Question about network card.

Question about network card.

[Jennifer Huang]

Hi,

I am not sure if this is the correct place to ask this
question.

I wrote a traffic generator and tried to send traffic
to a linux box. I found that when I generated more
than 100Mbps traffic from multi-senders to the
receiver, tcpdump can see nothing at the receiver
side. The network card is 100Mbps. 

My questions are:

1. What will happen if there are more than 100Mbps
traffic dumped to a 100Mbps network card? Is it
possible that the card drop most of the packets?

2. Does it look like my traffic generator problem? Do
I need to set particular socket options?

Thanks,
-Jenny

You can look at /proc/net/dev to see the various network driver counters...that should
tell you something...
