Please note that you may receive a warning that the SSH key has changed when logging for the first time to the new research cluster at clustercluster6.uit.tufts.edu.

Should the above removal of ssh keys not work upon login, try connecting with ssh in verbose mode.
ssh -v -Y -C clustercluster6.uit.tufts.edu
or
ssh -v -v -Y -C clustercluster6.uit.tufts.edu
or
ssh -v -v -v -Y -C clustercluster6.uit.tufts.edu
