pegasocks 
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).

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
🍃 is light enough that there are no QT or boost or other third-party binary dependencies.🚀 Performance-first, with multiple worker threads by default, so theoretically higher throughput to be benchmarked)🚥 This is a learn by doing project, feel free to review the code, provide optimization ideas and C programming related guidance.❌ 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
-cspecifies the configuration file, by default it will try$XDG_CONFIG_HOME/.pegasrcor$XDG_CONFIG_HOME/pegas/configin order-tspecifies the number of worker threads, default is 4-aspecifies the ACL file if pegas is build with ACL feature
Configuration
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 serverSET 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.
- the latest libevent is installed in your system (do it manually, libevent2.12 from homebew will cause this issue)
- if there is a configuration file, the app bundle will detect
~/.config/.pegasrcor~/.config/pegas/config
