Regarding OpenWRT the "uci" systemis used for configuration, You can find that configuration file in /etc/config . This will be converted to a config file in ibrdtn syntax when the dameon is started. So if you are unsure, you can check /tmp/ibrdtn.config while the daemon is running to see which configuration is really used by an OpenWRT node.

The DHT module allows to look up EIDs of other DTN nodes, if they are also suing DHT and have a direct internet connection. See this paper for details:

Hello,

I'm struggling with a weird fact, I can not ping from one dtn node(C) to another dtn node (A), and I cannot understand completely why. I have set the right clocks and the configuration but first I have to ping (dtnping) from A to C in order that C can ping A, if I start directly pinging from C to A the nodes cannot see each other. Indeed, looking at the log of C there aren't other dtn nodes present... The discovery_announce are set on C but I don't know how to check whether it's enabled on A (this node uses openwrt). Any hint of what's going on?

Furthermore, I would like to know the functionality of DHT package, what is it used for?

Thanks in advance,

Ragards!
