Hi Teng,
<div class=""><br class="">
</div>
<div class="">Can you first confirm that the file ‘/tmp/a/a.conf’ exists? If so, make sure there are no instances of NFD currently running, remove the folders for each node in the /tmp directory, and then try starting Mini-NDN again.</div>

<div class="" style="font-size: 12.8px;">Another question is how are topologies files generated, manually or by some scripts from minindn? What's the format?</div>

The topologies can be written by hand or by using the GUI. The format is described in docs/CONFIG.md (<a href="https://github.com/named-data/mini-ndn/blob/master/docs/CONFIG.md" class="">https://github.com/named-data/mini-ndn/blob/master/docs/CONFIG.md</a>),
and the GUI is explained in docs/GUI.md (<a href="https://github.com/named-data/mini-ndn/blob/master/docs/GUI.md" class="">https://github.com/named-data/mini-ndn/blob/master/docs/GUI.md</a>).<br class="">
