Getting Started with AutoProxy: Installation, Configuration, and TipsAutoProxy is a tool designed to automate the management of proxy servers for routing web traffic. Whether you’re using proxies for privacy, testing, geo-routing, or performance, AutoProxy aims to simplify setup, handle failover, and make configuration reproducible. This guide covers installation, configuration, troubleshooting, and practical tips for getting the most from AutoProxy.
What AutoProxy does (brief overview)
AutoProxy automates the selection and management of proxy endpoints. Typical features include:
- Automatic failover between proxy nodes
- Health checks and latency-based selection
- Dynamic rules for routing traffic by domain, country, or IP
- Authentication management (basic, token, or per-proxy credentials)
- Logging and metrics for usage and performance
Installation
Prerequisites
Before installing AutoProxy, ensure you have:
- A system with a supported OS (Linux distributions are most commonly supported; check your distribution’s compatibility if using BSD/macOS/Windows).
- A recent version of Python (if AutoProxy is a Python-based tool), Node.js (if JS-based), or the appropriate runtime.
- Administrative or sudo privileges to modify system network settings or install services.
- Access to proxy endpoint credentials (if using authenticated proxies).
Installation methods
Below are common installation approaches. Choose the one matching your environment.
-
Install from package manager (preferred for stability)
- On Debian/Ubuntu:
sudo apt update sudo apt install autoproxy - On Fedora/RHEL (if available):
sudo dnf install autoproxy
- On Debian/Ubuntu:
-
Install via pip (Python-based distribution)
python3 -m pip install autoproxy -
Install via npm (Node-based distribution)
npm install -g autoproxy -
Install from source (latest features)
git clone https://example.com/autoproxy.git cd autoproxy ./install.sh -
Docker (recommended for isolation)
docker pull autoproxy/autoproxy:latest docker run -d --name autoproxy -p 3128:3128 -v /path/to/config:/etc/autoproxy autoproxy/autoproxy:latest
Configuration
AutoProxy typically uses a configuration file (YAML, JSON, or TOML). Below is a representative example in YAML to illustrate common settings.
# /etc/autoproxy/config.yaml listen: 0.0.0.0:3128 proxies: - name: proxy-eu address: proxy-eu.example.com:8080 type: http auth: user: user_eu pass: secret_eu health_check: /status weight: 1 - name: proxy-us address: proxy-us.example.com:8080 type: http auth: token: abcdef123456 health_check: /ping weight: 2 routing: default: direct rules: - match: "*.example.com" use: proxy-eu - match_country: US use: proxy-us - match_ip: "192.0.2.0/24" use: proxy-us health: interval: 30s timeout: 5s retries: 2 logging: level: info file: /var/log/autoproxy.log Key configuration concepts:
- listen — the interface and port AutoProxy exposes locally.
- proxies — list of upstream proxy endpoints and credentials.
- routing — domain/IP/country rules that map requests to proxies or direct connection.
- health — how frequently to check upstreams and what counts as failure.
- logging/metrics — set verbosity and log destination.
Authentication and Secrets Handling
Never store plaintext credentials in files accessible to other users. Use one of these approaches:
- Environment variables (set in systemd service file or Docker run)
- A secrets manager (HashiCorp Vault, AWS Secrets Manager)
- OS keyring services (gnome-keyring, macOS keychain)
- File permissions (config owned by root and mode 600)
Example systemd service snippet using environment file:
[Service] EnvironmentFile=/etc/autoproxy/env ExecStart=/usr/bin/autoproxy -c /etc/autoproxy/config.yaml /etc/autoproxy/env:
PROXY_US_TOKEN=abcdef123456 Permissions:
sudo chown root:root /etc/autoproxy/env sudo chmod 600 /etc/autoproxy/env Running AutoProxy as a Service
To run AutoProxy reliably on a server, use systemd (Linux). Example unit file:
[Unit] Description=AutoProxy Service After=network.target [Service] User=autoproxy Group=autoproxy ExecStart=/usr/bin/autoproxy -c /etc/autoproxy/config.yaml Restart=on-failure EnvironmentFile=/etc/autoproxy/env [Install] WantedBy=multi-user.target Enable and start:
sudo systemctl daemon-reload sudo systemctl enable autoproxy sudo systemctl start autoproxy sudo systemctl status autoproxy Verification and Troubleshooting
- Check logs:
- tail -f /var/log/autoproxy.log
- Confirm listening port:
- ss -ltnp | grep 3128
- Test routing:
- curl –proxy http://localhost:3128 https://ipinfo.io/json
- Use domain matches to verify rule-based behavior.
- Health check failures:
- Increase timeout/retries if upstreams are intermittently slow.
- Verify DNS resolution for upstream addresses.
- Authentication errors:
- Confirm credentials and token formatting.
- Check that credentials are being loaded (logs usually show masked secrets).
Security Best Practices
- Run AutoProxy under a dedicated unprivileged user.
- Limit network exposure: bind to localhost if only local apps use it; use firewall rules otherwise.
- Use TLS when available between AutoProxy and upstreams (CONNECT over TLS or HTTPS proxies).
- Rotate credentials and tokens regularly.
- Monitor logs for unusual activity or sudden traffic spikes.
Performance Tuning
- Connection pooling: increase pool size when serving many clients.
- Health check frequency: less frequent checks reduce overhead; more frequent checks improve responsiveness to failures.
- Cache DNS lookups if upstream IPs are stable.
- Set appropriate timeouts to avoid hanging client connections.
Use Cases & Examples
- Privacy: route sensitive requests through a chain of proxies in different jurisdictions.
- Geo-testing: force requests through region-specific proxies to validate geofenced content.
- Scaling: distribute outgoing requests across multiple proxies to avoid per-IP rate limits.
- Development: emulate client requests from different locations without changing machine network config.
Tips & Practical Advice
- Start simple: configure a single upstream and a basic rule set, then expand.
- Version control your configuration (but never commit secrets).
- Use monitoring/alerting for upstream failures and latency regressions.
- Test configuration changes in a staging environment before production rollout.
- Document which proxies are used for which purposes to keep team alignment.
Example: Minimal config to get started
listen: 127.0.0.1:3128 proxies: - name: proxy-default address: proxy.example.com:8080 type: http routing: default: proxy-default logging: level: info Start AutoProxy, point your browser or system proxy to 127.0.0.1:3128, and verify with an IP-check service.
