Ok it seems that blobs and bundles directory needed more space. I have set in both my nodes the storage path to /overlay/TMP/bundles and /overlay/TMP/blobs.
I tried to send a 5M file.

While I was able to retrieve a 4M file, I am stuck with this segmentation fault in 5M file.
What do u think is going wrong?

Thanks,
Theodoros

If you enable the logfile options in /etc/config/ibrdtn and start the
daemon with /etc/init.d/ibrdtn start, the output will be in the log
files. If you start the daemon manually you have to enable the NOTICE
messages with "-v" to see them (see dtnd -h for more options).

$ dtnd -h
IBR-DTN version: 0.10.2
Syntax: dtnd [options]
 -h|--help       display this text
 -c <file>       set a configuration file
 -D              daemonize the process
 -k              stop the running daemon
 -p <file>       store the pid in this pidfile
 -i <interface>  interface to bind on (e.g. eth0)
 -d <level>      enable debugging and set a verbose level
 -q              enables the quiet mode (no logging to the console)
 -t <threads>    specify a number of threads for parallel event processing
 -v              be verbose - show NOTICE log messages
 --version       show version and exit
 --noapi         disable API module
 --nodiscovery   disable discovery module
 --timestamp     enables timestamps for logging instead of datetime values

Kind regards,
Johannes Morgenroth
