IBR-DTN Bundle size limit
by Guilherme Rolim 03 Sep '13

03 Sep '13

Hello, I'm using the IBR-DTN service in android to share a string file that is rather big. I noticed that it sends lots of bundles in sequence and not one big bundle with all the file. Can anyone help me on how to get all theses bundles that arrive and then merge the information? Furthermore, what are the size limitations of a IBR-DTN bundle? Is there anyway to make it bigger? Thanks in advance, Guilherme Rolim

Get time and date in applications
by Dimitrios Giotas 02 Sep '13

02 Sep '13

Hello, I want to add a get time and date feature in dtnsend/recv and dtnoutbox/inbox. I think it might be useful since the 0.10.0 version doesn't display such messages in the daemon. Where can I find the application code and edit them? I have only found the executables so far. Regards, Dimitris Giotas

Is it a critical error or is it something that need not to be fixed? Regards, Dimitris Giotas

IBR-DTN configuration file
by Dimitrios Giotas 28 Aug '13

28 Aug '13

Hello, I am facing a weird problem with the ibr daemon. When I run it with a modified configuration file, both the log and the daemon itself say the active configuration file is the modified one. However, in order for the daemon to ping himself I have to use the default eid and not the one I specified in my conf file. Therefore I assume that the daemon runs in its default configuration as a whole. Moreover, I get the following message in the daemon : ERROR ApiServer: cannot bind socket with address [::1]:4550 Lastly, the daemon cannot be pinged by its neighbor, an OpenWrt router, no matter the eid I use. Any help would be greatly appreciated. Regards Dimitris Giotas

Bug report
by ssireskin＠gmail.com 26 Aug '13

26 Aug '13

Hello Johannes, I've encountered another bug in ibr-dtn. I've been sending multiple 150K-sized bundles from node 224 to node 232 via node 227 with dtnsend, when dtnd on the receiving side crashed. This behavior repeats after dtnd restart. I think the problem is somewhere in dtn client <-> dtn daemon socket communication. IBR-DTN version: 0.10.0 (build a5297f1) Please, see dtnd.log and dbg.txt in attachments. Best regards, Sergey Sireskin

Hello everyone, I am new to ibr-dtn, and the concept of dtn in general, and I have just installed the ibr-dtn daemon. I was wondering how I could get the log files of the daemon so I could examine possible future mishaps. Thank you. Regards.

Ibrdtn upgrade issues
by Dimitrios Giotas 23 Aug '13

23 Aug '13

Hello everyone, I am using ibrdtn on my two laptops and my route. I have just updated to 0.10.0 and stumbled across a couple of problems. First of all the api doesn't seem to be able to bind to the 4550 socket. To be precise, I get the error message : ERROR ApiServer: cannot bind socket with address [::]:4550 Secondly after configuring all nodes to epidemic routing, both laptops are unable to discover any nearby active nodes. Moreover they cant even ping themselves. The router however discovers and pings all nodes successfully. It seems like a brain teaser to me and I am really stuck. Any help would be greatly appreciated. Perhaps I should try a new clean install? Thank you. Regards Dimitris Giotas

ibrdtn Openwrt update
by Dimitrios Giotas 22 Aug '13

22 Aug '13

Hello, How can I update the ibrdtn daemon running on my OpenWrt router? I tried the "opkg update" but it seems that it didn't do the trick? Any ideas? Also, are there any known issues regarding the compatibility between different versions of the daemon? For example 0.8.0 and 0.10.0 Thank you. Regards Dimitris Giotas

Static routing without flood question
by ssireskin＠gmail.com 22 Aug '13

22 Aug '13

Hi Johannes and all, Is it possible to add an option to the static routing strategy, such that if it's enabled, a bundle is sent only via the first matching route, instead of all of the available routes for the bundle destination? This would avoid flooding. Best regards, Sergey Sireskin
