Hello Matheus,

the main problem seems to be, that your system does not seem to support multicast correctly
> Thu Jul 16 16:43:13 2015 ERROR IPNDAgent: failed to set-up multicast socket on <any>:4551: 97: cannot create socket

IPND, the protocol for neighbour discovery uses multicast. I am not sure if it is still possible, but you can try to force IPND to use a broadcast socket using this configuration option:

discovery_address = 255.255.255.255

(of course you need to do this on all nodes in your network, so they can still talk to each other)

if this does not work, you can try to disable discovery completely using

discovery_announce = 0

and for good measure for each of your defined convergence layers set discovery to no

net_wlan0_discovery = no

However, this is not ideal, because then, for nodes to see each other you need to configure them as static neighbors

Anyway, I'm on a research project on DTN, and I'm interested in using the IBR-DTN to assist me in the search. I'm using IBR-DTN program Raspberry Pi and BEAGLEBONE, both with Raspbian. It generates the output below:
