901224_DelayTolerantNetworking : DTN at-sea test checklist This page last changed on May 15, 2012 by oreilly. ### Equipment: Laptop 'vesuvio' Manta gateway Leviton router Freewave radio ### Procedure: setup Plug VSAT cable into Leviton WAN port Plug ship network cable into Leviton LAN port Plug Manta into Zephyr router Plug vesuvio laptop into Zephyr router On vesuvio: open System Preferences -> Network; verify that Location is set to "DTN"Start ping-to-shore log verify route from vesuvio to trex (aka dtn-trex) Start ping-to-vehicle log Start ping-to-shore log Start dtnd Start dtncpd Verify satellite connection on VSAT panel; verify proper manta static address in shore.dtn.conf on odss-staging On odss-staging: Start dtnd Start dtncpd ### Procedure: during test Prior to vehicle surfacing: transfer sequentially-numbered mock mission file from shore to trex via dtncp - execute as dtnuser@odss-staging:
     dtncp --expiration 86400 ~/mydtn/outgoing/mission_n.txt dtn://trex.dtn
where 'n' is surfacing sequence number. During vehicle surfacing, verify telemetry file transfer from trex to shore - execute as dtnuser@odss-staging:
    ls ~/mydtn/incoming/trex.dtn/*.txt
Results of the above command should show files dtn_n.txt, where 'n' is the leg sequence number. Note that files grow in size for each leg, so there may be delay for large files. ### Cheat-sheet On trex and shore machine, DTN files are kept in directory ~/mydtn On vesuvio laptop, DTN stuff is in O'Reilly's account. Configuration files are in ~/mbari-dtn (which is a mercurial repository). Other DTN files (logs, etc) are in ~/mydtn. To mount Manta root filesystem as read-write:
    mount -o remount,rw /
To mount Manta root filesystem as read-only:
    mount -o remount,ro /
To add route from vesuvio to trex, execute this command on vesuvio:
    sudo route add 134.89.32.39 10.250.32.1 255.255.255.255
Satellite static addresses:
    187.125.171.144   65W - BRAZIL
    66.178.119.209    125W - CARIBBEAN
    216.245.254.64    105W - CONUS 1 & 2
    216.147.147.186   37.5W - N. ATLANTIC OCEAN REGION (NAOR)
    69.88.13.47       172E - N. PACIFIC OCEAN REGION
