ed1 is definately in promiscous mode from ifconfig. I've already got
arpwatch running on ed1. It shouldn't be, but could that be the problem?
I have 4 BPF devices in the kernel. Also the network is definately not
switched at all since we just use hubs here, but also from the large amount
if network activity and the number of packets rejected as input errors:
icarus# netstat -i
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
<sic>
ed1 1500 169.229.87/24 icarus 1118142890 827793614 16133140
817 12
65221
Would arpwatch be the problem?
