Dear Sebastian, Thank you very much, The problem already solve, I change the Api interface to Any, before I use Api interface = wlan0 because I use ad-hoc for my mesh network.

[IBR-DTN] Change Bundle Content
by Tiago Almeida 10 Nov '14

10 Nov '14

Hi, If I want to change a bundle at an intermediate node which file (.cpp) that I have to see? I’m thinking that could be the BundleReceivedEvent.cpp file. The experiment that I’m evaluate is based on three nodes, I use dtninbox and dtnoutbox to share .txt files between two nodes passing by a third one. In the middle node I want to change the bundle to add information about this intermediate node to the file that I’m transmitting. At the destination node, when I see the .txt file that I received, I expect to obtain information about the path that my bundle did. This kind on manipulation is possible? How can I do that? Thank you a lot. Best regards, Tiago Almeida

(dtnping) WARNING : TCPConnection & WARNING BundleCore

16 Oct '14

Hello, I'm trying to do a "dtnping" between two dtn nodes (node1 and node2). from node 2 : dtnping dtn://node1/echo I have noticed that they can see each other, however, when I try to make a ping from node2 to node 1, I get this warning : *WARNING: bundle rejected: bundle has expired **([415720186.377] dtn://node2.dtn/zsKZSPktexxyNvJ <dtn://node2.dtn/zsKZSPktexxyNvJ> -> dtn://node1.dtn/echo <dtn://nodeC.dtn/echo>) **WARNING: bundle has been rejected: bundle is **expired *I cannot understand the reason. Someone have an idea how may I resolve it? Thanks! Best Regards, Farouk

dtnoutbox handling of files
by Artemios G. Voyiatzis 22 Sep '14

22 Sep '14

Hi, I am trying to understand how dtnoutbox handles file deletion after it has been sent and I hope you can shed some light on this :) I am checking https://github.com/ibrdtn/ibrdtn/blob/master/ibrdtn/tools/src/dtnoutbox.cpp and some older versions of the code. I understand that dtnoutbox checks periodically a directory for changes and if it finds news files, it sends them to the destination EID. Now my questions are two: 1. Is there an option or functionality so that the files are removed (deleted) from the directory, once they are sent? If not, then they must be removed manually by another script; in that case how could be the script informed if the dtnoutbox is processing the file by the time the script tries to delete it? 2. How is the "rounds" parameter used? If the file remains unchanged after say 3 rounds, dtnoutbox will stop trying sending it? If another process adds more data in the file later on, this will go unnoticed? If it is of an any help, I am exploring how IBR-DTN can be used to build a log file (measurements) transfer mechanism over DTN; another process will be placing the log files to the outbox folder and expect to have them delivered to the collection point (dtninbox). Thank you, Artemios.

WRTnode packages
by Sebastian Schildt 19 Sep '14

19 Sep '14

I have just been playing with the nice WRTNode (http://wrtnode.com). I am happy to report, that it passed its most important test of running IBR-DTN :) If you build packages for this platform yourself, or just rebuilding the whole OpenWRT image, you will find that the current OpenWRT feeds already include recipes for IBR-DTN. However, they are not yet in the repository provided by the WRTNode guys. So for playing around, everything you need to run IBR-DTN on the WRTNode without having to build it yourself is here: https://www.ibr.cs.tu-bs.de/users/schildt/wrtnode.tar.bz2 Just install all packages with opkg MfG Sebastian

BSP and appendBlock of the Java API
by Johannes Morgenroth 18 Aug '14

18 Aug '14

Hello Maël, BSP is supported by IBR-DTN as mentioned here: http://trac.ibr.cs.tu-bs.de/project-cm-2012-ibrdtn The question in relation to the Java API I have to give back to the audience of the mailing-list, because I am not the right guy to answer that in detail. Kind regards, Johannes PS: Please direct questions of that kind to the mailing-list instead of replying to github notifications.
