Well, initially I was just curious. As the name implies, it's a TCP proxy, and different features could go into that.
I looked at for example port knocking for hindering unauthorized access to the (protected) TCP service SMPS, but there you also have the possibility of someone eavesdropping, and learning the right handshake, if you will. So it's something that will work, until someone gets determined to make a mess. In short, it will give better control than backlog does, enabling Python-style code and logic to deal with different situations. I was about to say "deal with things intelligently"; but I think "intelligent" is a word that doesn't fit here or in many other applications. Say for example this service comes under attack for unknown reasons; it could be possible to teach the proxy to only accept connections to the backend server for IP addresses / subnets that have previously n number of transmissions back and forth. If you know that the service will have max 50 different clients. Anyway, what Chris said earlier, I think we can file that under "eagerness to tech others and show what you know". Right Chris? :) Regards, Morten On Sat, Jul 30, 2022 at 10:31 PM Barry <ba...@barrys-emacs.org> wrote: > > > > > On 30 Jul 2022, at 20:33, Morten W.
