Hi Percy,
<div class=""><br class="">
</div>
<div class="">Is the script you included your entire experiment script? If not, could you please attach the full code?</div>
<div class=""><br class="">
</div>
<div class="">Right now the experiment you attached will fail with a Python error due to an undefined variable,
<font face="Menlo" class="">host</font>.</div>
<div class=""><br class="">
</div>
<div class="">You can access a specific host using the method that Shuo used:</div>
<div class=""><br class="">
</div>
<div class=""><font face="Menlo" class="">for host in self.net.hosts:</font></div>
<div class=""><font face="Menlo" class=""> if host.name == “p”:</font></div>
<div class=""><font face="Menlo" class=""> host.cmd(<span class="">"echo test1 | ndnpoke /ndn/edu/producer &”</span>)</font></div>
<div class=""><br class="">
</div>
<div class="">Or you can access a specific node using the <a href="http://self.net" class="">
self.net</a> object:</div>
<div class=""><br class="">
</div>
<div class=""> <font face="Menlo" class=""><a href="http://self.net" class="">self.net</a>['p'].cmd("echo test1 | ndnpoke /ndn/edu/p &")</font><br class="">

<div class="">Hi dear MiniNdn team<br class="">
<br class="">
I am interested in using MiniNdn for an initial basic experiment between three nodes: a consumer , a forwarder and a producer. It is highly possible that I am missing something, but the consumer is not receiving the data from the producer.
<br class="">
<br class="">
</div>
Could I ask for some advice of how this could be achieved by using MiniNdn? <br class="">
