https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212229 Bug ID: 212229 Summary: IP IDs generation behavior issue Product: Base System Version: 11.0-RC1 Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: jlduran@gmail.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org FreeBSD 11.0-RC1: The `net.inet.ip.random_id` sysctl does not appear to be randomizing when set to `1`. Tested on two bhyve virtual machines and using nmap. FreeBSD 11.0-RC1: $ nmap -O -v -Pn freebsd-11.0-rc1.example.com ... IP ID Sequence Generation: All zeros ... FreeBSD 10.3-RELEASE (works as expected): $ nmap -O -v -Pn freebsd-10.3-release.example.com ... IP ID Sequence Generation: Randomized ... On 10.3-RELEASE, out of the box (`net.inet.ip.random_id=3D0`) the IP IDs generation behavior was "Incremental", as stated in `inet(4)`. --=20 You are receiving this mail because: You are the assignee for the bug.=
