How to login to the T3

How to get an account and login to t3.unl.edu

We use kerberos version 5 authentication with Fermilab's KDC.
  • Request an account by sending a mail to CMS@LISTSERV.UNL.EDU with your Fermilab kerberos principal and a phone number where we can reach you to verify who you are.
  • Then you need to make sure that t3.unl.edu is known to your local kerberos client as part of the Fermilab domain. Make sure your /etc/krb5.conf file (or /Library/Preferences/edu.mit.Kerberos on Mac OS X) has the following entry in it:
    [domain_realm]
            .fnal.gov = FNAL.GOV
            .unl.edu = FNAL.GOV
    
  • Then try to login as you would to any of the Fermilab computers:
    kinit myusername
    ssh -X myusername@t3.unl.edu
    
    Again, you must be using a kerberized version of ssh and must have kerberos installed on your local node, but this should be normal practice for any FNAL user.
