SSH2SOCKS5 Proxy

A lightweight SOCKS5 proxy that tunnels traffic through SSH connections. Available as both a standalone Go application and an Android app.

Features

• SOCKS5 proxy server that works over SSH tunnels
• SSH authentication using password or private key
• Android app with persistent connection management
• Automatic reconnection on connection loss

Requirements

• Nix package manager
• SSH key access to your server
• NekoBox app (for system-wide VPN on Android)

SSH Setup

1. Generate SSH key (if you don't have one):

ssh-keygen -t rsa -b 4096 -f ~/.ssh/google-france-key

2. Copy public key to your server:

ssh-copy-id -i ~/.ssh/google-france-key.pub username@your_server

Quick Start

1. Install Nix and direnv:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

2. Set up the environment:

cd ssh2socks5
direnv allow

Or use:

nix develop

3. Build:

For Android app:

make build-android

For standalone proxy:

make build-go

4. Run the proxy:

make run

• or

nix run github:back2nix/ssh2socks5#ssh2socks5 -- -lport=1081 -host=35.193.63.104 -user=bg -key=/home/bg/Documents/code/backup/.ssh/google-france-key

• or

nix run .#ssh2socks5 -- -lport=1081 -host=35.193.63.104 -user=bg -key=/home/bg/Documents/code/backup/.ssh/google-france-key

Решение - увеличить лимиты в SSH:

sudo vim /etc/ssh/sshd_config

Найдите и измените/добавьте:

ClientAliveInterval 60
ClientAliveCountMax 2
TCPKeepAlive yes

# Для большего количества подключений
MaxStartups 100:30:200
MaxSessions 500

# Увеличиваем время на аутентификацию, чтобы меньше банило
LoginGraceTime 300
MaxAuthTries 300

# Отключаем DNS lookup для ускорения подключений
UseDNS no

Перезапустите SSH:

sudo systemctl restart ssh

Host hetzener_usa_d1
    HostName 5.161.216.208
    User root
    IdentityFile /home/bg/.ssh/id_rsa
    ControlMaster auto
    ControlPath ~/.ssh/control-%r@%h:%p
    ControlPersist 600

Usage

Desktop

Configure your applications to use the SOCKS5 proxy at 127.0.0.1:1081 (default port).

Android

1. Install the SSH2SOCKS5 APK
2. Enter your SSH server details and private key
3. Start the proxy

Note: The app itself doesn't create a system-wide VPN. To route all device traffic through the proxy:

1. Install NekoBox from F-Droid or Google Play
2. Create a new SOCKS5 connection in NekoBox
3. Configure it to connect to 127.0.0.1:1081
4. Enable the VPN in NekoBox to route all device traffic through the proxy
