Using ssh without a password

What is kerberos ?

Kerberos is a network authentication protocol. It provides strong authentication for client/server applications so that a client can prove its identity to a server (and vice versa) across an insecure network connection. When you log in, your client contacts the Kerberos server and uses your password to prove your identity. In return it receives a ticket which is valid for 18 hours. Kerberos is about using tickets instead of passwords to get access to services running on servers.

If you are interested in finding out more, the kerberos homepage is a good place to start.

It is possible to set up self-managed machines to use kerberos with ssh to connect to DICE machines without entering a password and we strongly recommend that you do this. Below you will find step by step instructions on how to set this up on a number of platforms:
