Hello,

Me and Romeu are working on the same project with DTNs.

 
We ran the deamon with  "dtnd -i wlan2", even with an error: "ERROR IPNDAgent: join failed on wlan2; 99: setsockopt()
Thu Jan  1 00:02:02 1970" that you said we can ignore.

Then we checked that the boards are connecting, through a wireless connection.

After we had problems when we tried to follow the tutorial, we tried the dtnping, dtnsend and dtnrecv but the problem is the same for both:
-ash: dtnping: not found
-ash: dtnsend: not found

Can you understand these errors and tell us if we are doing something wrong?

Thank you in advance,
Luís Guedes
