[ipv6hackers] Difficulty with scan6

[Tim]

Hello,

I'm trying to use Fernando's IPv6 Toolkit for the first time and have
run into trouble with the scan6 tool.  I'm trying to run a simple
remote scan like this:

# scan6 -d 2600:54:b000::111:0/112 -v -v -i eth0 -s 2600:2201::a2a2:a111:b1b1:b1be 
Error while performing Neighbor Discovery for the Destination Address
Error while learning Souce Address and Next Hop


Here's what my v6 routes look like:

# ip -6 route
2600:2201::/64 dev eth0  proto kernel  metric 256  expires 2147461sec
fe80::/64 dev eth0  proto kernel  metric 256 
fe80::/64 dev tap1  proto kernel  metric 256 
fe80::/64 dev tap0  proto kernel  metric 256 
default via fe80::1 dev eth0  proto ra  metric 1024  expires 68sec



I'm able to ping6 a destination host in that remote range just fine.
Simple TCP nmap scans against the host also work fine.  What am I
doing wrong?  

I'm using the version of IPv6 Toolkit from the git repository on
a Linux host.


Thanks in advance,
tim


PS - No, the IPs above are not real, so don't try testing them
yourself.  Changed for privacy.
