As root: "ifconfig eth1 up" Then start ntop as the user you want to run it as. It's fine having a mirror port with no IP address, but it must be brought up or the kernel will ignore every packet it receives. ntop will not bring the interface up for you, you have to do that for ntop. Note that you may also have to put it into promiscuous mode, depending on your kernel - that would be "ifconfig eth1 up promisc" This is a fairly basic OS function, nothing to do with ntop!
