Hi Helmer, hi Stefan,

maybe i'm seeing it bad, but it seems that when
connected to a rdp server inside a x2gosession both the traffic when
watching a youtube video and transfering a 16MB file arrive at the same
port, in my case both connection when watched with iftop are receiving
all traffic at my port 33349 and being transmitted at :44126 server
port. Is this normal ?

That is something that Heinz, Alex and Mike will probably be able to answer better than me, but my gut feeling says that's expected behavior.

The SSH connecting process does this... (c) stands for client functionality, (s) stands for server functionality:

 o set up a master connection (normal ssh login, so to say), from X2Go client
   (c) to X2Go server (s).
 o over this master connection: set up one port forwarding tunnel for nxproxy
   (c) -> x2goagent (s) connection (graphics port)
 o over this master connection: set up one reverse port forwarding tunnel for
   audio stream. Applications in the X2Go session (c) can contact the
   client-side audio daemon (s).
 o over this master connection: set up one reverse port forwarding tunnel for
   SSHFS file/folder sharing. from within the X2Go session you can mount (c)
   client-side folder resources (s) via SSHFS

All the above named traffic can be listened to if you eavesdrop on the client/server port pair of the master SSH connection.

Hope that helps!

Greets,
Mike
