Discovery via broadcast
by Maël Auzias 31 Jan '16

31 Jan '16

Hi y'all! Aiming to use broadcast for the discovery, the dtn daemon log: > Wed Jan 27 14:51:55 2016 DEBUG.5 IPNDAgent: can not send message to > [10.0.0.255]:4551 via [10.0.0.12]:4551 (universe)/eth0; socket exception: > 13: Permission denied but I can find where does the permission is denied from. The daemon is run as root. Any suggestion or idea on how to work around this? Is there a way to perform a static discovery (for test purposes)? Have a nice day!

UDP Convergence Layer Ignored
by Nik Ansell 31 Jan '16

Hi, I have a strange problem that I hope someone could help me with. When I use the TCP Convergence Layer, this works fine, however when I attempt to use the UDP convergence layer, it seems to remember some old configuration, or fallback to TCP and does not use the UDP convergence layer. The conf file of my source node is below: local_uri = dtn://tx net_eth_type = dgram:udp #net_internet = eth0 net_eth_interface = eth0 net_eth_port = 4556 net_interfaces = eth # Create a route to rx static1_uri = dtn://rx static1_port = 4556 static1_address = 10.0.1.3 static1_proto = udp static1_immediately = yes # connect immediately to this node #static1_global = no # this node is only reachable with internet access routing = default stats_traffic = yes api_interface = lo However, when I start the daemon: dtnd -c /home/alarm/downloads/ibr-dtn/configs/2node-udpcl/tx.conf -v -i eth0 The log shows the following entry: Sun Jan 17 21:38:50 2016 INFO NativeDaemon: TCP ConvergenceLayer added on eth0:4556 If anyone could offer any help, this would be very much appreciated! Kind Regards, Nik

Docker and IBR-DTN bleeding edge

Hi y'all! If you looking for an easy way to compile the bleeding edge source code of IBR-DTN, this Dockerfile may be useful: FROM debian:8.2 > MAINTAINER Mael Auzias <docker(a)mael.auzias.net> > LABEL Description="This image is used to run an ibrdtn daemon from Debian > 8 package with the most up-to-date source code" > RUN apt-get update && apt-get install -y \ > git tmux g++ libpth-dev make dh-autoreconf ca-certificates libicu52 > libpsl0 libssl1.0.0 openssl pkg-config \ --no-install-recommends \ > && apt-get clean \ > && rm -rf /var/lib/apt/lists/* > RUN cd \ > && git clone https://github.com/ibrdtn/ibrdtn.git \ > && cd ibrdtn/ibrcommon/ \ > && ./autogen.sh \ > && ./configure && make && make install \ > && cd ../ibrdtn/ \ > && ./autogen.sh \ > && ./configure && make && make install \ > && echo "include /usr/local/lib/*" >> /etc/ld.so.conf && ldconfig > EXPOSE 4556 > ENTRYPOINT ["/bin/bash"] You can then run $docker run --hostname nodeName -it --rm -v /tmp/dtn.conf:/dtn.conf ibrdtnbleeingedge and execute #dtnd -c /dtn.conf, add the flag --net=host if the aim is to use your host interface. Have a nice day!
