The EGEE grid infrastructure can be accessed from any Nikhef desktop running Scientific Linux 3 or 4. In order to use the EGEE gLite grid middleware, type

 . /global/ices/lcg/current/etc/profile.d/grid-env.sh        ## bash/ksh/zsh

or

 source /global/ices/lcg/current/etc/profile.d/grid-env.csh  ## csh/tcsh

first. This will set up all required environment variables for running the gLite middleware commands.


Before you can create a VOMS proxy you need to copy some VOMS configuration files first:

 mkdir ~/.glite/vomses
 cd ~/.glite/vomses
 chmod 755 .
 cp /global/ices/lcg/current/glite/etc/vomses/* .

After that, type

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

to create a voms proxy. Sample output:

 $ voms-proxy-init -voms pvier:/pvier
 Wrong ownership on file: /global/ices/lcg/glite3.0.21/glite/etc/vomses
 Expected: either (0,0) or (UID, GID) = (0, 0)
 
 Enter GRID pass phrase:
 Your identity: /O=dutchgrid/O=users/O=nikhef/CN=Some User
 Wrong ownership on file: /global/ices/lcg/glite3.0.21/glite/etc/vomses
 Expected: either (0,0) or (UID, GID) = (0, 0)

The warning

 Wrong ownership on file: /global/ices/lcg/glite3.0.21/glite/etc/vomses
 Expected: either (0,0) or (UID, GID) = (0, 0)

can be ignored. This is a feature of the voms software.
