What we need now are fingerprint submissions in order to start training the engine. So far it has a very small database and we need more submissions before making a release. A summary the rest of this message: 1. Update your Subversion checkout. 2. Run commands like these: # ./nmap -6 -v -O -F -e eth0 --script='targets-ipv6-*'--script-args=newtargets -oN os6-%D%T.nmap# ./nmap -6 -v -O -F scanme.nmap.org -oN os6-%D%T.nmap # ./nmap -6 -v -O ::1 -oN os6-%D%T.nmap 3. Find the IPv6 OS fingerprints, find out exactly what operating systems the targets are running, and make submissions at http://insecure.org/cgi-bin/submit.cgi?new-osSo far we've had 26 submissions! That's pretty good, even if 11 of them were from me. I would like to have about 100 for the initial database population. If you tried to do an IPv6 scan, and it didn't work, don't assume you did something wrong. It might be a bug (or something known not to be supported yet) so please send a report.I do have many IPv6 targets here in the LAN, but unfortunately the scanning was aborted after I ran the first command. The screen output is as below. # ./nmap -6 -v -O -F -e eth0 --script='targets-ipv6-*' --script-args=newtargets -oN os6-%D%T.nmap ... Completed SYN Stealth Scan at 20:43, 6.26s elapsed (6400 total ports) nmap: FPEngine.cc:2201: virtual int FPHost6::callback(const u8*, size_t, const timeval*): Assertion `time_sent.tv_sec > 0' failed. Aborted
Thanks for reporting this important information. Does this happen to you every time? Does it happen only when you scan many hosts at once? (From the output above I guess that the ping scan found 64 hosts.) I have an idea of what is causing this (there are some relevant commits in r26199:26202 and r26229:26232 in /nmap-exp/luis/nmap-os6) but I will need some time to debug it.
