First, make sure you’re connecting to hoek.eecis.udel.edu (CentOS) or catan.eecis.udel.edu (Ubuntu) if you have a research account, or mlb.acad.ece.udel.edu if you’re doing coursework. Connecting to Most other UNIX machines have remote SSH disabled for security - please login to either hoek, catan, or mlb before connecting to another computer.
