Hi Junxiao,<br>
<br>
sorry to come back to you on this thing again, I know that I should
simply update my software which is outdated.<br>
<br>
Now I see a Data packet generated by ndnpoke (some software versions
and OS listed in the previous mail) that contains the following:<br>
<br>
50:fd:01:83:51:08:00:00:00:00:00:00:00:00:54:fd:01:75:06:fd:01:71:07:22<br>
<br>
which, according to your previous hypothesis, could be decoded like:<br>
<br>
50 fd // NdnlpData<br>
01 83 // ????<br>
51 08 // <font face="monospace, monospace">NdnlpSequence<br>
</font>00 00 00 00 00 00 00 00<br>
54 fd // NdnlpPayload<br>
01 75 // again ????<br>
06 fd // Data<br>
01 71 // ibid<br>
07 22 // name<br>
<br>
In addition, as you can see the 'fd' length value is never
decremented...this sound a bit weird. Any idea?<br>
<br>
Best,<br>
Salvatore<br>

Alex,<br>
<br>
the pcap is in attach. I'm not using the latest version
of the software tools and daemon, so if you either don't
see the issue or are not able to reproduce it. I'll
likely update the ndn software suite before asking you
for more support.<br>
<br>
Thanks,<br>
