Dear Ashlesh,

Thank you very much for your suggestion....now the ndnping can get the content. I use your first suggestion. However, when I try your second suggestion (using export HOME=/tmp/c) in new terminal, the ndnpingserver cannot run because error when try open some file.

Anyway, now I know why my previous attempt is failed. Thank you....

Gde Dharma

Run the pingserver in background and then check the fib:


mini-ndn> c ndnpingserver /ndn/c-site/c &> /dev/null &

mini-ndn> c nfdc fib list

mini-ndn> d ndnping -c3 /ndn/c-site/c


Or, in a new terminal you can do:

export HOME=/tmp/c

ndnpingserver /ndn/c-site/c


This way you don't have to put it in background.

(This trick can be used for any node).

Dear Junxiao,

Thank you for your suggestion. I have tried the command "c nfdc fib list". The result can be seen in the screenshot. From the screenshot, I can see the FIB of node c contain the forwarding information to other content (such as /ndn/a-site/a, /ndn/b-site/b, and /ndn/d-site/d). However, I did not find any information regarding the ndnpingserver application running on node C. I'm trying to run the ndnpingserver application in node C and then I cannot input any command after that. Any suggestion?

Regards,
Gde Dharma

Hi Gde

Is there a ndnpingserver running on C? You can confirm this by `c nfdc fib list` command.

Yours, Junxiao

Hello...

I'm newbie for mini-ndn. I already success installing the mini-ndn, however, I have some question.

1. I have run the command "a nlsrc status" (nlsrc.JPG) and "a nfdc status report" (nfdc.JPG) without error like in the screenshot in the attachment. However, when I try run "a ndnping /ndn/c-site/c -c3", the interest cannot route to the data, the result show error with reason=NoRoute (ndnping.JPG). My question, why the result of ndnping show error NoRoute?? Even there is a route in the FIB which can seen in nfdc.JPG.

2. I try to run each host using command "xterm a b c d" and the window show each terminal for host a, b, c and d. I try to run the commands ('nlsrc status" and "nfdc status report") on each terminal. However, the command gives error result: "error while connecting to the forwarder (No such file or directory). When I try to run "nfd-start" on each terminal, the command gives error result "NFD is already running..." My question, Are this error normal in current minindn??Can we ran the ndn command on separate nodes terminal?

Thank you in advance for any answer for my questions.

Regards,
Gde Dharma
