    end

config

Create ~/.ssh/config (updating <TEXT_TO_REPLACE>):

# UCL's gateway node
Host UclSshGateway
  IdentityFile ~/.ssh/ucl_key
  User <UCL_USERNAME>
  HostName ssh-gateway.ucl.ac.uk

# UCL's Myriad HPC server
Host myriad
  IdentityFile ~/.ssh/ucl_key
  User <UCL_USERNAME>
  HostName myriad.rc.ucl.ac.uk
  proxyCommand ssh -W myriad.rc.ucl.ac.uk:22 UclSshGateway

# For ineracting with GitHub
Host github.com
  Hostname ssh.github.com
  Port 443
  IdentityFile ~/.ssh/github_key

# Store ssh key passwords securely
Host *
  AddKeysToAgent yes
  UseKeychain yes

keys

Create ssh keys, e.g. create ucl_key from above as follows:

ssh-keygen -f ~/.ssh/ucl_key

This will generate ucl_key and ucl_key.pub. The public key now needs to be uploaded to the server
