<p>Sorry for the delay, I have approved your request to Mini-NDN list.</p>
<p><br>
</p>
<p>Yes that is the reason - you need an entry on the node b to node a. You can do a few things:</p>
<p><br>
</p>
<p>1) Use /ndn/edu/a in your producer-consumer example as they are already registered in FIB by NLSR.</p>
<p><br>
</p>
<p>2) Register prefix via nfdc register:</p>
<p>mininet> b nfdc register /example/testApp/ udp://1.0.0.1</p>
<p>1.0.0.1 would be the IP of a, you can check:</p>
<p>mininet> a ifconfig</p>
<p><br>
</p>
<p>This method won't work if you are trying to register for more than one hop since nodes cannot reach non-neighbors in Mini-NDN - you can use NLSR for routing as in step 3:</p>
<p><br>
</p>
<p>3) Use nlsrc:</p>
<p>mininet> a nlsrc advertise /example/testApp</p>
<p>So b will automatically get the entry via NLSR.</p>
<p>This would be the easiest I think.</p>

<div class="PlainText">Good morning to all,<br>
Waiting for my request in miniNDN list, I need to ask an advice to the <br>
community, using this mailing list.<br>
<br>
I successfully installed and tried the ndnPing / ndnPingserver <br>
commands with miniNDN, and all works. Now, next step. I would like to <br>
run my personal program in the environment, byt I am having some <br>
troubles and my poor knowledge does not help me.<br>
<br>
I wrote a simple topology composed by two nodes, a and b, connected by <br>
a link. I've already used this topology for the ping experiment so I <br>
assume that it is correct.<br>
Now I would like to put in a node the program "producer" already <br>
written in the section "examples" of ndn-cxx package availaible on the <br>
git, and the "consumer" on b node.<br>
Both programs are here: <br>
<a href="https://github.com/named-data/ndn-cxx/tree/master/examples">https://github.com/named-data/ndn-cxx/tree/master/examples</a><br>
<br>
I generated the executable and I was trying to run them into a and b.<br>
The consumer start, it express its interest for the prefix <br>
/example/testApp/randomData , but after few time the timeout expires.<br>
<br>
Making some little changing in the producer, I noticed that it <br>
successfully enter into Run() function, but it does not enter neither <br>
in onInterest callback and onRegisterFailed callback.<br>
<br>
My suspicious is that the prefix /example/testApp is not registered <br>
anywhere, because I do not see it into the tables. Indeed:<br>
The FIB table of a is:<br>
/ndn/NLSR/sync nexthops={faceid=257 (cost=0), faceid=260 (cost=10)}<br>
/localhost/nfd/rib nexthops={faceid=256 (cost=0)}<br>
/ndn/NLSR/LSA nexthops={faceid=260 (cost=10)}<br>
/ndn/broadcast/KEYS nexthops={faceid=257 (cost=0), faceid=260 (cost=10)}<br>
/ndn/NLSR/LSA/edu/%C1.Router/cs/a nexthops={faceid=257 (cost=0)}<br>
/ndn/edu/%C1.Router/cs/b nexthops={faceid=260 (cost=10)}<br>
/localhost/nfd nexthops={faceid=1 (cost=0)}<br>
/localhost/nlsr nexthops={faceid=257 (cost=0)}<br>
/ndn/edu/%C1.Router/cs/a nexthops={faceid=257 (cost=0)}<br>
<br>
The FIB table of b is:<br>
/ndn/NLSR/sync nexthops={faceid=257 (cost=0), faceid=260 (cost=10)}<br>
/localhost/nfd/rib nexthops={faceid=256 (cost=0)}<br>
/ndn/NLSR/LSA nexthops={faceid=260 (cost=10)}<br>
/ndn/broadcast/KEYS nexthops={faceid=257 (cost=0), faceid=260 (cost=10)}<br>
/ndn/edu/%C1.Router/cs/b nexthops={faceid=257 (cost=0)}<br>
/ndn/edu/a nexthops={faceid=260 (cost=10)}<br>
/localhost/nfd nexthops={faceid=1 (cost=0)}<br>
/localhost/nlsr nexthops={faceid=257 (cost=0)}<br>
/ndn/edu/%C1.Router/cs/a nexthops={faceid=260 (cost=10)}<br>
/ndn/NLSR/LSA/edu/%C1.Router/cs/b nexthops={faceid=257 (cost=0)}<br>
<br>
So I am getting wrong something I think... any advice ?<br>
Thanks to all,<br>
Matteo<br>
