Session5 T Infr Access Emidio

  1. 1. Access to the training Infrastructure Emidio Giorgio Istituto Nazionale di Fisica Nucleare lunedì 6 luglio 2009
  2. 2. Overview • A shared t-infrastructure • Training room • Network • Support infrastructure for different technologies • access to User interface • certificates lunedì 6 luglio 2009
  3. 3. A shared training infrastructure • The school program offers a wide set of grid technologies • extremely hard to set up a different testbed for each of them • too much resources needed • many technologies have common components • too many access policies needed • much more effective to reuse common components : MultiMiddleware approach • Resources localization • client machines installed locally • server machines (resources) in remote • technologies sharing common parts (gLite, Condor, globus, UNICORE, ARC) provided from GILDA testbed lunedì 6 luglio 2009
  4. 4. Middleware co-existence in GILDA 4 lunedì 6 luglio 2009

  9. 9. Training room and local network • The training room is equipped with 20 desktop machines, where client software for some technologies have been installed on top of Ubuntu 9.04 • work in pairs • Desktop machines (aka client machines) wired, with a public IP address • issgc-client-XX.polytech.unice.fr, XX=[01,20] • client machines don't share a common area, work always with the same machine • login : user -- password : issgcuser • you can use your own laptop • SSID (hidden) is ETUD_POLYTECH (accessible also from lecture room) • Installation of technologies client software on laptops is up to you lunedì 6 luglio 2009
  10. 10. Support infrastructure for technologies • Most of the practicals will use the UI machine, where you will login via ssh (either from client machines or your laptop) • at registration time, an ID number (from 01 to 40) has been assigned to you • ui machine is issgc-ui.polytech.unice.fr • your login is issgc<ID>, password GridISS<ID> • you can change the password if you wish, but don't forget it then • At the beginning of each practical, the instructor will tell you whether you have to login on the UI or work from the client grace:~ emidio$ ssh issgc59@issgc-ui.polytech.unice.fr issgc59@issgc-ui.polytech.unice.fr's password: GridISS59 [issgc59@issgc-ui ~]$ lunedì 6 luglio 2009
  11. 11. Digital certificates • Most of technologies make use of digital certificates for user authentication • they have been provided under your area on issgc-ui, on the standard location of .globus • certificates are protected by a password : ISSGC • where needed, certificates have been authorized on technologies resources • next session will show how to request a personal certificate, that you could eventually use for practicals [issgc59@issgc-ui ~]$ ll .globus total 24 -rw-r--r-- 1 issgc59 issgc59 1773 Jun 17 11:01 ISSGC59.p12 -rw------- 1 issgc59 issgc59 1074 Jun 17 11:01 usercert.pem -r-------- 1 issgc59 issgc59 963 Jun 17 11:01 userkey.pem [issgc59@issgc-ui ~]$ lunedì 6 luglio 2009
