Carpal Tunnel Syndrome exercises

Tunnel HTTP over HTTP, in a structured, controllable, securable way. Let programs claim part of URL space, and serve HTTP, all by using an ordinary HTTP client library.

An interesting alternative to polling http services.

pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with *no* port forwarding and *no* DMZ setup on any routers in order to directly communicate with each other.

pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with *no* port forwarding and *no* DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect. Simply put, this is a proxy server that works behind a NAT, even when the client is behind a NAT, without any 3rd party. There is no middle man, no proxy, no 3rd party, no UPnP/STUN/ICE required, no spoofing, and no DNS tricks. More importantly, the client can then connect to any host or port on any remote host or to a fixed host and port decided by the server.

pwnat - Serverless NAT to NAT (UDP hole punching for everybody, yay)
