<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should simply update my software which is outdated.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 // </span><span
style="font-size:12.0pt;font-family:"Courier New"">NdnlpSequence<br>
</span><span
style="font-size:12.0pt;font-family:"Times New
Roman",serif">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</span><span
