Fermilab computing and submitting to Fermigrid
- You are a visitor, so apply for a visitor account here: https://fermi.service-now.com/new_acct_request.do
- You need a Fermilab contact person, this is usually an experiment spokesperson (For MicroBooNE it is currently Sam Zeller, for SBND it is Ornella Palamara)
- At the bottom of the page is a temprary password. Write this down as you need it for your first login later (at which point you should change your password)
- Mainly just sit around and wait, you will receive a large number of emails letting you know about the progress.
- To get a Fermilab services account, you have to call or go in person to the service desk (you need this for many Fermilab activities, training, etc)
- Until then, emails sent to your email address (email@example.com) are forwarded to an email address you gave them
Kerberos is the security system used by the Fermilab computing network.
- Setting up kerberos on your laptop:
- The conf file location has changed, and is dependent on OS.
- For linux, use: wget http://computing.fnal.gov/authentication/krb5conf/Linux/krb5.conf
- For MAC, use: wget http://computing.fnal.gov/authentication/krb5conf/OSX/krb5.conf
- Place this in /etc/ (WARNING: YOU SHOULD BACKUP THE krb5.conf FILE THAT IS THERE USUALLY)
- You can also set the environment variable KRB5_CONFIG to point to a specific file (if you don't have write permission for /etc, for example)
- run kinit -A username
- run ssh firstname.lastname@example.org
- where computername is something like uboonegpvm01
- if when you try to ssh you get
- Permission denied (gssapi-keyex,gssapi-with-mic). (occurs in mac OS by default)
- you have to change in /etc/ssh_config
- GSSAPIAuthentication yes
