Hello,

That is strange. It really "should" work :) Maybe for better comparison, here a succesful transfer, and the corresponding commands and log messages:

SENDER Node (smokedtn):

Does this help?

Hi, Thanks for the quick response. Yeah I realized time could have been an issue, but from what I see, they both have the correct time (at least relative to each other). The output i'm getting from dtnd on the receiving node is as follows:

Tue Nov 29 17:32:18 2011 NOTICE: QueueBundleEvent: New bundle queued [375921138.53] dtn://v001/filetransfer Tue Nov 29 17:32:18 2011 NOTICE: BundleEvent: bundle [375921138.53] dtn://v001/filetransfer received Tue Nov 29 17:32:18 2011 NOTICE: BundleEvent: bundle [375921138.53] dtn://v001/filetransfer deleted

Thanks, Carson

The bundles are deletet at the RECEICING node? That would at least indicate a successful transfer. Do you have the correct time on both nodes? To be sure set them to the same timezone and use ntp to sync the clocks. You can also try increasing the lifetime of bundles, i.e. with --lifetime 7200 in dtnping will generate a bundle with 2 hours lifetime. If a suffciently long lifetime works, this would also hint at some problem with your time sync between the systems.

Otherwise: What is the exact output of the receiving node? I think normally IBR-DTN should give some hint why it deleted some bundle

Hello,

I am currently having trouble passing bundles between nodes on our system using dtnd and dtnsend or even successfully using dtnping. I have installed everything in the correct order (I believe), but dtnping and dtnsend just result in deleted bundles at the receiving node. Is there anymore documentation on how to use these programs correctly? I know they are connecting, because I can run tracepath and get the path between them, so I must be doing something else wrong.

Hi Thanks for the response, it is working now. I was forgetting to add the /echo and /filetranfer to my eids. Thank you.

The output i'm getting from dtnd on the receiving node is as follows:

To which endpoint id are you sending the bundle? Do you send it directly to the node without an application part?

e.g. dtn://abc123 is just a node. The node will drop all bundles. dtn://abc123/echo is an application which response to bundles with a copy of the bundle.

Please check if you sent your bundle to dtn://v001/filetransfer to receive it with dtnrecv.
