.bat and .sh versions do not consider same versions of *.jar files.

Class to modify: FTPCalculatorTunnel.java

Not only cleanup before new launch, also clenup after calculation is done, for confidentiality issues.

On a powerful server (say a cluster master node), we want to keep one daemon alive, and others are auto-closed when inactivity is detected. As soon as this last daemon is reserved, another one is awaked, and so on.
This will enable to use a queue manager (like slurm) without to much side efects (only the 'keep1daemon' script).

Should avoid waiting for nfs sync when reset case/new case :

Running (i/p/r/d/f/e): 95/0/4/0/0/1[Info] Blacklisting computer localhost.localdomain:44646 for 60 s. because Failed to instanciate new remote case: IOException:Unable to delete file: /SCRATCH/PROMETHEE/MATH4FLOOD/farux-login01/44646/spool/.nfs00000024000b00780000018e localhost.localdomain:44646/localhost.localdomain

By default there are 28232 ports available on system

net.ipv4.ip_local_port_range = 32768	61000

The error when creating more than limit of ports available is not explicit:

• espacer les heartbeat a plus de 5 secondes par défaut (rendre ça paramétrable dans le quota.XML)
• mais forcer un HB dès que le statut du calcul change idle<->reserved
