Hi all.
Hey Jah, thanks for the report and tracking the problem down.
I've got IPv6 installed on two directly connected XP machines (this didn't need a download, it is already present and just requires installing). My router does not support IPv6, but I guess for directly connected hosts, the magic happens at layer 2. I can ping each machine from the other and capture ICMPv6 (Echo request and reply and Neighbor solicitation and advertisement) traffic with wireshark. In order to do this, I have to append the link-local interface number (so-called Zone ID) [1] to the address like so: ping fe80::20f:b5ff:fe47:7879*%6* if I don't append %6 I get "Destination *net* unreachable" from ping. If I run nmap like so: nmap -6 -n -PN -sT -d9 -p80 fe80::20f:b5ff:fe47:7879%6 I get a Reason "host-unreach" - as I do if I don't append the %6 to the nmap command. I stepped my way through the code and confirmed that I get 10065 WSAEHOSTUNREACH "No route to host". And I found that the %6 is lost during Target::GenerateIPString() in Target.cc and this seems to be down to the code in inet_ntop.c - bit vague, I know. So, have I missed something or is this something that needs doing to nbase? Has anyone else managed to use IPv6 on directly connected targets?
Hmm.. I hadn't tried this until today. I got Nmap working across the internet easily with hosts like www.kame.net, www.ipv6.org and ipv6.google.com using Teredo ("netsh interface ipv6 set teredo client"). Does this work for you? I set up another box with IPv6 on my LAN and I'm now running into the same problems with it that you are. I'll look into this more this upcoming week if nobody has any ideas.
Regards, jah
