blksocks: Black Sockets

A minimal redsocks clone in Rust.

This tool allows you to redirect any TCP connection to a SOCKS v5 proxy using your firewall.

Build

Only support Linux, not work for Mac etc.

Config

Setup log directory:

$ sudo mkdir -p /var/log/blksocks

Use chown to update its permission if blksocks run as non-root users.

The config file:

$ cat /etc/blksocks/config.toml
[network]
listen = "0.0.0.0:12345"
socks5 = "192.168.1.107:1080"

[logging]
enabled = true
file_size_limit_mb = 2
rotate_count = 5

NOTE: May need to listen on 0.0.0.0 to make tproxy system work.

Use system env TOKIO_WORKER_THREADS to config the worker count, which the default is the number of CPU cores.

$ export TOKIO_WORKER_THREADS=16
