[IBR-DTN] " ERROR IPNDAgent: failed "
Hello guys! I'm a graduate student in Computer Science from the Federal University of Amazonas. Sorry my English, because I'm trying to translate in parallel with Google Translate. 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:

Hi Matheus,
can you please attach your configuration file?

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

Hello Sebastian and Stephan,
I'm sorry for the delay in replying. The college came into finals week and I was given a time on the project. Anyway, I wrote a configuration according to their recommendations (Attached). To make it easier for me, I decided to leave only the wlan0 interface to learn how IBRDTN works. Basically, the Raspberry Pi 2 serves as an access point for wlan0 and other devices connect to it through the wlan0 too.
When I tried to start the daemon in User mode, it featured the following message:
Wed Sep 2 04:17:55 2015 INFO NativeDaemon: IBR-DTN daemon 1.0.1-436 (build 9cdb0d9) Wed Sep 2 04:17:55 2015 INFO Configuration: Using default settings. Call with --help for options.

questions:
1 is always necessary log in as root? 2. This warning in IPNDAgent can be ignored? 3 The message that has in one instance on the site "Daemon ready" is to appear? Because here it never appears.
I wonder what I am missing so much when using this tool.
Greetings and Thanks in advance!

Hello again,
With the previous email, already solved problems. To solve the problem first, it was only to allow reading the file to the User mode. As for the problem 2, left to solve the configuration file like this:
################################################################################### # Access Point Configuration - Raspberry Pi 2
##################################### # IBR-DTN daemon # #####################################
#NAME On the spot local_uri = dtn: //RPi2.dtn
#Local To store the record logfile = /home/pi/ibrdtn.log
#define the interface for the API, choose any to bind on all interfaces api_interface = any
#Routing
routing = prophet
##################################### # Convergence layer configuration # #####################################
net_interfaces = wlan0
net_wlan0_type = tcp # we want to use the TCP protocol net_wlan0_interface = wlan00 # listen on interface wlan0 net_wlan0_port = 4556 # with port 4556 (default)
# Solution found on the site to solve the Bundle expires. time_reference = no time_discovery_announcements = yes
############################################
For now, that's all. Thank you for support. Now I try to wlan0 and wlan1.
Greetings !!
