
scripts input, once receive the script it will be executed and send back
the response i.e. write the response to static channel.

 Issues we are facing:
    1. How do we receive back the response in the machine1 by using the
guacamole library? we tried by intercepting the output stream by the index,
but output stream filter is always empty.
2. On java script level we are able to get the response data by onpipe()
listen method but requirement is to get the response on backend.
  Approaches we tried to get the response on the backend:

   1. Added our own socket class which implements guacamoleSocket interface
and trying to clone the stream.
   2. We are able to get the response data on the cloned stream but few
response data lose happened and procesing the streams performance got

Please suggest/guide as to what is going wrong and what needs to be
