Unable to ping android mobile from laptop
by Guilherme Rolim 24 Jun '13

24 Jun '13

Good Day, I started ibr-dtn daemon on my laptop via wifi in the same network my android mobile is connect (using ibr-dtn app). The android application manages to see the laptop as a neighbour, however, the dtnping from laptop to mobile does not work, and I couldn't test the dtn ping application (from the Dtn Example App) because it stops working. I presume that both laptop and mobile can connect with each other, right? Could anyone help me understand the source of the problem? Thanks in advance, Guilherme Rolim

Android DTN Ping
by Guilherme Rolim 24 Jun '13

24 Jun '13

Good day, I've installed the DTN Example App (DTN Ping) on my mobile, however, every time I click on the ping button it shows "DTN Ping has stopped working". I have tried on 2 mobiles already and both showed the same mistake. Has anyone ever had this kind of problem? If so, is there anyway to make it work? Thanks in advance, Guilherme

Hello Mr. Tavares, actually the best way would be to tell me the version code of the daemon like this. $ dtnd --version IBR-DTN version: 0.9.0 (build b3e6377) Assuming you are using the latest version, I need some more details about your tests. How does your script work. There are a lot of approaches to bring an interface "up" and "down". So what do you do exactly? What might happen is that your disconnection is too short for TCP to fail completely. Instead TCP would ran into several timeouts but never disrupt completely. What happens is you longer your disconnect interval to 120 seconds or some minutes?

Hello Actually the version I tested was this IBR-DTN daemon 0.9.0 (build cace11a) But I downloaded at 11-06-13 Adding information to the previous email I sent you: I use this comand to put down and up the interface : ifconfig wlan1 down ifconfig wlan1 20.0.0.250 netmask 255.255.255.0 up I am testing this with low time intervals because I want to try it in environments highly dynamic.

issue regarding transfer of files
by Bruno Tavares 12 Jun '13

12 Jun '13

Good afternoon. After several tests using ibrdtn from repository I noticed this following issue: I have two nodes in my scenario: A and B. A has a bundle of 77 MB to send to B. I have a script running on node A that puts the connection interface of that node up for 10 seconds and down for 20 seconds. In the beginning some data is transferred from A to B during those 10 seconds. In lots of the "10 seconds" intervals there is no transfer of data. I even putted the interface after some intervals up all the time and no data was transferred for lots of time. Is this a problem someone noticed? Can anyone give a little help to understand the problem. Thank you Best regards Bruno Tavares

compile ibr-dtn on openwrt
by Razvan BEURAN 28 May '13

28 May '13

Hi, I am trying to compile IBR-DTN on OpenWRT. I found out from a message on your mailing list that you have several files related to this in your SVN/GIT repository, but the link provided doesn't work anymore. Here is the message: http://www.ibr.cs.tu-bs.de/pipermail/ibr-dtn/2013-January/000278.html And here is part of its contents: > The OpenWRT packages are build from the release archives. The Makefiles > and the additional stuff for OpenWRT are available in the GIT or SVN > repository: > http://www.ibr.cs.tu-bs.de/svn/ibr-dtn/trunk/recipes/openwrt/ Could you please let me know where I can currently find the necessary files? Any related advice to compiling IBR-DTN on OpenWRT would be great. Related to this, note that I use a development OpenWRT version (r31674). I tried to install the OpenWrt packages you provided directly from the PKG files, but I had a dependency error (libstdcpp) which I didn't know how to solve, so I guess compiling is the only solution... Best wishes, Razvan
