# Moving between login and compute nodes

The research environments automatically configure a trust relationship between login and compute nodes in the same research environment to allow users to login between nodes via SSH without a password. This configuration allows moving quickly and easily between nodes, and simplifies running large-scale jobs that involve multiple nodes. From the command line, a user can simply use the ssh <node-name> command to login to one of the compute nodes from the login node. For example, to login to a compute node named node01 from the login node, use the command:

ssh node01

Use the command logout or exit (or press CTRL+D) to exit the compute node and return to the login node.
