Apparently the decision was made to do it this way because it simplified the fast path of the code; but I could be wrong. I have yet to achieve Linux Guru status, right now I'm just some guy who has hit this problem and knows the work-arounds. > If I screw up and put it on the wrong card, I WANT the system to stop > working... I agree. I'm not making an argument for this implementation. Well, maybe I am; Linux is intended as a desktop operating system and in that context most people would rather have the failsafe than the failstop. Perhaps this method is `inelegant' but it kept up a cluster of machines we have here a lot longer than they might otherwise have functioned (the gige Acenic driver had some problems a while back and about half the cards silently failed-- the 'broken' arp responses meant that we could still talk to those boxes without reconfiguring IPs). Anyway, Here's links to a discussion that occurred this January. If you require the 'hidden' functionality, the first message cites the following links; the patch apparently works with 2.4.x with some tweaking. http://www.linuxvirtualserver.org/arp.html http://www.linuxvirtualserver.org/hidden-2.3.41-1.diff http://www.uwsg.indiana.edu/hypermail/linux/kernel/0101.3/0014.html http://www.uwsg.indiana.edu/hypermail/linux/kernel/0101.3/0020.html http://www.uwsg.indiana.edu/hypermail/linux/kernel/0101.3/0188.html http://www.uwsg.indiana.edu/hypermail/linux/kernel/0101.3/0213.html http://www.uwsg.indiana.edu/hypermail/linux/kernel/0101.3/0220.html http://www.uwsg.indiana.edu/hypermail/linux/kernel/0101.3/0268.html http://www.uwsg.indiana.edu/hypermail/linux/kernel/0101.3/0334.html http://www.uwsg.indiana.edu/hypermail/linux/kernel/0101.3/0410.html Hope that helps -Eric -------------------------------------------- Eric H.
