Hi list, It appears that I have two problems when scanning IPv6 addresses from Mac OS X Lion. The first has to do with link-local addresses where I always have to add the zone index. This isn't a big problem when adding an IP or two, but when scripts add IPv6 targets or when running against some sort of list, it does become a problem. This occurs even though I specify the interface using -e. The second problem occurs when scanning "external" IPv6 addresses. What happens is that I can't scan these addresses as root (this works for link-local addresses though). The error message I'm seeing is (nexthost: failed to determine route to <ipv6 addr>). It's possible to scan the same IPv6 address as a non privileged user but as root it always fails. I've tried adding a zone index or specifying the interface with -e or forcing a TCP scan rather than a SYN scan, but the scan always fails with the same message. Anyone else seeing this on OS X Lion?

I noticed that my router (a Apple Time Capsule) is advertising it's link-local address as default gateway. Changing this manually on my OS X host to the global address fixes the problem with scanning global addresses as root. As far as I can tell from a few Google searches it seems as if Apple Airport and Time Capsule advertise their link-local address as the default gateway. To the best of my understanding this should be a valid configuration, as it seems to work for other applications ie. browsing the web etc ...
