using x11 or freenx to connect to ASW cloud instance of CloudMan / Galaxy
Hi there, I am piloting my own instance of CloudMan in Amazon Web Services, using the current public AMI (according to your Wiki), AMI: ami-da58aab3 and Name: 861460482541/galaxy-cloudman-2011-03-22. I'd like to either tunnel X11 through SSH (either PuTTY on Windows, or just at a Linux prompt with "ssh -X"), or use an NX client to connect. I'm very familiar with how to do both, and have tested both locally. I have a local X server (latest XMing) on my Windows box, latest PuTTY, latest nomachine.com NX client. When I first start up CloudMan and login as user 'ubuntu', it asks if I would like to set up NX, and I've added myself as a user there. I can log in as that user via normal SSH connection. I can't seem to either tunnel X11 over SSH or connect w/ NX. NX connects up through the initial stage and asks me for my password, but doesn't start a desktop. Trying to tunnel X11 (xclock command) just sits forever (either via PuTTY or just normal "ssh -X" at a Linux command line). I see that Xvfb is running, and I can use 'xwd' to see an image of what is in the virtual frame buffer, ie the xclock window. It does seem like not all the required packages are installed, or possibly I just need to start a different service. Should I expect that either tunneling or NX works 'out of the box', or are there more packages I need to install and configure? Any tutorials or pointers out on the web? Thanks. I did search mail archives. :) Martin J.

Hi Martin, Xvfb is a fake display, the fact that your xclock is appearing on the virtual framebuffer rather than over your tunneled SSH connection suggests that $DISPLAY is being overwritten after you log in, or ssh is incorrectly choosing a display ID that is identical to the ID that Xvfb is using. I can't say much about NX, unfortunately, since I have never used it. --nate
