I'm testing the packet lost performance of netsniff-ng under the background
of 1Mbps ~ 100Mbps.
So, can I assume netsniff-ng runs on an embedded system?
The statistics showed by netsniff-ng is as follows (just an example, not
the real case)
7 packets incoming
7 packets passed filter
0 packets failed filter (out of space)
0.0000% packet droprate
5 sec, 278139 usec in total
My situation is that the statistics show that no packet is being dropped
(0.0000% packet droprate ),
however the amount of packets I sent and which netsniff-ng sniffer is more
that the packet netsniff-ng received (7 packet incoming).
So is there any possibilities that netsniff-ng loss the packet but not
showed by the statistics?
From the socket point of view, nothing got lost. But e.g. assuming you're using
an embedded system and it couldn't cope with such a load then, it could also be
the case that packets got dropped earlier, at the driver layer.
Are drop counts increasing for your networking device in /proc/net/dev ?
