[vox-tech] How do I make SSH connect anyway if a host's IP has changed?

[Mark K. Kim]

You should SSH to a specific host, such as king.ece.ucdavis.edu,
cobra.ece.ucdavis.edu, asp.ece.ucdavis.edu, etc.

Making the host ignore the key is a security risk and shouldn't be done.

ISUN has a different system where each host has the same key.  I guess
it's a hassle to set up all the hosts to have the same key.  I think ISUN
has a significantly less number of systems to manage.
