I'm running Ubuntu 13.04 in VM and I wanted to
do X11 forwarding to my host (Win 8), so far it works fine using PuTTY and XMing server for Windows.
But I am curious why it doesn't work if I use OpenSSH binaries (it comes together with Git for windows).
This is what I've done so far:
ssh -X
[email protected] (also tried with -Y) then gedit but received error of Cannot open display.
echo $DISPLAY came out as empty. So, I try to export DISPLAY=localhost:0.0 but it still won't work. The DISPLAY environment that I set is exactly as when it runs with Putty.
I also try changing the DISPLAY to 192.168.2.3:0.0 and other display number as well, but still it won't work.
Of course I could just use Putty to make it work, but I was wondering why OpenSSH binaries does
not work.
I have enabled all settings required in both /etc/ssh/ssh_config and /etc/ssh/sshd_config.
If I run with -v option, this is what I get
F:\SkyDrive\Projects> ssh -X -v

It seems that there is no request for X11 (I'm
not sure if there is should be one too here).
Any pointers why it doesn't work?
