<p>Mini-NDN first starts NFD, then NLSR, and then runs the experiment pingall. In the pingall experiment you can start tcpdump before startPctPings:</p>

<p>(An example for ndndump startup is here: <a class="moz-txt-link-freetext" href="https://redmine.named-data.net/issues/4436#note-1">

</p>
<p>If you want to start tcpdump before NFD is started then put the code in bin/minindn before NFD is started.</p>
<p>Also, once the experiment has finished you cannot invoke the convergence again from the command line. You can manually check whether they have converged similar to how it is done in

<div>Hi,<br>
</div>
<br>
</div>
When i run the default-configuration, its converged and pings fine.<br>
<br>
"sudo minindn --experiment=pingall --nPings=50"<br>
<br>
</div>
<div>But I want to capture the network packets . so i stopped (killed the nfd and nlsr process on all nodes) and started the tcpdump capture on the nodes.<br>
<br>
</div>
<div>Again, i started the nfd and nlsr process as below on all nodes,<br>
<br>
Example:<br>
mini-ndn> a nfd --config /tmp/minindn/a/nfd.conf &<br>
mini-ndn> a nlsr -f /tmp/minindn/a/nlsr.conf &<br>
<br>
</div>
<div>The process are running fine.<br>
</div>
<div><br>
But Nodes are not synchronizing/converging..<br>
<br>
</div>
<div>Am i missing some steps?<br>
<br>
</div>
<div>Note: I have not touched the configuration file.<br>
<br>
</div>
<div>Thanks<br>
