Once you have connected to the new head node, you may need to clear old ssh keys to ensure connectivity with all the new cluster nodes. The easiest way to do this is to run the following command when you have
connected:
cleanSSH.sh
SSH debug information
Should the above removal of ssh keys not work upon login, try connecting with ssh in verbose mode.
ssh -v -Y -C cluster.uit.tufts.edu
or
ssh -v -v -Y -C cluster.uit.tufts.edu
or
ssh -v -v -v -Y -C cluster.uit.tufts.edu
where each additional -v adds more detail. Usually one -v is sufficient. Login, then logout and cut-n-paste the total debug output into a mail message and send to cluster-support@tufts.edu.
