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
