Hi, i'm the author of zcip. It hasn't received very extensive testing yet, though it works fine for us internally and i've verified interoperability with a bunch of flavors of Windows. zcip should work just fine on a network with a dhcp server, that's how i do most of my testing. (Of course if there's a dhcp server you're probably better off using that to get your IP configuration.) To help me debug the problem you're having, please run the following commands and mail me all of the output: ifconfig route zcip I also need to see a packet trace of zcip running, ie run "tcpdump -l -n" before starting zcip, and mail me the output of that, too. We'll get you going!

The questions are about how the IETF draft is supposed to be implemented, so this is at least partly on-topic. These questions are against the zcip-1 code that I recently got off a kernel.org mirror. They may not represent the current state of the code Q1. The zcip code doesn't support multi-homing (aka IP aliasing, having more than one virtual interface (including IP) on a single physical network device yet, but I'd like to make it work in the near future. Which of the section 3 choices (link local on one interface, shared link-local address, unique link-local address on all interfaces) is expected? Q2. I am worried about existing interoperability problems. Is it expected that major vendors (especially Microsoft) will release service packs or patches to ensure conformance? Or is it worth adding a non-default option to defend more agressively? C1. For people who tried running zcip-1, and had the "infinite fast loop" problem, where zcip seemed to find immediate conflicts on every address, you need to configure your kernel to support packet filtering (CONFIG_FILTER) in the networking options area. Then rebuild. Vendor kernels seem to have this turned on, and Linus kernels have it turned off. R1. Could the author of zcip get in contact with me? I have a patch adding documentation and some minor code changes that I'd like to get incorporated.

See figures 1 and 2. Mea culpa :-(. Ignore the multi-home reference, and go with the "having more than one virtual interface (including IP) on a single physical network device" description. > I assume you're talking about the W2K/WXP aggressive claim behavior? > It would probably make sense to observe a pair of W2K/WXP hosts collide > and see how they defend the claim, then add a flag to mimic that behavior. I only know of it from your README, but am philosphically opposed to having anyone beat up on my Linux box :-) Patch provided off-list. Thanks for the fast response!
