HellasGrid - The User Interface and how to gain access

From EGEE-see WIki

A User Interface is nothing more and nothing less than a Linux box having installed all the required client software, APIs and tools for developing and running applications in the Grid. In practice everyone can install and setup a UI with the required EGEE tools following the instructions in the GLITE-3 Installation Guide.

Also the Italian SA1 EGEE Activity has made available a package called UIPnP which can be installed in any Linux machine and turn it into a User Interface (you can even install it as a regular non-root user). Note though that it is preconfigured for accessing the Italian EGEE sites and some manual configuration steps are required at the moment in order to be useful for EGEE-SEE users (for instructions see How to customize UIPnP for SEE-VO).

There is also a chance that your institute may already have setup a UI machine so you can ask from your local administrator to create an account for you there.

Till now, six User Interfaces has been installed to serve the HellasGrid users:


  • three in Athens (ui01.isabella.grnet.gr, ui02.isabella.grnet.gr, ui01.marie.hellasgrid.gr),
  • one in Thessaloniki (ui01.afroditi.hellasgrid.gr),
  • one in Heraklion (ui01.ariagni.hellasgrid.gr) and
  • one in Patras (ui01.kallisto.hellasgrid.gr).


You can request access to the appropiate UI according to the location of your organization by following the second choice at the web page https://access.hellasgrid.gr/. If you do not have access to a User Interface or you cannot (or do not want to) install your own UI, you may request via the web page https://access.hellasgrid.gr/ for an account at the Isabella catch-all UI hosted in the GRNET site, which is located at Athens; provided of course that you have already obtained a digital certificate issued by the HellasGrid-CA. In order to connect at the User Interface at which you have an account you must use an ssh client program, for example putty, a free program which can be downloaded from the link http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html.
