ssh-add gives error message: Could not open a connection to your authentication agent.

This is because your ssh-agent has stopped running for some reason and is unable to restart automatically. Try removing the file $HOME/.ssh/environment.puma on PUMA and then log out and log back in again. You will hopefully then see a message something along the lines of "re-initialising ssh-agent", you should then be able to run ssh-add successfully.
