Translations:SSH tunnelling/26/en

SSH tunnelling can also be used in our context to allow a user's computer to connect to a compute node on a cluster through an encrypted tunnel that is routed via the login node of this cluster. This technique allows graphical output of applications like a Jupyter Notebook or visualization software to be displayed transparently on the user's local workstation even while they are running on a cluster's compute node. When connecting to a database server where the connection is only possible through the head node, SSH tunnelling can be used to bind an external port to the database server.
