This is a Rust implementation of a SOCKS5 server, similar to socksyproxy.

Features:

• High concurrency via tokio
• IPv4 and IPv6 support
• Server-side DNS resolution
• ACL functionality
• Specifying bind addresses for outgoing IPv4 and IPv6 sessions
• Operational statistics via a domain socket or TCP socket
• basic SOCKS4 and SOCKS4a support (username parameter is ignored)
• will accept any username+password authentication (and log the username)

Check out example.toml for an example of what the config file looks like. You can generate the default config by running ferrous-socks --dump-config default.toml
