<p>There is no configuration option regarding the PIT in NFD's configuration file.</p>
<p>If you want some information about the PIT you would have to add logging messages to the PIT class in NFD and compile and install it again.</p>
<p><br>
</p>
<p>1) Where to add PIT logging in NFD:</p>
<p><a href="https://github.com/named-data/NFD/blob/master/daemon/table/pit.cpp" class="m_-1769641285626669645m_-1606530918537718931OWAAutoLink" id="m_-1769641285626669645m_-1606530918537718931LPlnk582617" target="_blank">https://github.com/named-data/<wbr>NFD/blob/master/daemon/table/p<wbr>it.cpp</a><br>
</p>
<p><br>
</p>
<p>2) How to add it (from NFD developer guide: <a href="https://named-data.net/wp-content/uploads/2016/10/ndn-0021-7-nfd-developer-guide.pdf" class="m_-1769641285626669645m_-1606530918537718931OWAAutoLink" id="m_-1769641285626669645m_-1606530918537718931LPlnk928962" target="_blank">https://named-data.net/<wbr>wp-content/uploads/2016/10/ndn<wbr>-0021-7-nfd-developer-guide.<wbr>pdf</a>):</p>
<p></p>
<div>To enable NFD logging in a new module, very few actions are required from the developer:</div>
<div>• include core/logger.hpp header file </div>
<div>• declare logging module using NFD_LOG_INIT(<u></u>) macros <u></u></div>
<div><u></u>• use NFD_LOG_<u></u>(statement to log) in the source code<u></u><u></u></div>
So something like this can be added in pit.cpp:
<p></p>
<p>NFD_LOG_INIT("Pit");</p>
<p><br>
</p>
<p>3) How to turn it on in Mini-NDN:</p>
<p>In /usr/local/etc/ndn/nfd.conf (if this is not present, then<span style="font-family:Calibri,Arial,Helvetica,sans-serif,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols;font-size:16px"> /usr/local/etc/ndn/<a href="http://nfd.co">nfd.co</a><wbr>nf.sample</span>)
add:</p>
<p>Pit DEBUG</p>
<p>here: <a href="https://github.com/named-data/NFD/blob/master/nfd.conf.sample.in#L29" class="m_-1769641285626669645m_-1606530918537718931OWAAutoLink" id="m_-1769641285626669645m_-1606530918537718931LPlnk458130" target="_blank">https://github.com/named<wbr>-data/NFD/blob/master/nfd.<wbr>conf.sample.in#L29</a></p>

<p>For some reason this message got discarded by the mailing list. Did you get a Welcome message from Mini-NDN mailing list stating you can post (I don't remember if you have to confirm your subscription)?</p>
<br>
To modify NLSR conf file, look at the methods here:
<div><a href="https://github.com/named-data/mini-ndn/blob/master/ndn/nlsr.py#L166" class="m_-1769641285626669645m_-1606530918537718931OWAAutoLink" id="m_-1769641285626669645m_-1606530918537718931LPlnk187572" target="_blank">https://github.com/named-data/<wbr>mini-ndn/blob/master/ndn/nlsr.<wbr>py#L166</a><br>

If you want to change parameters in any other sections go that section method and add them in a similar way.</div>

<div dir="ltr">Dear all,
<div><br>
</div>
<div>
<div>I am beginner in using Mini-NDN emulator and have encountered problem in</div>
<div>configuration of NLSR. </div>
</div>
<div><br>
</div>
<div>
<div>I know that Mini-NDN creates for me NFD and NLSR configuration files for each node, and they are located in the /tmp/<node-name> directory. However, I need to modify some NLSR configuration parameters and I'm not sure exactly where I can do this. I tried
to edit the configuration file created in the /tmp directory, without success. I tried using the GUI to make modifications like site name or max-faces-per-prefix but none of that worked.</div>
<div><br>
</div>
<div>If anyone could help me with my problem I would be immensely grateful.</div>
