Flick




Asher Glick           Tor E Hagemann
What we have done

Designed and implemented an elaborate client/server
connection structure
 
Learned how (not) to use Git
 
Researched how X works, extensively
 
Failed multiple times trying to find shortcuts inside X to make
our lives easier
 
Further developed how Flick will work conceptually
Networking Layout

Three Networking Modes
 
Networking Layout

 
 
Networking Layout

        LAN-Based Network Configuration
 
How X Works                   (in a nutshell)

Program uses X libraries for user interface

X takes the output from the program
 
X puts the input out onto the screen

User's input is recorded by the X and analyzed by the program
How Networked X Works (in a nutshell)

Program uses X libraries for user interface
 
X client takes the output from the program
 
X client sends info to the X server on the remote computer
 
X server put the input out onto the screen
User's Mouse and Keyboard are sent via the X server
 
Program never knows that it is not running on the host
computer
Difficulties and Discoveries

Transferring information from X clients is a difficult problem
 
Programmatic creation and manipulation of X clients (and how
some projects have tried, or failed, doing this)
 
Switching display environment mid-program using the xhost
program for remote connection authorization

Authentication methodology (a.k.a. why not SSH?)

How will we make all this work in Windows again?
Avoiding Convalescence

    Reliance on X11
 
    What about Wayland?
      The Problem(s) with X
      How Wayland solves them (without breaking
      everything)
 
    Cross-Platform Compatibility
       Xming, pthread, Winsock, (oh my...)
Future Plans (short term)

Simulate an SSH-like tunnel that will initiate an X program's
start up
 
Encrypt the simulated tunnel to protect the users
 
Pipe the socket to which ever computer the user wants to
send it to and have the remote X server accept it
Simulation
Thank Yous

   Sean O'Sullivan

Why hello there, i am glad that
               yo found me, it is hard to do!
