[Ndn-interest] Request for help with running ndnping and ndnpingserver on our testbed

[Lan Wang (lanwang)]

How do you know the routes are correctly set up?  Can you show a screenshot of the nfd FIB on node 1?

Dear Members of the community,

My team is working on setting up a testbed that runs on NDN. The testbed consists of 5 Raspberry Pi-4 devices all connected to an L2 switch(D-Link Switch DGS-1250-28X) via ethernet and this switch is connected to a private network. The R-Pi devices each run Ubuntu Server 22.04.03 LTS and all of them have NFD, ndn-cxx and ndn-tools installed along with their dependencies and the steps mentioned in the respective github repositories of NDN. I was able to successfully run the producer-consumer example on all our R-Pi devices.

When I decided to test out the connectivity of two R-Pi devices in this setup over NDN, I tried running ndnping server on one device and ndnping on the other which is not working. I followed the steps mentioned here<https://github.com/named-data/ndn-tools/tree/master/tools/ping> on the ndn-tools documentation on github. I have made sure to add the respective interfaces and routes (using nfdc face create and nfdc route add, while using udp4) and also made sure that NFD is running properly. We do not understand what is the issue here and we could really use some help.

I have attached the screenshots of the terminal from testing the ndnping and ndnpingserver commands. Please write to us if you need any more clarifications on our issue.

Thanks,
Navaneet
