These are instructions on how to set up passwordless navigation. You can set up ssh to allow you to login to any node by making some small changes to your local ssh configuration.

Follow these simple commands (you can copy and paste them to your terminal window):

cd ~/.ssh

ssh-keygen -t dsa -N "" -C ""

cat id_dsa.pub >> authorized_keys2

chmod 640 authorized_keys2

chmod 600 id_dsa.pub

You can then transfer the id_dsa.pub file to any other computer and append it to the local authorized_keys2 file there to complete passwordless navigation.
