[Nfd-dev] ndndump in mini-ndn

[Vince Lehman (vslehman)]

Hi Navdeep,

Could you provide the topology file, if it is different from the one below, as well as the commands you used to create the static routes? When I tried using your topology file from the other email thread, I was able to capture the ping traffic:

topology
—
[nodes]
h1: _
h2: _
g1: _
[links]
h1:g1 delay=10ms bw=100
h2:g1 delay=5ms bw=50
g1:h2 delay=10ms bw=80

commands

h1> nfdc register /ndn/nle udp4://1.0.0.2
g1> ndnpingserver /ndn/nle &
g1> ndndump –i g1-eth0 > output.txt
h1> ndnping -c 3 /ndn/nle

Hi Navdeep

I suspect ndndump is not capturing on the correct interface. The default capturing interface is the first non-loopback interface, which may be different from the interface used by experiment between traffic.

1. identify the correct interface from the output of "ip addr"
2. pass this interface as -i argument to ndndump

Yours, Junxiao

Subject: [Nfd-dev] ndn dump in mini-ndn

Hello all,

I am running ndndump on minindn topology with 3 hosts. On pinging the server I am able to get the replies but on running ndndump on hosts, nothing is coming up in the dumps.

Steps followed by me:
1.       Creating ndnpingserver g1 for content /ndn/nle
2.       Xterm g1 h1 h2
3.       On g1 running ndndump –I g1-eth0
4.       On mininet CLI – h1 ndnping –c 3 /ndn/nle
On mininet CLI I am getting content from /ndn/nle but nothing on ndndump. Please suggest if I am missing something here.

P.S. The channels I created are all UDP4


Best Regards,
Navdeep Uniyal
