Tunneling and Forwarding Ports¶

See ALCF's Jupyter Instructions, and Tunneling and forwarding ports. The Cerebras user nodes are accessed through two steps; tunneling and port forwarding need to be through a login node. An example, that tunnels a user-started service using port 8080 on a user node to localhost:7777

export G_PORT=7777
export ALCFUserID=<your alcf username>
ssh -L $G_PORT:localhost:$G_PORT $ALCFUserID@cer-login-04.ai.alcf.anl.gov -t ssh -L $G_PORT:localhost:8080 -N cer-anl-net001-us-sr01
