I need enable TCP connections to my system, for use graphical applications in marionnet, network simulation system, in debian squeeze.

In older versions of debian it is achieved with System|Administration|Login Window -> uncheck “Deny TCP connections to the Xserver”. but in squeeze I have no idea.


EDIT: I have the answer: take a look here


The recommended way to execute GUI applications is over an SSH connection. Install an ssh server (openssh-server package) on your system. Run ssh -X or put ForwardX11 yes in ~/.ssh/config on the client side.

  • And do you think that works for my specific case(marionnet)? – rendon Nov 3 '11 at 0:21
  • @D.D.C I'd never heard of marionnet until now, but I don't see why not. If you have trouble with it, feel free to ask questions here (but I recommend giving more information, since it's not a very common program). – Gilles 'SO- stop being evil' Nov 3 '11 at 0:29
  • Marionnet(marionnet.org) is a network simulation system, by each pc it runs a virtual machine(gnu/linux OS), then a command line prompt is shown exactly like a normal pc running gnu/linux, all command line programs works fine but if I wanna run a graphical app it fails with a message like this: Gtk-WARNING **: cannot open display:'. – rendon Nov 3 '11 at 1:00
