Hi,

This is my first post so I hope I get the question out as completely as possible.

I Have an Amazon Ec2 Linux instance on which i am trying to get X11 forwarding enabled.
I have already set AllowTcpForwarding yes & X11Forwarding yes, X11DisplayOffset 10, X11UseLocalhost yes in /etc/ssh/sshd_config

I then used export DISPLAY=localhost:0.0 & also ticked the box in PuTTY where it says enable X11 Forwarding
I am still unable to connect. I am not even sure if all packages required are installed. is there anyone who has done this before who can give me a checklist of some kind or if there is a Step by Step guide that I can follow? I tried looking on the aws website but they dont seem to have any document that I can use to enable X11 (even VNC will do if thats easier to set up) I did try yum install tightvnc but it just said no such package.

My ultimate goal is to be able to install Oracle on this instance but I need to use the GUI interface to go thru the steps.

Thanks in advance

Since you say you're using PuTTY on your local machine I'm assuming it's running Windows. If that's the case then you probably don't have X installed on it. There are a few different X servers that you can use but personally I've only used the one that comes bundled with Cygwin. So, install that and start the X server (it should make sense once you install and see it) then try to connect again. Let us know how it goes.

Thanks flakblas, I am now able to use X11 forwarding. I used a tool called Xmanager & in Putty when I checked the enable X11 Forwarding, I did not fill anything in the box below it (i.e. I removed the localhost:0.0 that I had in there.
I just tested with xclock & it runs fine.
Next step... Oracle installation. Thanks so much once again.
