Fragmentation and timestamp of bundles
by Leonel Gaspar Soares 16 Mar '17

16 Mar '17

I'm currently analysing bundle sending with wireshark, and I see that when a node is not a time reference, it sends bundles with timestamp 1 Jan 2000. These are accepted by another node, witch also is not a time reference. Are bundles with timestamp 1 Jan 2000 always accepted? How can fragmentation be made in ibrdtn with OpenWrt?

Convergence Layer for VHF radios
by Thomas Halwax 13 Mar '17

13 Mar '17

Hi, for my Bachelor Paper I’d like to use IBR-DTN over VHF radios. These devices have a RS-232 serial interface. I know there is a AX.25 convergence layer for DTN2. Is there something similar for IBR-DTN or do you have any suggestions? Thanks in advance, Thomas

IBRDTN between 2 nodes across the internet
by Walter L. Preuninger II 13 Mar '17

13 Mar '17

I have tried several combinations of ibrdtn.conf stanzas to get 2 hosts talking dtn, but I have not had any success. Could someone show me an example configuration for 2 hosts, routed thru the internet by tcp? I have tried with and without DHT. Thanks for any and all assistance, Walter -- Sent from Gmail Actual

Non extended API
by Maël Auzias 16 Jan '17

16 Jan '17

Hi y'all and happy new year. According to the documentation <https://www.ibr.cs.tu-bs.de/projects/ibr-dtn/apidoc/0.12/api.pdf> it is possible to "*switch to the ExtendedAPI*" to register an endpoint, send/receive bundles and so on. According to the source code there is no mention of any *APIHandler* (non Extended) yet there is a *APIServer* class and a *ApiP2PExtensionHandler* class. However these class are nothing like ExtendedApiHandler.cpp <https://github.com/ibrdtn/ibrdtn/blob/1da5501fc3fc29c52ddfe694671d5c1147a94…> file. I wonder why the command "protocol extended" is needed and what are the possible commands out of the extended protocol. Have a nice day!

05 Jan '17

Hello. I like to follow-up on this issue I'm encountering. When I executed dtninbox --quiet <name> <inbox> in my Raspberry Pi, I get the message "Aborted." It is not working. I used the --quiet option for dtnoutbox and it worked properly. What could be the problem with dtninbox? I am attaching the configuration file that I used. Thanks.

Modifying DTN key management module in IBR-DTN
by I-Rajagopalan, Vijayasarathy 03 Jan '17

03 Jan '17

Hi, a) Is it possible to plug in an alternate DTN key management module into IBR-DTN ? b) If yes, how can this be done ? Digging into the code, I understand that openssl has been used to do the key management in IBR-DTN, and this has to be modified to use the key management of our choice. I was wondering if there is an available interface to plugin the module into IBR-DTN. Regards, Vijayasarathy (Vijay) Research Engineer, Boeing Research and Technology (BR&T) India, Bangalore

Hello all, I am currently researching on routing protocols for DTN . Towards this, I may have to implement other routing protocols currently not supported in IBR-DTN. Can anyone point me to a tutorial on how to go about implementing routing protocols in IBR-DTN ? Thanks in advance, Vijayasarathy (Vijay)

However, after reading the wiki, I still don't understand very well the packages that I must install or how can budle encapsulation is made. Where can I find such information? Thank you very much.

Hello, I downloaded ibr-dtn implementation for Ubuntu 14.04 and installed it on two PCs with similar configuration. I am running dtnsend on one pc and dtnrecv on another. The bundles are accepted and the file reaches the dtnrecv. Later I run the dtnsend on the PC which was running dtnrecv and dtnrecv on the PC which was running dtnsend, I am getting Warning "*bundle rejected due to invalid authentication*" on the PC that is running dtnrecv. Can u plz help me what could be the problem or should I do any other change for the dtnrecv to accept packets. Thanks in advance -- Chaitra
