-If you are doing this on Caviness, then you would use ''caviness.hpc.udel.edu'' instead of ''darwin.hpc.udel.edu''. In addition to your standard connection settings, you'll need to set up an SSH tunnel. To do this, navigate to **Connection → SSH → Tunnels** in PuTTY. Then, add the **Source Port** to ''8787'' and the **Destination** to ''r1n17:8787'' (remember to replace ''r1n17'' with the compute node name where your interactive job is running and you started the ''rserver'' in the previous step).
