nothing really happens. Only on port 7676 there is something. It connects, I can type, but do not answer. Do you have an idea what is 7676?

you can send upnp controll messages to this port like get channel list and start dualview if the device supports it.

for the "service assistance" 4443 port looks like the client needs to present ssl certificate...
(/mtd_exe/WebServerApp/webserver is the directory for the webserver on e-series tv's, think it's no big different to bd-player)

Code: Select all

How can I do this? Is there a windows program to do that?

Port 6000 is used for X11 server; That would ne nice to run xterm (or something else) on a computer with display on TV ;)

The server is using MIT-MAGIC-COOKIE-1 to allow connection... but I can't find it
If we had an app that uses this server, it would be easy to steal the cookie with tcpdump.
Any idea to find this cookie ?

Code: Select all

>export DISPLAY=192.168.1.107:0.0
>xauth add 192.168.1.107:0.0  MIT-MAGIC-COOKIE-1 00000000000000000000000000000000
>xterm
Invalid MIT-MAGIC-COOKIE-1 key

xauth list (on device) or .Xauthority file (somewhere on device), but 99% sure that X just listen on tcp but won't/can't accept connections

I already checked for xauth on device

This is not a standard X11 server : no X daemon; instead, exeDSP is using libXserver.so::InitXServer() to start a thread for this.
In turn, libXserver.so uses libos.so to check the cookie (MitCheckCookie()). However, the function that creates the cookie (MitAddCookie()) is never called, from any lib...

So, you're maybe right : X11 is probably used only in smarthub, locally, and they forgot to disable port 6000... but it's worth trying !
