Can you tell if Nmap is using the correct source address and interface? Does it work if you force it with -S and -e?
I ran into a bug with the interface determination code in route_dst_netlink() somehow leaking file handles and running the box out. In short: $ sudo ./nmap --datadir . 128.54.0.0/20 Starting Nmap 5.52.IPv6.Beta2 ( http://nmap.org ) at 2011-06-13 19:49 UTC route_dst_netlink: cannot create AF_NETLINK socket: Too many open files But using a /24 works just fine. To get around this I have to specify the interface with -e. Interestingly, I only run into the issue when I use certain netblocks. For example, this works: sudo ./nmap --datadir . 132.239.0.0/20 This might have something to do with my route table having some of 132.239 in it: route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 132.239.1.112 0.0.0.0 255.255.255.240 U 0 0 0 eth6 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth3 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth4 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth5 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth7 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 132.239.1.113 0.0.0.0 UG 0 0 0 eth6 I haven't had a chance to track the issue down though. I will try some basic IPv6 tests as soon as I can make time.
