DIFI server
The DIFI server has address 192.168.253.87 on the internal department network.
It's services are remotely accessible, through port forwarding, from 130.251.168.253 by ports:
| Ext.port | Int.Port | Service |

Tasks of the DIFI server
- get analysis data from the on shore server
- get slow control data from the remote server
- transfer analysis data to the storage unit
- transfer slow control data to the storage unit
- transfer data to DIFI web server
Timing
Every action is done through crontab configuration
*/5 * * * * /home/arion/arion-update-analysis 25 14 * * * /home/arion/arion-update-slowcontrol
to look at the runnning configuration, from arion user:
crontab -l
to edit/update it:
crontab -e
Data path
Data acquired from hydrophones to on buoy Carega or Sindaco are preamplified from PreAmplifier to and to the sampled from and
The ImageMap extension is not installed.
