20:17:03 bonsaiviking $ <ketilmore6> turns out the nmap -p 1-65000 was finding open ports by accident because source port sometimes was equal to destination port. (birthday paradox) 20:17:07 bonsaiviking $ wtf 20:18:58 bonsaiviking $ confirmed on svn r32703 20:19:31 bonsaiviking $ but only with -sT
I just thought of solution - perhaps we should connect again to a port that seems to be open to get a different ephemeral port? If it's closed this time, we know that it was probably a false positive.
