I want to reuse the source code of BSD's. But I am
not sure whether it is legal. Yes it has nothing
to do with OpenBSD. But I think you BSDers in this
mail list kown the answer to my question. If I can
not reuse the BSD's souce code. I will have to
rewrite a new one from scratch(I do not want to
reuse Linux's TCP/IP source code for some reason).
Anyway, thanks for your information about SFLC.
