Here is the situation :
1. I have a Linux server sitting in IP A
2. After watching the number of incoming traffic into ethernet0 (IP A), I found it's increased about 2 MBytes every 5 minutes.
3. Then I run a network sniffer, and I found 2 IPs ... broadcasting something into a broadcast address and to a multicast address.
My question, is broadcast traffic affecting network load on my server ?
