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?
