export DISPLAY and SSH -X (neither work)

Can't figure this out. I have a new install, and everything seems to be working fine except for this.

I do xhost +, and then try to do export DISPLAY=mynode:0.0 from another machine, but it always says "can't open display".
I also try SSH -X to forward xpackets, but the same error is returned. I have uncommented the "X11 Forwarding yes" line in the ssh_config and sshd_config (and restarted). Still no love.

Any suggestions?

Yep - that worked, thanks!

Now to figure out why SSH -X doesn't work.

For ssh -X check your /etc/ssh/ssh_config on the client and /etc/ssh/sshd_config on the server for ForwardX11 yes and X11Forwarding yes respectively.

yes, as per before, I set that in both config files, and it still doesn't work.

EDIT: I re-emerged openssh. Now, I get:

You might try the following ... I have had to use it on occasion for running certain opengl base programs.
