Yes ;-)
Sorry, I meant I disabled the firewall on the client, maybe it was blocking the connections to the tunneled port on localhost (I think it is localhost:30000 or something). But it appears it wasn't.

It also works from ubuntu 9.04. However, I still would like to run it from my 9.10 box as this is my workstation :)
I thought it might be a firewall issue, so I tried
sudo ufw disablebut still the problem persists.jmm wrote:
I just installed a client on an old windows XP computer I had lying around, there it does work. So presumably there is something wrong with the client. No idea what that could be though.

Oops excuse me I use Ubuntu 9.10 karmic, not 9.04 as I said earlier.

Things I tried, but did not work:
- check if user is a member of "x2gousers" group in /etc/group
- check if user is a member of "fuse" group in /etc/group
- reset password of user to make sure not entering wrong password
- set DisallowTCP to false in /etc/gdm/gdm.schemas
- remove "-nolisten tcp" from /etc/X11/xinit/xserverrc
- run the command
xhost +x(from the command line it gives an error "xhost: unable to open display """ caused by no active display (and therefore no $DISPLAY environment variable), so I also tried entering this from within an VNC session and the command completed normally, also tried this with an Xvfb xsession)- allowed login with passwords in /etc/ssh/sshd_config
- restart ssh service
- restart EC2 instance
- tried installing packages x2goserver-home, x2goserver-one, x2goserver (and removed installations between trying different packages)
When I tried different NX servers, I always used the corresponding client (I have been careful not to mix up different clients with different servers). For x2goserver I am using x2goclient from the repository, I am using it on Ubuntu 9.04 desktop 64-bit edition. My settings are:
name: test hostname: <EC2 public dns here> login: ubuntu ssh port: 22 use rsa/dsa key for SSH connection: <tried different settings, tried to leave it empty, tried the key I got from amazon, tried a key which was sitting in ~/.ssh/id_rsa; tried all possibilities with and without password> session type: GNOME
In all cases the error on the server stays the same.

I've been using AMI's from Alestic or one's I build myself.
But x2go's been working solid.So you did all the normal things like change /etc/ssh/sshd_config to allow login with passwords and the user is a member of x2gousers 'group' etc

Yes, it is an Ubuntu Server AMI with ubuntu-desktop installed, the desktop is working with VNC so that part seems to have gone OK.
