Command line user interfaceThe user interface tools (UI) provide all commands needed to use the grid resources in a given VO. The users can either install the tools on their own machine or they can get an account on a machine provided by the user's organization or VO. The UI for VOCE runs on machine ui1.egee.cesnet.cz, account on that machine is created for each VOCE user as part of the VOCE registration process.
The VOCE UI machine can be accessed by the SSH protocol using several authentication methods:
- Password based authentication
- GSI authentication
Sources for the GSI-enabled SSH client can be found at http://grid.ncsa.uiuc.edu/ssh/, we will also provide binary versions for the main operating systems.
- Kerberos tickets
In order to use this method, a Kerberos ticket to the realm VOCE (which is an analogy to the GSI proxy) must be created by the user before accessing the UI machine. The ticket is created using the password that was chosen by an applicant during the registration stage. We also provide a simple configuration file needed to create the ticket.
Special files in your home directory at UI
contains a list of users (in the form of Kerberos principals) that are allowed to access your account. This file is generated automatically by the account management system. Please, do not remove or modify this file unless you really know what you are doing!
This directory contains your X.509 certificate and corresponding private key. Make sure that the permissions are set to 700, so you are the only user that is allowed to read the files in the directory. To check current permissions use command ls -ld ~/.globus
If you prefer using your own UI, you will need to configure it to support VOCE. A simple configuration file is provided.
