Over 40 years of programming, over 20 of that in TCP/IP. Including
working on the internals of the protocol.

Sure. But that does NOT mean there are not holes in the protocol which
can be used by hackers.

Use whatever definition you want. I really don't care.

You've already proven that, Baho, by your lack of understanding. You
think RFC's are the only thing going. Sorry, Charlie. They show how
things *should work* - but don't go into what *can* be done by a hacker.

I never said the RFC's aren't real. Don't put words in my mouth.

I am not going to teach you how to hack TCP/IP.

I really don't give a damn. I have nothing to prove.

Go ahead. Keep quoting the RFC's. It continues to show how little you
understand what *can* be done.

I never said it did.

It always has been off-topic for this newsgroup.

How little you really understand.

But it's obvious - you're only arguing to argue. You're another I guess
I'm just going to have to *plonk* you again - like I did in a.w.w. You
were no more intelligent there, and we're glad you're gone.
