Dear Carlos,
<div class="">I do think your consumer apps set as a producer. Since there is nobody to consume that data packet, it turned out a NACK. This is my guess.

Hello,<br class="">
<br class="">
I am trying to simulate a scenario using ndn. I have just one consumer<br class="">
(node 0) and one producer (node 2). The consumer sends an interest message<br class="">
to the network and apparently the interest message arrives at the producer<br class="">
(node(2) responding with Data...). My question is why whenever this Data<br class="">
message is received by the consumer I get the log:<br class="">
<br class="">
<br class="">
*+0.000729504s 0 ndn.Consumer:OnNack(): [INFO ] NACK received for:<br class="">
/prefix/%FE%00, reason: Duplicate*<br class="">
<br class="">
Here is the complete log, as you can see, there is no other activity before<br class="">
in the network:<br class="">
<br class="">
+0.000000000s 0 ndn.Consumer:Consumer()<br class="">
+0.000000000s 2 ndn.Producer:Producer()<br class="">
+0.000000000s 0 ndn.Consumer:StartApplication()<br class="">
+0.000000000s 0 ndn.Consumer:SendPacket()<br class="">
+0.000000000s 0 ndn.Consumer:SendPacket(): [INFO ] > Interest for 0<br class="">
+0.000000000s 0 ndn.Consumer:WillSendOutInterest(): [DEBUG] Trying to add 0<br class="">
with +0.0ns. already 0 items<br class="">
+0.000000000s 2 ndn.Producer:StartApplication()<br class="">
+0.000342929s 2 ndn.Producer:OnInterest(0x2556620, 0x255f3a0)<br class="">
+0.000342929s 2 ndn.Producer:OnInterest(): [INFO ] node(2) responding with<br class="">
Data: /prefix/%FE%00<br class="">
+0.000729504s 0 ndn.Consumer:OnNack(): [INFO ] NACK received for:<br class="">
/prefix/%FE%00, reason: Duplicate<br class="">
<br class="">
Shouldn't it be something like:<br class="">
<br class="">
+0.000729504s 0 ndn.Consumer:OnData(): [INFO ] < DATA for 0<br class="">
<br class="">
Thanks so much for helping me with this issue.<br class="">
Cheers<br class="">
Carlos<br class="">
