I have a need to
1) read all packets on a wire from eth0 2) Look at them in user space 3) Push them out unchanged to eth1 4) need to do this in both directions 5) Do not really want to have my Linux Box visible (no need for other devices to see me as a gateway, so if I sit on a trunk I am just part of the wire to the rest of the network) I know how to do do pieces of this but if somebody could fill in the blanks or correct any bad assumptions that would be a great time saver I know how to set up iptables and queue packets into user space for a single ethernet card, but I do not know how to push them out on another interface I understand to blindly get all packets I need to set my ethernet interface to promiscious mode, can this be done without assigning an IP address to the card? I assume that I will need to write some form of rules that go something like eth0 -> user space -> eth1 eth1 -> user space -> eh0 for all IP packets Can somebody help me with how to write and set up these rules , if this is even possible? Thanks in advance, willing to buy dinner certificate or some other token of appreciation for help. Art Reisman __________________________________________________ Do You Yahoo!? LAUNCH - Your Yahoo!
