Hi Matteo, I suggest:
1. Check the server's debug output for any X11-related messages. (See http://grid.ncsa.illinois.edu/ssh/ts_server.html for instructions.) You may find an error related to xauth indicating that you need to pass a ./configure --with-xauth option when compiling from source. 2. Do you see the same problem using server binaries from Globus or do you only see the problem when compiling the server from source? 3. Do you see the same problem using our latest GSI-OpenSSH pre-release from https://github.com/globus/gsi-openssh/releases? Any help testing our pre-release is much appreciated. -Jim On 1/25/16, 5:53 AM, Lanati, Matteo wrote: >Hi all, > >I¹ve a gsissh server compiled from sources version 6.0.1433516164. >In the config file of the daemon I set ŒX11Forwarding' to Œyes'. >However, when I connect from my machine and I try to start a graphical >application, I get the following error > >xterm Xt error: Can't open display: >xterm: DISPLAY is not set > >If I set the variable, (i.e., connecting via ssh and getting a display), >things work as expected. >The daemon is using the correct config file, since in the verbose output >of the client I see > >X11 forwarding request accepted on channel 0 > >while, if the X11Forwarding option were disabled, I¹d expect the message >"X11 forwarding request failed on channel 0². >The behaviour doesn¹t depend on the client platform, I tested it on OSX >and on Debian (both Globus 6, precompiled from the official repository). >Are there further suggestions? >Thanks in advance, > >Matteo
