<p style="margin-top:0;margin-bottom:0">If you have 4 nodes and you know which one is sending the Interest, then you need to look into other three nodes' nfd.log. In one of the node's, which is actually serving the file, nfd.log you should be able to see something
like "received Interest /a" and "sending data for interest /a". Look for these log messages.</p>

<div>Thank you for your guide about advertise.</div>

</div>
<div>I still need to know the source of file in my simulation. In other words if for instance 4 nodes have the file f, I need to know which one is sending me the f.</div>
<div><br>
</div>
<div>I looked into nfd.log and nlsr.log but nothing seemed to be useful for me? when I use ndncatchunks in node c, nothing written in nlsr.log and nfd.log can be used to find the source of file?</div>

<div>any ideas?</div>

<br>
<div>Whatever name prefix you used to put the data in "a" using ndnpuchunks. You need to
<a href="http://named-data.net/doc/NFD/current/manpages/nfdc-route.html" class="m_4306274721106960890x_m_-7490112547941557344OWAAutoLink" id="m_4306274721106960890x_m_-7490112547941557344LPlnk630255" target="_blank">
add route</a> for that name prefix so that NFD knows where to forward Interest for this prefix. If "a" has the data, then need to add route from "b" to "a", "c" to "b", and "d" to "c".</div>
<br>
<div><span style="font-family:Calibri,Helvetica,sans-serif,Helvetica,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols;font-size:16px">Alternatively, if you are using NLSR then you can just add the
name prefix in "a" using <a href="https://named-data.net/doc/NLSR/0.4.0/manpages/nlsrc.html" class="m_4306274721106960890x_m_-7490112547941557344OWAAutoLink" id="m_4306274721106960890x_m_-7490112547941557344LPlnk322430" target="_blank">
nlsrc advertise </a>. Then nlsr will take care of the rest. If you have a large topology then this is what you should do.</span></div>

Also is there any way to understand which node is actually sending you the datapacket?</div>

<div>I don't think there is an easy way, other than to inspect the nfd.log on each node, since NDN is server agnostic.</div>
