So what is it?

Doubi is a collection of shell scripts written in Chinese, each designed to install and manage a specific network tool on a Linux server with a single command. The repository is organized as a personal toolkit for setting up proxy, relay, download, and server utility software without needing to follow lengthy manual installation steps. The proxy-related scripts cover tools like Shadowsocks, ShadowsocksR, Brook, and Mtproto Proxy, which are commonly used in China to route internet traffic through an encrypted tunnel. Each script handles installation, starting, stopping, and restarting the service, and some add extra controls like per-user speed limits, device limits, data usage caps, and automatic traffic resets on a schedule. A second group of scripts handles traffic relay and port forwarding, using tools like iptables, HAProxy, Socat, and tinyPortMapper. These let a server forward incoming connections from one port to another address, which is useful for building multi-hop proxy chains or working around blocked IP ranges. There are also scripts for torrent downloading tools such as Aria2 and Cloud Torrent, server utility scripts for enabling BBR (a network speed optimization for Linux kernels), monitoring server status, blocking spam and torrent traffic via firewall rules, and changing SSH port numbers. A VPN setup script for OpenConnect Server and a DNS tool script are included as well. The repository is aimed at people who are comfortable running commands on a Linux server but want a faster path to getting these tools running. All scripts support CentOS, Debian, and Ubuntu. The README is entirely in Chinese and serves as a reference index linking each script to external usage guides on the author's blog.
