Here is the set-up to make it work :
We’ll have to set up a reverse ssh forwarding for the tile-monitor to connect to our tile-eclipse instead of trying to connect to some local listener on the remote host.
ssh -R 34531:localhost:34531 sauron.run.montefiore.ulg.ac.be
Where in our case, the port 34531 is the one you found in tile-eclipse, and sauron.run.montefiore.ulg.ac.be is our host where the tile is connected.
Each time you re-run tile-eclipse you’ll have to redo that part as the port will change.
Then only once you have to set up your run configuration.
I never found a better way to set it up (not using myself a ssh -R reverse forwarding), it should be possible to set it up automatically.
