For ssh connections this procedure is not required, as X-forwarding for ssh is enabled by default in /etc/ssh_config, so you don't even have to add a "-X" command-line parameter
- For any other cases, authorise incoming X connections to your workstation first:
$ xhost +
- Then, find out your display port:
$ env | grep DISPLAY
- For instance, an output of DISPLAY=":100" means that your display port is 100 (which is the default)
And, finally, in the remote machine, indicate your display port:
$ export DISPLAY=<vm-name>.ecmwf.int:<display_port>
For example
$ export DISPLAY=c8-beta-001.ecmwf.int:100 $ run_my_gui_application
- After you have finished, always remember to disable incoming connections again:
$ xhost -
