I am no longer able to forward X11 using KiTTY/PuTTY to CygwinX.
I am connecting to an Ubuntu Server 14.10 machine that is correctly configured to allow X11 forwarding. I am able to initiate X11 forwarding using Cygwin xterm and from other linux machines.
I am using CygwinX [1.7.34(0.285/5/3)] and KiTTY 0.64.0.1 (PuTTY fork, I have also tried PuTTY), on Win7.
I have verified my display variable and have tried disabling xhost access control in Cygwin xterm.
$ echo $DISPLAY :1 $ xhost + access control disabled, clients can connect from any host
My KiTTY/PuTTY is configured to enable X11 forwarding and the correct display is set. I've tried :1 and :1.0.
When I SSH to the server my DISPLAY variable is set and xauth is updated. I have deleted my .Xauthority and recreated it to verify.
user@server:~$ echo $DISPLAY localhost:10.0 user@server:~$ xauth list server/unix:10 MIT-MAGIC-COOKIE-1 3983b2d7f3d5f9f66d9796997771bf82
When I attempt to launch an X11 application I get the following error.
user@server:~$ xterm KiTTY X11 proxy: unable to connect to forwarded X server: Network error: Connection refused xterm: Xt error: Can't open display: localhost:10.0
XWin.exe is listening on port 34576 if that matters.
[XWin.exe] TCP 127.0.0.1:34576 0.0.0.0:0 LISTENING
I believe there is a software or configuration issue I am missing as I am seeing this with multiple server and client machines. Any help would be appreciated.
