fi6s is a IPv6 port scanner designed to be fast. This is achieved by sending and processing raw packets asynchronously. The design and goal is pretty similar to Masscan, though it has not reached a similar feature set yet.
Building should be fairly easy IF your software is recent enough: On Ubuntu 16.04 (xenial) it looks like this:
# apt install gcc make git libpcap-dev
$ git clone https://github.com/sfan5/fi6s.git
$ cd fi6s
$ make BUILD_TYPE=release
The scanner executable will be ready in at ./fi6s.
Note that support for non-Linux OSs is not a priority,
which means that it might not work on *BSD or Windows at all.
Theoretically usage is pretty easy, however right now you need to specify adapter MACs and source IP manually.
# ./fi6s --source-mac 11:22:33:44:55:66 --router-mac 66:55:44:33:22:11 --source-ip 2001:db8::1 -p 80,8000-8100 2001:db8::/120
This example will:
- scan the 2001:db8::/120 subnet (256 addresses in total)
- scans port 80 and ports 8000 to 8100 (102 ports in total)
- outputs scan results to
stdout
There's more different ways of specifying a range of addresses to scan,
if you aren't sure what's about to happen invoke fi6s with --echo-hosts
and it will print every host that will be scanned.
For advanced features please consult the output of ./fi6s -h.
