This page gives a very brief introduction to SLAC's new S3DF (SLAC Shared Scientific Data Facility) cluster to help you get started. Note that, as of April 15 2024, onboarding involves automatic creation of both Active Directory ("windows") and unix accounts. The AD account is only useful for cyber training and logging into the Service Now ticket web portal.
For what follows, we We assume you already have a Unix account and your main intent is to run the Fermitools/Fermipy. During the transition, issues are discussed in the #s3df-migration slack channel. You can also join the #help-sdf channel if you wish to see SLAC-wide discussion of S3DF issues.
...
Basically, ssh to s3dflogin.slac.stanford.edu and from there ssh to fermi-devl (no .slac.stanford.edu; it is a load balancer, but there is only one node so far) to do actual interactive work. The login nodes are not meant for doing analysis or accessing data. Of course, real computational intensive tasks are meant for the batch system and not the interactive nodes either. Send email to s3df-help at slac.stanford.edu for issues.

Unix Password: SLAC currently requires a password change every 6 months. You can use https://unix-password.slac.stanford.edu/ to do this. Cyber Training Cyber training comes up annually. If you have an Active Directory (aka Windows) account, just follow the links. There are issues with the training system at the moment if you only have a unix account, so here is (hopefully) temporary advice on how to navigate it (note that if you got an email saying your training is coming due, the SLAC ID (SID) is embedded in the url in the email - that is the xxxxxxx in the instructions below - if your account has not been disabled, you can ssh to rhel6-64 and issue the command: res list user <your unix account name> which will give your SID (along with your account status). if none of that works, ask your SLAC Point of Contact): You need to go to the url below; DO NOT click on forgot password. Give it your system id (SID) number (xxxxxxx). Note: the interim training password is "SLACtraining2005!". If it does not work, email slac-training, asking them to reset it. Then go back to the original link, enter SID and this password. Then do CS100. https://slactraining.csod.com/ Basically, always use the SID where "user name" is requested. |

You can modify your .ssh config to allow direct passwordless access from your device to fermi-devl, by adding this to your .ssh/config file on your end: Host slac*
User <you>
Host slacl
Hostname s3dflogin.slac.stanford.edu
Host slacd
Hostname fermi-devl
ProxyJump slacl
and then add your e.g. ssh-copy-id <you>@s3dflogin.slac.stanford.edu |

For now, we are leaving the live cvs repo on nfs. The cvs client has been installed on the iana nodes. Set: CVSROOT=:ext:$<USER>@centaurusa.slac.stanford.edu:/nfs/slac/g/glast/ground/cvs |

Calibrations go to $LATCalibRoot=/sdf/group/fermi/ground/releases/calibrations/ Write access is controlled by the glast-calibs permissions group. the environment variable is set in the group profile. (Note: /sdf/data/fermi/a/ground/releases/calibrations is historical and not to be used) |

If you manage any of the unix groups from the old NFS cluster (eg glast-catalog, glast-skywatch etc), maintenance is still only available from the rhel6-64 machines, using the ypgroup command. This will change once the legacy filesystems go away. |
