atp: a tcp proxy

A simple TCP proxy written in rust.

why?

In the past, I had nginx set up to serve my websites, and it also served as a TCP proxy for SSH. Recently, however, I switched to Caddy for HTTPS. Caddy, unfortunately, doesn't have a TCP proxy, so I had to keep nginx around for my proxying needs. I find this a bit overkill though, which is where atp comes in.

configuration

The configuration is in the TOML format. A sample config follows:

"192.168.1.28:6667" = 8000
"192.168.1.48:1604" = 1604

running

cargo run /path/to/config.toml

If no path is provided, atp will fall back to looking for config.toml in the current directory.

TODO:

• more descriptive error messages
• use spawing + channels instead of select!
• on-the-fly config reload?
• UDP proxying?
