<p>2) PIT is not printed or logged currently. It is planned to be logged in future but cannot say when.</p>
<p> You can modify PIT related files here: <a href="https://github.com/named-data/NFD/tree/master/daemon/table" class="x_OWAAutoLink" id="LPlnk897835">https://github.com/named-data/NFD/tree/master/daemon/table</a></p>
<p> and add some logging.</p>
<p><br>
</p>
<p>3) Just have a 3 node topology.</p>
<p> a----b----c</p>
<p> NFD and NLSR runs on each node by default.</p>
<p> Use NLSR on a to advertise your route to the network:</p>
<p> mininet> a nlsrc advertise /sample</p>
<p> </p>
<p> Then run consumer on 'a' and producer on 'c'.</p>
<p><br>
</p>
<p> If you don't want to use NLSR. You would have to create a route on 'b' using the route command so that 'a' can reach 'c'. Then you can use nfdc register to register a prefix towards c from a. In Mini-NDN a node can only reach its neighbors.</p>

<div class="PlainText">Good morning at all and thank you again for the help that I am
<br>
receiving by your community.<br>
I spent some time, without success, in trying to print the following <br>
information (I am working in miniNDN:<br>
<br>
1) The Content of the Data.<br>
If I print the packet, I obtain:<br>
Name: /mat/try/normandie/%FC%00%05%3CO%E0%D0%FC%D7<br>
MetaInfo: ContentType: 0, FreshnessPeriod: 10000 milliseconds<br>
Content: (size: 6)<br>
Signature: (type: 1, value_length: 256)<br>
<br>
So I manage to play with the blocks and the buffers, but the <br>
documentation is not really verbose. However, I though to write:<br>
<br>
void onData(const Interest& interest, const Data& data) {<br>
log << "Data received correctly" << std::endl;<br>
log << data << endl;<br>
<br>
//take block<br>
ndn::Block x = data.getContent();<br>
<br>
//take buffer<br>
shared_ptr<const Buffer> buffer = x.getBuffer();<br>
<br>
//take string<br>
std::string content((char*)buffer.get(), 6);<br>
log << content << endl;<br>
}<br>
<br>
But on my log file I obtained just not-printable random characters! <br>
Where did I wrong?<br>
<br>
2) the PIT table of a node. I did not find any with nfd-status and <br>
other commands. Is it possible in principle ?<br>
<br>
3) Finallyh, I would like to concentrate here another question a bit <br>
different. Working with miniNDN, I would like to build the following <br>
topology:<br>
Consume <-------> gateway <-------> Producer.<br>
I already wrote my version of consumer and producer, with the callback <br>
onInterest, onData etc.. But with the gateway, conceptually how should <br>
I structure the program that works on this node?<br>
<br>
Thank you for you help, I say it again it so I will not fill up the <br>
mailing list with just "thank you" answers :)<br>
