Similar, however the mtu is 1500. It just seems to pickup arp packets. Its
is also plugged into a switch directly connected to the internet. I started
up snort and nothing, here is the ifconfig -a

bash-2.00# ifconfig -a
lo0: flags=849<UP,LOOPBACK,RUNNING,MULTICAST> mtu 8232
        inet 127.0.0.1 netmask ff000000
hme1: flags=8c3<UP,BROADCAST,RUNNING,NOARP,MULTICAST> mtu 1500
        inet 0.0.0.0 netmask 0
        ether 8:0:20:b2:f7:e3


Here is the snort startup and summary.

David,

This should do the trick for you.....

ifconfig <interface> plumb -arp

Use the command, ifconfig -a to see if the card is
working properly. You should see an output similar to
this:

Flags=8c3<UP, BROADCAST, RUNNING, NOARP, MULTICAST>

mtu 4352

inet 0.0.0.0 netmask 0

ether 8:0:20:f0:0:ba
