How to use DUNE interactive nodes


Users must have a valid kerberos ticket to access Fermilab computing at the time an attempt to log into a Fermilab machine. The ticket is obtained by executing the following command at a terminal prompt:

$ kinit principal@FNAL.GOV
where principal is the user's kerberos principal.
Enter your Kerberos password (not to be confused with your FNAL Services password). No output is good here! Ticket lifetime is 1 day. Move on to the next step.

Logging into Fermilab machines

ssh -Y -l principal
