dCache Hands-on

Welcome to our dCache hands-on.

Prerequisites

The virtual machines that will be used during this tutorial are SL6 machines with a kernel >= 2.6.32-220 and the following specs for the server: Minimum System Requirements. The client can have just enough disk and RAM to have the SL6 installed and running. Your client will have to have a usercertificate installed under /home/dcacheuser/.globus and the host certificate will have to be installed under /etc/grid-security on the server (students at GridKA already have user and host certificate in place on both machines)

We would like to ask every participant to bring a notebook that has an ssh client installed. Please check on your machine.

You need to login to your virtual machines (VMs). You have two VMs, one server and one client (<your number> you will get from us):

  • gks-<your client number>.desy.de
  • gks-<your server number>.desy.de

You will have to use two consoles, one for the server and one for the client. Use your ssh-client to connect to the machines using the following commands.

CLIENT:

ssh -l dcache gks-<your client number>.scc.kit.edu -p 24

SERVER:

ssh -l dcache gks-<your server number>.scc.kit.edu -p 24

After this step you should have two consoles with ssh connections to server and client. Make sure you know which console is the client, which is the server.

We also need to switch to user root on the server

[dcache@gks-<your server number> ~]$ sudo su -

Please enter the password that we gave you.

On the client please switch to user dcacheuser

[dcache@gks-<your client number> ~]$ sudo su dcacheuser -

Now we are set and ready.
