Why can't I login to a cluster using SSH?
You try to login to a cluster using SSH and get an error:
> ssh della.princeton.edu
ssh_exchange_identification: Connection closed by remote host
You are probably using a wireless connection, a dormnet connection, or are connecting from off-campus.
If this is the case, you need to do one of the following:
- setup a VPN connection, and then connect to the cluster directly
- ssh to a host on the wired on-campus network (e.g., nobel.princeton.edu), and then ssh to the cluster from there
