Repository Details

A lightweight proxy client written in C, intends to support multiple protocols(trojan etc.)

pegasocks Cirrus CI Build Status

is a (socks5)proxy client written in C, intended to support multiple types of proxy protocols(trojan, v2ray, *shadowsock, ..). It is lightweight and supports unix-like systems(Linux/WSL/BSDs/OSX).

⚠️ This project is under development, please consider the cost and risk of use at your own discretion.

Features

Unlike most other clients that support multiple protocols, pegasocks does not rely on various third-party cores (e.g. v2ray-core, etc.), but really goes for the disassembly of the relevant protocols and takes care of performance as much as possible. Therefore it

  1. 🍃 is light enough that there are no QT or boost or other third-party binary dependencies.
  2. 🚀 Performance-first, with multiple worker threads by default, so theoretically higher throughput to be benchmarked)
  3. 🚥 This is a learn by doing project, feel free to review the code, provide optimization ideas and C programming related guidance.
  4. ❌ There is no GUI, you can directly work with systemd, launchd, rc or various custom scripts toconfigure the bootu.But you can optianly choose to build a simple tray indicator to interact with it, but in short, a heavy-duty GUI is not under consideration.

Dependencies

  • openssl 1.1.1 / mbedtls 2.27.0
  • libevent2.12 (on OSX, need the latest version)
  • pcre (lagacy) optional,will need it when ACL is enabled

Other dependencies are managed through git submodule, so you need to run following command after git clone.

git submodule update --init

Or add --recursive parameter in git clone command.

Install

If you use Arch Linux, you can install the latest version via AUR

yay -S pegasocks-git --overwrite /usr/local/bin/pegas,/usr/local/share/pegasocks/*

Or you can build it yourself as following

Build

mkdir build && cd build

cmake -DCMAKE_BUILD_TYPE=Release -DWITH_ACL=ON -DUSE_JEMALLOC=ON .. && make

Cmake Options

option meaning default
-DUSE_MBEDTLS Whether to use mbedtls instead of openssl OFF
-DUSE_JEMALLOC Whether to use jemalloc OFF
-DUSE_STATIC Whether to use static links OFF
-DWITH_ACL Whether to open ACL support (this will use more dependencies( libcork/ipset/PCRE ), so it will increase the final size of the program) OFF
-DWITH_APPLET Whether to enable system tray support (this will depend on some system libraries and will therefore increase the final size of the program) OFF

You can also customize the search root of JeMalloc/Libevent2/MbedTLS/OpenSSLx/PCRE with the following parameters.

-DOpenSSLx_ROOT=/xxxxxx/xxx/xxx for openssl root

-DLibevent2_ROOT=xxxxxx for libevent root

and so on

Run

pegas -c config.json -t 4

  • -c specifies the configuration file, by default it will try $XDG_CONFIG_HOME/.pegasrc or $XDG_CONFIG_HOME/pegas/config in order
  • -t specifies the number of worker threads, default is 4
  • -a specifies the ACL file if pegas is build with ACL feature

Configuration

see man page or wiki

Interaction

The "control_port" or "control_file" field of the configuration file can be used to open a TCP port or a unix socket to interact with the program. Use netcat / socat to interact with the relevant port or file.

  • GET SERVERS, which will return information about the server
  • SET SERVER $idx, which sets the current server

In linux socat demo

Also, the system tray is supported, see below

System Tray

Default compile binary without GUI, take parameter -DWITH_APPLET=ON to enable system tray.

cmake -DCMAKE_BUILD_TYPE=Release -DWITH_APPLET=ON . && make

Linux

To show the icon, put logo/icon.svg to where pegas sit.

OSX

On OSX, the binary will be packaged into an app bundle by default, just copy the packaged build/PegasApp.app to the application directly.

⚠️Note: If you encounter a situation where you can't start or hit a crash, please make sure that

  1. the latest libevent is installed in your system (do it manually, libevent2.12 from homebew will cause this issue)
  2. if there is a configuration file, the app bundle will detect ~/.config/.pegasrc or ~/.config/pegas/config
