Hi,

i have question related to your answer.

1. is it true that i set ibrdtnd.conf with the following config ?

routing = none

routing_forwarding = yes

route1 = dtn://nodeC.dtn dtn://nodeB.dtn

Nearly. I think you should use dtn://nodeC.dtn/* for the regular expression to match.

2. how about ibrdtnd.conf for node B and C, what can i configure?

at node B, you can leave routing=default and routing_forwarding = yes, if you want node c to answer via node b (i.e. ping reply), then you have to add route1 = dtn://nodeA.dtn/* dtn://nodeB and also routing=none.

(beware, node names are case sensitive!)

3. i start ibrdtn using "dtnd -i wlan0", how can i start it with -v,

can you give me an example ?

sure. dtnd -i wlan0 -c /path/to/config -v

Btw, it is always the best to send the answer to the mailing list because others might have other ideas, too ;) So I added the list to CC.
