You can setup passwordless ssh connection following this page to create an ssh key pair. Then add this block to your ~/.ssh/config file (allows to tunnel directly to iana, but you can adapt to other hosts):

Host sdfiana
  HostName iana
  User <yourusername>
  IdentityFile ~/.ssh/<your private key>
  proxycommand ssh s3dflogin.slac.stanford.edu nc %h %p
  ForwardX11 yes
  Host s3dflogin.slac.stanford.edu
