You'd be free to do whatever you want with it. I'll see I can find the source. I'm pretty sure there's a copy on my old powerbook. It was written for linux and openbsd and we used for an ad-hoc authentication method to manage a remote machine over the unsecure internet.
Never did any security auditing on the code, but I don't think there's anything wrong with it. There was one or two things that I'd like to have the time to implement, like privilege separation but that's all. But, as I said before, it is a ugly hack... :) On Thu, Nov 6, 2008 at 3:57 PM, Charlie Clark <[EMAIL PROTECTED]> wrote: > Hi Marcus, > > If you come across this program again would I be able to steal it off of > you, it will implement it as suggested before using pf state table tracking > but your program sounds very interesting and I would still like to see it. > > Thank you everyone for your answers. > > Thanks, > > Charlie > > Marcus Andree wrote: >> >> I've written a small program about 5 years ago.
