this is my situation: there are three computerslab server (CentOS)lab personal computer(window s7)personal laptop(ubuntu)since the lab server only allowed ip address of my desktop at the lab, I was unable to establish a direct remote connection to the lab server through my laptop.So I have reached to the point where I made my lap desktop into a ssh server where now I can eventually connect to the lab server through my laptop.But the problem is that I was only able to connect to the lab server only in the CLI basis. The real deal is that I want to use the simulation programs which involves X windows stuff.After a lot of struggling, with my laptop---lab desktop----lab server connected established, I execute the simulation program through my laptop but what really happens is the simulation program is executed and displayed at the 'lab desktop'..in other words, I have failed to send the X windows display data from 'lab server' to 'my laptop'..I guess this does make sense since eventually the regardless of how further I am logged in to the lab server, the connection coming 'out' from the lab server is tunneled to my 'lab desktop'. So I guess the X display data is automatically sent to my 'lab desktop'.So I am guessing that there could be two ways to solve this:find a way that I don't know yet which will enable the X display data to be sent from the 'lab server' directly to 'my laptop'...find a way to somehow 'port forward' my lab desktop so that the incoming X display data from the lab server toward 'my laptop'...Can anyone help me in anyway on this matter??
how to 'forward' x display data?
ssh;xorg;x11;xdmcp
Try:$ ssh lab_desktop -L 2200:lab_server:22 -vvv$ ssh -Y <USERNAME>@localhost -p 2200
