Getting Accounts and Logging In at Fermilab

You must be on the MicroBooNE Collaboration member list in order to get an account (check if you are on it at-):
Talk to your Institutional Board representative to get on it. The IB representative from each institution is listed on that webpage.

Instructions for getting accounts:

Fermilab uses Kerberos to implement strong authentication (no passwords on the internet) when logging in to Fermilab machines.
Make sure the Fermilab KDC's are in your /etc/krb5.conf file.

Make sure your ~/.ssh/config file has default login options like the following -

ForwardX11 yes
ForwardX11Trusted yes
GSSAPIAuthentication yes
GSSAPIDelegateCredentials yes

The following example shows how to log in from a Mac with kerberos and ssh installed -

my-mac$ type kinit
kinit is /usr/bin/kinit

# case matters for FNAL.GOV, login using your Kerberos password
kinit -af -r7d <your-kerberos-principal>@FNAL.GOV 
#Note that depending on your OS, you may have -A or -a to get an address-less ticket

# this is the OpenSSH client
my-mac$ type ssh
ssh is hashed (/usr/bin/ssh) 

ssh -K
