Hi all,

I am trying to identify the main features of IBR-DTN overlay and what is going on beyond the basic tutorial in the website.

I have initialized two nodes running in epidemic mode (change corresponding parameter in configuration file /etc/config/ibrdtn) and i tried to send a 5M file from one to another using dtninbox/dtnoutbox.

So, @sender_node :

root@OpenWrt:~/outboxFolder# dd if=/dev/zero of=output5M bs=5M count=1

1+0 records in

1+0 records out

root@OpenWrt:~# dtnoutbox outboxSender outboxFolder/ dtn://host1/inboxReceiver

files: output5M

Killed

@Receiver_node :

Tue Feb 11 10:33:49 2014 WARNING BundleCore: bundle rejected: bundle has expired ([0.66] dtn://host2/outboxSender)

Tue Feb 11 10:33:49 2014 WARNING TCPConnection: bundle has been rejected: bundle is expired

and of course there was nothing at the inboxFolder when I typed:

root@OpenWrt:/overlay# dtninbox inboxReceiver inboxFolder/

Moreover, in order to extend router's capabilities I have performed an external root and I changed the storage option in the configuration file:

#####################################

# storage configuration #

#####################################

config 'daemon' 'storage'

# possible engines are: simple, sqlite

option engine simple

option blobs /tmp/ibrdtn/blobs

# option bundles /tmp/ibrdtn/bundles

option bundles /overlay/inboxFolder

# option container /tmp/ibrdtn/container.img

# option path /tmp/ibrdtn/container

# option limit 1G

Is there a limit in how big are the data packets?

Furthermore, is there any more extended tutorial where the parameters of the configuration file and how to change them according to our needs, are explained in more detail?

Thanks,

Theodoros
