My connection is via SSH over PuTTY from my Win7 workstation <i>(through a VPN)</i>. When I run ./setup, the routine returns 'Can't open display'. I've enabled X11 forwarding within PuTTY, and entered "<wkstn IP addr>:0.0" in the 'X display location' blank. Also tried it with "<wkstn IP addr>:0", same result. <br><br> One popular suggestion that I've found on many pages is to enter 'xhost +' at the command line - but since this server doesn't have X installed, there is no xhost.<br><br> I've then installed Xming on my workstation, configured it as per www.nth-design.com/2010/05/19/x11-putty-xming/ precisely.<br><br>Wasn't quite sure if I had to make a corresponding change on the server, so I tried entering "export display <wkstn IP addr>:0.0" on the RHEL box, then running setup again. No luck. Also tried it with "export display <wkstn IP addr>:0", same result.<br><br>Looked around for a bit more information, found this page (http://www.doxer.org/learn-linux/use-xming-xshell-to-display-linux-gui-to-windows-desktop-x11-forwarding/) which changed the observed behavior a bit - *now* when I run setup, it pauses for maybe 20-30 seconds before returning the 'Can't open display' error <i>(which leads me to suspect that at least the server-side of the equation might be working correctly now)</i>.<br><br>The setup routine is a binary, so it's opaque to me. <br><br>X11 forwarding is enabled within the sshd_config file. /var/log/messages contains no entries from today.<br><br>The Windows firewall has an exception to allow XMing via the 'Private' network types, but *not* through domain types, so that could be an issue <i>(I'm currently unable to toggle that, suspect it's managed by either the security team or 'desktops/wkstn' team)</i>. (I've sent an email to the company directors who are emphasizing the time pressure, with any luck they'll be able to get me past *that* speed bump.)<br><br>The Xming log contains this snippet, which *seems* to indicate that it thinks that everything on my Win7 box is OK:<br><br><font face="Consolas" size="2"><span style="font-size:11pt;"><div><font color="#002060" face="Calibri">winInitMultiWindowWM - DISPLAY=127.0.0.1:0.0</font></div>
