The EGI / WLCG grid infrastructure can be accessed from any Nikhef-managed machine running a variant of Red Hat Enterprise Linux 6 (e.g. Scientific Linux 6, CentOS 6). In order to use the grid middleware tools, type

 source /cvmfs/grid.cern.ch/etc/profile.d/setup-cvmfs-ui.sh        ## bash/ksh/zsh

first. Csh users will have to first run

 /bin/bash

or perhaps even better, change their login shell to bash or zsh.

Sourcing the setup script will set up all required environment variables for running the middleware commands.

Type

 voms-proxy-init --voms <YOUR-VO>

to create a voms proxy. Sample output:

 $ voms-proxy-init -voms pvier
 Enter GRID pass phrase:

 Your proxy is valid until Fri Dec  7 00:08:49 2007

Congratulations! You are now ready to use grid middleware tools.
