Before tcpdump and some mail checking
# ethtool -S eth0
NIC statistics:
     tx_packets: 3309
     rx_packets: 4672
     tx_errors: 0
     rx_errors: 0
     rx_missed: 0
     align_errors: 0
     tx_single_collisions: 0
     tx_multi_collisions: 0
     unicast: 4672
     broadcast: 0
     multicast: 0
     tx_aborted: 0
     tx_underrun: 0


After tcpdump wihout mail checking
# ethtool -S eth0
NIC statistics:
     tx_packets: 302
     rx_packets: 491
     tx_errors: 0
     rx_errors: 0
     rx_missed: 0
     align_errors: 0
     tx_single_collisions: 0
     tx_multi_collisions: 0
     unicast: 299
     broadcast: 82
     multicast: 110
     tx_aborted: 0
     tx_underrun: 0

The two dumps are attached (I hope it's what Michel wants !)
tcpdump -pw dump-eth0-promisc-off
tcpdump -w dump-eth0-promisc-on
