TCP/IP packet repeater in the application layer

Stone is a TCP/IP packet repeater in the application layer. It repeats TCP and UDP packets from inside to outside of a firewall, or from outside to inside.

Stone has following features

  1. Simple. Stone’s source code is only 3000 lines long written in C language, so you can minimize the risk of security holes.

  2. Stone supports SSL. Using OpenSSL http//www.openssl.org/, stone can encrypt/decrypt packets.

  3. Stone is a http proxy. Stone can also be a tiny http proxy.

  4. POP -> APOP conversion. With stone and a mailer that does not support APOP, you can access to an APOP server.
