Setting up your own gateway to the grid is beyond the scope of this write-up. It involves installing and configuring the Virtual Data Toolkit (VDT) , installing a host certificate for the gateway machine, etc. For an administrative guide see the Fermi Grid web page. |
Setting up the Environment at Fermilab
To set up the environment and to get the necessary grid proxy certificate, log onto ILCSIM and issue the following commands:
| No Format |
|---|
source /fnal/ups/grid/setup.sh
voms-proxy-init -voms ilc:/ilc/detector
# give passwd etc.
|
To check the status of the proxy:
| No Format |
|---|
voms-proxy-info -all
|

Connecting from an External Site
Kerberos Configuration
Fermilab uses Kerberos for external authentication. This section assumes that you have a Fermilab Kerberos principal. Follow these instructions if you need an account at Fermilab and are authorized to obtain one.
...
Now ssh to a gateway machine.
| No Format |
|---|
ssh USERNAME
|
You may need to use this !ssh_config! as your SSH configuration file for the Kerberos ticket forwarding to work correctly.
| No Format |
|---|
ssh -F ssh_config USERNAME@flxi02.fnal.gov |
From the node inside Fermilab, execute kinit again.
...
Provided that your local node is configured correctly, this should allow you to start a grid session on an external node outside Fermilab.
