WARNING BundleFilter: bundle rejected due to invalid authentication

When using: *$ dtnping dtn://zed1/echo* dtnd returns the following error before the echo times out: *WARNING BundleFilter: bundle rejected due to invalid authenticati**on ([0.233726701] dtn://zed0/aSreNqipcPcrKVmE)* Where zed0 is the pinging host device. The setup is two ZedBoards connected via an ethernet switch on the same subnet. Attached is my ibrdtn.conf file which is identical between the two devices with the only difference being the local node name which is zed0 or zed1. I tried explicitly setting the * security_level = 0* as well to the same effect. Thanks.

Installation problem

Hi. Is there something wrong with the repository right now? When I execute wget -O - http://jenkins.ibr.cs.tu-bs.de/download/repository.gpg.key | sudo apt-key add - , I get the following message: --2016-11-23 11:23:42-- http://jenkins.ibr.cs.tu-bs.de/download/repository.gpg.key Resolving jenkins.ibr.cs.tu-bs.de (jenkins.ibr.cs.tu-bs.de)... 134.169.35.161 Connecting to jenkins.ibr.cs.tu-bs.de (jenkins.ibr.cs.tu-bs.de)|134.169.35.161|:80... connected.

send bundles via extended api: setting bundle source to a non-default endpint
by Thomas Halwax 14 Nov '16

14 Nov '16

Hi, I use the extended API to send bundles. Let’s say I set the bundle source to "dtn://myhost/myapp/somevalue“. On the receiver side the source of the bundle is shown as „dtn://myhost/default-endpoint-id“. It’s looks like the daemon does not respect the source value of the bundle but uses the default endpoint id. Is my assumption correct? If so, why is this and is there a way to use my bundle source? My goal is to create a request-response communication but without knowing the correct sender the receiver cannot reply. Should I use the „report_to“ field for this purpose? Thanks in advance and best regards, Thomas

LowPanConnection / Sockets / Android-App / eine Erweiterung für Bluetooth
by Igor Cherepanov 07 Nov '16

07 Nov '16

Guten Tag sehr geehrtes Entwicklungsteam, das Paper [1] beschreibt LOWPANConvergenceLayer/Connection in groben Zügen, jedoch haben wir einige offene Fragen und möchten gerne wissen ob eine präzisere Beschreibung der Convergence Layer gibt, die Sie uns geben könnten. Unser Ziel ist, eine Erweiterung mit Bluetooth umzusetzen. Momentan läuft das Discovery und Connect zu den Geräten über Java, jedoch sind die Sockets für den Datenverkehr in cpp-Code [2], deswegen streben wir an, die Stelle mit den Sockets nachzuvollziehen um die für Bluetooth anpassen zu können. Leider stellt anscheinend die Android NDK keinen Zugriff zu den Bluetooth-libraries im nativen Code, haben Sie eventuell schon eine Erfahrung im Android bezüglich Bluetooth im nativen Code gemacht? Vielen Dank! [1] - IBR-DTN in IEEE 802.15.4-based wireless networks, Stefan Schmidt; ab Seite 39 [2] - in jni/ibrcommon/ibrcommon/net sind socket.cpp -> vsocket.cpp sind für den SocketState zuständig Mit freundlichen Grüßen

Raspberry Pi as bundle relay
by Dominic Solpico 03 Nov '16

03 Nov '16

Hi again. I have setup the Raspberry Pi as a wireless hotspot. At the same time, I want it to have capabilities to store, receive and send Talkie, Sharebox and Whisper files/bundles from/to other devices, particularly Android devices. Any tips on how to use the ibr-dtn applications (dtnsend, dtnreceive, dtntrigger) to be able to do this? Thanks.

Running IBR-DTN commands while dtnd is executed
by Dominic Solpico 19 Oct '16

Hello. Is there any way to start the IBR-DTN daemon using "dtnd -i eth0" without having to open another terminal or SSH client to execute other commands? I am using a default configuration file. Thanks.

IBR-DTN daemon commands

Hello. Is the difference between executing the command "dtnd -i eth0" and "/etc/init.d/ibrdtnd start"? Thanks.

Raspberry Pi dtnd
by Dominic Solpico 03 Oct '16

03 Oct '16

Hello In my Raspberry Pi command line (via SSH), when I execute dtnd -i eth0, the console gets stuck to: "INFO NativeDaemon: Using default routing extensions" It does not proceed to the messages from "INFO DTNEngine: Forwarding of bundles enabled." to "INFO DTNEngine: daemon ready" I had to open another terminal to try to execute other commands to the Raspberry Pi. Also, when I execute dtnping to other devices, I still get a timeout. What could be the problem in the Raspberry Pi? Thanks. Dom

IBR-DTN in Raspberry Pi not discoverable
by Dominic Solpico 29 Sep '16

29 Sep '16

Hello, I was able to install IBR-DTN v1.0.1 in a Raspberry Pi 2 Model B with Raspbian Jessie. In addition to the instruction followed, I added the line deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi to the sources.list since libarchive12 is not available in the Jessie repository. I also installed in an Android phone and Windows desktop IBR-DTN (and Whisper, Sharebox and Talkie in Android). I get timeout messages when executing dtnping and discovering peers. The following are the problems I encounter: 1. dtnping from Raspberry Pi (via SSH) to Android phone or the Windows PC - I get Timeout message from both. IBR-DTN daemon is running. 2. Windows PC to Android and Rasperry Pi - also Timeout message from both 3. In Android, Windows PC is in peer list but not Raspberry Pi (in logs, there is also the message connection to dtn://<WindowsPC id> failed) Attached are the log files from Windows PC and Raspberry Pi and Android phone. Is there anything I should change in the Raspberry Pi configuration? I appreciate any help. Thanks. Dom
