                How to setup a server with secure SSH access and a centralized public key store
              
          
    Checklist


Turn off password access in /etc/ssh/sshd_config
Turn off GSS API access in /etc/ssh/sshd_config
Change AuthorizedKeysPath  in /etc/ssh/sshd_config to /ssh_keys/%u/authorized_keys
Place public keys in /ssh_keys/%u/authorized_keys

NOTE: The sysadmin needs to do this manually for every user, after the user executes ssh-copy-id


sudo chown root:root -R /ssh_keys
sudo chmod 711 /ssh_keys
sudo chmod 711 /ssh_keys/%u


## config.py
import ray
ray.init(
      plasma_directory="/PATH/TO/PLASMA/STORE",
      temp_dir="/PATH/TO/TMP/STORE",
      object_store_memory=50 * 1024 * 1024 * 1024 # 50 GB
)

# above is to avoid the `Task is a driver task and so the object created by ray.put could not be reconstructed`

# Now you can import Modin as normal
