TODO :

1. you need to fill in the form below
2. you must read everything
3. you need to return the form by e-mail to assistance [at] medicis.polytechnique.fr with (for example as attached document) your RSA public key for SSH connection (see below)
4. we then create the required account
5. we will contact you by e-mail when it is done
6. You also got to sign this chart (not available in English) and send it to us at this adress
7. Read also the chart for RENATER.

RULES FOR GOOD USE

Security

The interactive access of the machines is limited to solely one machine "login.medicis.polytechnique.fr".

These connections NEED to be SECURE, therefore don't use the classic tools (telnet or rlogin or ftp), but tools such SSH.
Please note that no traditional Unix password is in use on MEDICIS. You need to :
- have a RSA dual-keys, generated on a Unix server by the command

                ssh-keygen

When you launch this command, we invite you strongly to choose and type a passphrase(logic equivalent of a password, which will be used to protect your dual-keys).
- send us, with this demand, your public key (by default, the ~/.ssh/identity.pubfile).

Sharing out the loading
"login.medicis.polytechnique.fr" is the only machine accessible for you. On this machine you will be able to access others with the command :

        rlogin machine or much simplier machine

The "proper" rules
In order to return to the cohabitation the easiest way is to go between the users.

• please read your e-mails which will hold all the announcements, and the word of the day of the machine "login" (/etc/motd).

• for all your problems, questions and requirements, please e-mail us at assistance [at] medicis.polytechnique.fr
• please check from time to time the space you occupy on the disk :

          cd              : to return to your home-directory
          du              : gives in Kb the space you are using
          df .            : gives the free space on the disk 
  

  A shared "scratch" space (without backup) is dedicated to large files which you could have a punctual need (like output of your jobs).
  It is accessible from the all the cluster in /scratch.
  A local "scratch" zone at each machine can be found in /scratch.local.

• check too, that there are no jobs which will run badly or without you knowing (frequent at the time of abnormal exit of the interactive software), by the command

          ps x            : on each machine
  or the best command is
          rps             : which gives you ALL the processes in the cluster
  

  If you need to eradicate the useless process :

          rlogin the_machine_where_it_turns
          ps x
          kill -9 &ltPID>
  

  Thank you for paying attention to this, in order to avoid using the CPU for no reason. Look at the loading of the machines from time to time:

        top        : permits you to see active processes on the machine
        
    

There we go, we hope that if each person pays a little attention, we can use these servers as efficiently as possible.
