It is possible to connect local ecflow_ui running on your mac/pc to the remote servers running at the center using teleport and SSH Local Port Forwarding functionality.

• First make sure you connected to the center with teleport using your token id. On the MAC i had to use latest teleport version. (5.0.0) 

  brew install teleport # *OR* > brew upgrade teleport

  
  

• Next setup port forwarding. using ma0 as an example you will need your own UID. 

  ssh -J ma0@shell.ecmwf.int ma0@polonius -C -N -L 4141:polonius:4141 -L 3142:ecflow-metab:3142

  To access cca/ccb job output , you need create a tunnel access for this as well.

  add '127.0.0.1 cca-log' alias in /etc/hosts so that connections to 'cca-log' actually go to localhost, then use

  ssh -J ma0@shell.ecmwf.int ma0@polonius -C -N -L 4141:polonius:4141 -L 3142:ecflow-metab:3142 -L 9316:cca-log:9316

  
  

• Inoke your local ecflow_ui. But please ensure you use "localhost" tunnel entrance for all remote ecflow server hostnames.
