<p class="MsoNormal"><span style="font-size:11.0pt">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I am trying to get a handle on automatic prefix propagation in the wild, and have three questions:
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">#1 – <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I have a testbed cert assigned for /A/B, where A=/ndn/edu/ucla and B=jburke. I am bringing up a node that I only want to publishe content, starting with a ping server, in the namespace /A/B/C.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">So first, I make a new cert for /A/B/C and sign it with my cert for /A/B. I put the cert for /A/B/C into a repo running on my node. Then, I add a route from /A/B/C to the testbed node for /A.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Given that the trust chain is set up properly, auto-prefix propagation should take care of the rest, right?
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Unfortunately, this does not work in practice unless the cert for /A/B is
<i>also installed </i>on the node publishing /A/B/C. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Is this a feature or a bug? I do not want that node to have access to my private key for /A/B, merely to be authorized by it for publishing /A/B/C. And I do not want to have to stand up a node to publish
/A/B just to get /A/B/C on the testbed. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">See a long log of how I figured out this requirement at the end of the email. (Pointers to what docs I could have read to have understood this from the start would be great.)
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">#2 – <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><u><span style="font-size:11.0pt">Why</span></u><span style="font-size:11.0pt"> must I manually register localhop/nfd, which Junxiao mentions in his article and recent emails, upon connecting to a hub for automatic prefix propagation to
work? <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Or more specifically, why is this new step explicit rather than automatic? (When would I not want it to happen? And if that’s an unlikely scenario, perhaps the more likely scenario should be default behavior?)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">#3 – <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Regarding both questions above, as a user of the testbed and NFD, where would I go to learn about these specifics, or to contribute corrections or examples as below? Right now, I think the detailed information
is distributed across some documentation, redmine issues and Junxiao’s articles, but it seems like we need a community-authored cookbook for working with the testbed, a FAQ, and/or some type of tutorial that is kept up to date as new features (like automatic
prefix propagation, cert requirements, etc. are put in place.) Would it make sense to start something like this?
