A general security question about spoofing modern *nix operating systems, including OpenBSD. Is spoofing pretty much dead? Do modern *nix machines still use the old BSD style incrementation of sequence numbers (I don't know enough C to find it in the source)? Or are sequence numbers now random (unspoofable). Also, don't high speed LANs (gigabit, fibre) make it doubly hard to guess sequence number? I couldn't find much on the subject. Thanks.
