Overview
--------
# Overview
This project is a very simple gemini server which only serves static files,
nothing else. It is meant to be generic so other people can use it.
Setup
=====
# Build/Test/Lint Commands
This is a modern Rust project with the default rust setup.
## Core Commands
- `cargo build` - Build the project
- `cargo build --release` - Build optimized release version
- `cargo run` - Run the server with default config
- `cargo test` - Run all unit tests
- `cargo test <test_name>` - Run a specific test
- `cargo test <module>::tests` - Run tests in a specific module
- `cargo clippy` - Run linter checks for code quality
- `cargo clippy --fix` - Automatically fix clippy suggestions
- `cargo clippy --bin <name>` - Check specific binary
- `cargo fmt` - Format code according to Rust standards
- `cargo check` - Quick compile check without building
Security
========
## Common Test Patterns
- `cargo test config::tests` - Run config module tests
- `cargo test request::tests` - Run request handling tests
- `cargo test -- --nocapture` - Show println output in tests
In this project cyber security is very important because we are implementing
a server which reads arbitrary data from other computers and we need to make
sure that bad actors can't break it and read random things from outside
the directory, or even worse write things.
# Code Style Guidelines
Testing
=======
We have UnitTests which should be kept up to date before committing any new code.
## Imports
- Group imports: std libs first, then external crates, then local modules
- Use `use crate::module::function` for internal imports
- Prefer specific imports over `use std::prelude::*`
- Keep imports at module level, not inside functions
Fix every compiler warning before committing.
## Code Structure
- Use `#[tokio::main]` for async main function
- Keep functions small and focused (single responsibility)
- Use `const` for configuration values that don't change
- Error handling with `Result<T, E>` and `?` operator
- Use `tracing` for logging, not `println!` in production code
### Certificate Management
## Naming Conventions
- `PascalCase` for types, structs, enums
- `snake_case` for functions, variables, modules
- `SCREAMING_SNAKE_CASE` for constants
- Use descriptive names that indicate purpose
Development
- Generate self-signed certificates for local testing
- Store in `certs/` directory (gitignored)
## Error Handling
- Use `io::Result<()>` for I/O operations
- Convert errors to appropriate types with `map_err` when needed
- Use `unwrap()` only in tests and main() for unrecoverable errors
- Use `expect()` with meaningful messages for debugging
- Return early with `Err()` for validation failures
## Security Requirements
- **Critical**: Always validate file paths with `path_security::validate_path`
- Never construct paths from user input without validation
- Use timeouts for network operations (`tokio::time::timeout`)
- Limit request sizes (see `MAX_REQUEST_SIZE` constant)
- Validate TLS certificates properly
- Never expose directory listings
## Testing Guidelines
- Use `tempfile::TempDir` for temporary directories in tests
- Test both success and error paths
- Use `#[cfg(test)]` for test modules
- Create temporary test files in `tmp/` directory
- Test security boundaries (path traversal, invalid inputs)
- Use `assert_eq!` and `assert!` for validations
## Lint Checking
- `cargo clippy` - Run linter checks for code quality
- `cargo clippy --fix` - Automatically fix clippy suggestions
- `cargo clippy --bin <name>` - Check specific binary
- `cargo fmt` - Format code to match Rust standards
- **Run clippy before every commit** - Address all warnings before pushing code
- Current clippy warnings (2025-01-15):
- src/server.rs:16-17 - Unnecessary borrows on file_path
- src/logging.rs:31 - Match could be simplified to let statement
## Testing
- Run `cargo test` before every commit to prevent regressions
- Pre-commit hook automatically runs full test suite
- Rate limiting integration test uses separate port for isolation
- All tests must pass before commits are allowed
- Test suite includes: unit tests, config validation, rate limiting under load
## Async Patterns
- Use `.await` on async calls
- Prefer `tokio::fs` over `std::fs` in async contexts
- Handle timeouts for network operations
- Use `Arc<Clone>` for shared data across tasks
## Gemini Protocol Specific
- Response format: "STATUS META\r\n"
- Status 20: Success (follow with MIME type)
- Status 41: Server unavailable (timeout, overload)
- Status 51: Not found (resource doesn't exist)
- Status 59: Bad request (malformed URL, protocol violation)
- Default MIME: "text/gemini" for .gmi files
- Default file: "index.gmi" for directory requests
## Error Handling
- **Concurrent request limit exceeded**: Return status 41 "Server unavailable"
- **Timeout**: Return status 41 "Server unavailable" (not 59)
- **Request too large**: Return status 59 "Bad request"
- **Empty request**: Return status 59 "Bad request"
- **Invalid URL format**: Return status 59 "Bad request"
- **Hostname mismatch**: Return status 59 "Bad request"
- **Path resolution failure**: Return status 51 "Not found" (including security violations)
- **File not found**: Return status 51 "Not found"
- Reject requests > 1024 bytes (per Gemini spec)
- Reject requests without proper `\r\n` termination
- Use `tokio::time::timeout()` for request timeout handling
- Configurable concurrent request limit: `max_concurrent_requests` (default: 1000)
## Configuration
- TOML config files with `serde::Deserialize`
- CLI args override config file values
- Required fields: root, cert, key, host
- Optional: port, log_level, max_concurrent_requests
# Development Notes
- Generate self-signed certificates for local testing in `tmp/` directory
- Use CN=localhost for development
- Fix every compiler warning before committing any code
- Create temporary files in the tmp/ directory for your tests like .gem files
or images, etc., so they are gitignored
- Use `path-security` crate for path validation
- Default port: 1965 (standard Gemini port)
- Default host: 0.0.0.0 for listening
- Log level defaults to "info"
Production
- Use Let's Encrypt or CA-signed certificates
- Store certificates outside repository
- Set appropriate file permissions (600 for keys, 644 for certs)
- Implement certificate renewal monitoring
- Never include private keys in documentation or commits
Deployment Security
- Certificate files should be owned by service user
- Use systemd service file with proper User/Group directives
- Consider using systemd's `LoadCredential` for certificate paths
## Environment Setup
- Install clippy: `rustup component add clippy`
- Ensure `~/.cargo/bin` is in PATH (add `source "$HOME/.cargo/env"` to `~/.bashrc`)
- Verify setup: `cargo clippy --version`

# Pollux Gemini Server - Logging Implementation Complete
## Summary
Successfully implemented Apache/Nginx-style logging for the Pollux Gemini server with the following features:
### ✅ Implemented Features
1. **Plain Text Log Format** - As requested, compatible with standard log analysis tools
2. **Consistent Field Order** - `<IP> "<URL>" <status> ["<message>"]` for both success and error logs
3. **stdout/stderr Output** - Ready for systemd integration
4. **Client IP Extraction** - Extracts IP from TLS connections
5. **Gemini Status Codes** - Logs actual Gemini protocol status codes (20, 51, 59, etc.)
6. **Error Messages** - Detailed error descriptions for troubleshooting
### 📋 Log Format
**Access Logs (stdout):**
```
127.0.0.1 "gemini://jeena.net/" 20
192.168.1.100 "gemini://jeena.net/posts/vibe-coding.gmi" 20
```
**Error Logs (stderr):**
```
192.168.1.100 "gemini://jeena.net/posts/nonexistent.gmi" 51 "File not found"
192.168.1.100 "gemini://jeena.net/../etc/passwd" 59 "Path traversal attempt"
```
### 🖥️ systemd Integration
When run as a systemd service:
- **Access logs**: `journalctl -u pollux`
- **Error logs**: `journalctl -u pollux -p err`
- **Timestamps**: Automatically added by systemd
- **Rotation**: Handled by journald configuration
- **Filtering**: Standard journalctl filtering works
### 📁 Files Modified
- `src/logging.rs` - New logging module with RequestLogger
- `src/server.rs` - Integrated logging into connection handling
- `src/main.rs` - Added log level configuration
- `src/config.rs` - Added log_level config option
- `Cargo.toml` - Added tracing dependencies
### ⚙️ Configuration
```toml
log_level = "info" # debug, info, warn, error
```
### 🧪 Gemini Protocol Considerations
- **No User-Agent**: Gemini protocol doesn't have HTTP-style User-Agent headers
- **No Referer**: Not part of Gemini specification (privacy-focused design)
- **Client IP**: Extracted from TLS connection (best available)
- **Status Codes**: Uses actual Gemini protocol codes
### ✅ Testing
- All 14 tests pass
- Server compiles cleanly (no warnings)
- Logging verified to produce correct format
- Compatible with systemd journalctl
### 🚀 Ready for Production
The server now has production-grade logging that:
- Works with existing log analysis tools (grep, awk, logrotate)
- Integrates seamlessly with systemd
- Provides essential debugging information
- Follows Apache/Nginx conventions
- Supports the Gemini protocol appropriately
### Usage Examples
```bash
# View live logs
journalctl -u pollux -f
# Filter access logs
journalctl -u pollux | grep -v "ERROR"
# Filter error logs
journalctl -u pollux -p err
# Time range filtering
journalctl -u pollux --since "1 hour ago"
```
Implementation complete and ready for deployment!

port = 1965
log_level = "info"
max_concurrent_requests = 1000
```
## Certificate Setup
### Development
Generate self-signed certificates for local testing:
## Development Setup
### Quick Start with Self-Signed Certs
```bash
mkdir -p certs
openssl req -x509 -newkey rsa:2048 -keyout certs/key.pem -out certs/cert.pem -days 365 -nodes -subj "/CN=localhost"
mkdir -p tmp
openssl req -x509 -newkey rsa:2048 \
-keyout tmp/key.pem \
-out tmp/cert.pem \
-days 365 \
-nodes \
-subj "/CN=localhost"
```
Update `config.toml`:
```toml
cert = "certs/cert.pem"
key = "certs/key.pem"
cert = "tmp/cert.pem"
key = "tmp/key.pem"
```
### Production
Use Let's Encrypt for production:
```bash
sudo certbot certonly --standalone -d yourdomain.com
```
Then update config.toml paths to your certificate locations.
Run the server:
```bash
./pollux --config /path/to/config.toml
```
Or specify options directly (overrides config):
```bash
./pollux --root /path/to/static/files --cert cert.pem --key key.pem --host yourdomain.com --port 1965
```
Access with a Gemini client like Lagrange at `gemini://yourdomain.com/`.
### Development Notes
- These certificates are for local testing only
- Browsers will show security warnings with self-signed certs
- Certificates in the `dev/` directory are gitignored for security
## Options
- `--config`: Path to config file (default `/etc/pollux/config.toml`)
- `--root`: Directory to serve files from (required)
- `--cert`: Path to certificate file (required)
- `--key`: Path to private key file (required)
- `--host`: Hostname for validation (required)
- `--port`: Port to listen on (default 1965)
## Security
Uses path validation to prevent directory traversal. Validate hostnames for production use.
- `--config` (`-C`): Path to config file (default `/etc/pollux/config.toml`)
- `--test-processing-delay` (debug builds only): Add delay before processing requests (seconds) - for testing rate limiting
### Certificate Management
- Never commit certificate files to version control
- Use development certificates only for local testing
- Production certificates should be obtained via Let's Encrypt or your CA
## Testing
Run `cargo test` for unit tests. Fix warnings before commits.
Run `cargo test` for the full test suite, which includes integration tests that require Python 3.
**Note**: Integration tests use Python 3 for Gemini protocol validation. If Python 3 is not available, integration tests will be skipped automatically.

# Installing Pollux Gemini Server
This guide covers installing and configuring the Pollux Gemini server for production use.
## Prerequisites
- Linux system with systemd
- Rust toolchain (for building from source)
- Domain name with DNS configured
- Let's Encrypt account (for certificates)
## Quick Start
```bash
# 1. Build and install
cargo build --release
sudo cp target/release/pollux /usr/local/bin/
# 2. Get certificates
sudo certbot certonly --standalone -d example.com
# 3. Create directories and user
sudo useradd -r -s /bin/false pollux
sudo usermod -a -G ssl-cert pollux
sudo mkdir -p /etc/pollux /var/www/example.com
sudo chown -R pollux:pollux /var/www/example.com
# 4. Install config
sudo cp dist/config.toml /etc/pollux/
# 5. Add your Gemini content
sudo cp -r your-content/* /var/www/example.com/
# 6. Install and start service
sudo cp dist/pollux.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable pollux
sudo systemctl start pollux
# 7. Check status
sudo systemctl status pollux
sudo journalctl -u pollux -f
```
## Detailed Installation
### Building from Source
```bash
git clone https://github.com/yourusername/pollux.git
cd pollux
cargo build --release
sudo cp target/release/pollux /usr/local/bin/
```
### Certificate Setup
#### Certificate Setup
**For Production:** Obtain certificates from your preferred Certificate Authority and place them in `/etc/pollux/`. Ensure they are readable by the pollux user.
**For Development/Testing:** Generate self-signed certificates (see Quick Start section).
**Note:** Let's Encrypt certificates can be used but their installation and permission setup is beyond the scope of this documentation.
```bash
# Generate certificates
openssl req -x509 -newkey rsa:4096 \
-keyout /etc/pollux/key.pem \
-out /etc/pollux/cert.pem \
-days 365 -nodes \
-subj "/CN=example.com"
# Set permissions
sudo chown pollux:pollux /etc/pollux/*.pem
sudo chmod 644 /etc/pollux/cert.pem
sudo chmod 600 /etc/pollux/key.pem
```
### User and Directory Setup
```bash
# Create service user
sudo useradd -r -s /bin/false pollux
# Add to certificate group (varies by distro)
sudo usermod -a -G ssl-cert pollux # Ubuntu/Debian
# OR
sudo usermod -a -G certbot pollux # Some systems
# Create directories
sudo mkdir -p /etc/pollux /var/www/example.com
sudo chown -R pollux:pollux /var/www/example.com
```
### Configuration
Edit `/etc/pollux/config.toml`:
```toml
root = "/var/www/example.com"
cert = "/etc/pollux/cert.pem"
key = "/etc/pollux/key.pem"
bind_host = "0.0.0.0"
hostname = "example.com"
port = 1965
max_concurrent_requests = 1000
log_level = "info"
```
### Content Setup
```bash
# Copy your Gemini files
sudo cp -r gemini-content/* /var/www/example.com/
# Set permissions
sudo chown -R pollux:pollux /var/www/example.com
sudo find /var/www/example.com -type f -exec chmod 644 {} \;
sudo find /var/www/example.com -type d -exec chmod 755 {} \;
```
### Service Installation
```bash
# Install service file
sudo cp dist/pollux.service /etc/systemd/system/
# If your paths differ, edit the service file
sudo editor /etc/systemd/system/pollux.service
# Update ReadOnlyPaths to match your config
# Enable and start
sudo systemctl daemon-reload
sudo systemctl enable pollux
sudo systemctl start pollux
```
### Verification
```bash
# Check service status
sudo systemctl status pollux
# View logs
sudo journalctl -u pollux -f
# Test connection
openssl s_client -connect example.com:1965 -servername example.com <<< "gemini://example.com/\r\n" | head -1
```
## Troubleshooting
### Permission Issues
```bash
# Check certificate access
sudo -u pollux cat /etc/pollux/cert.pem
# Check content access
sudo -u pollux ls -la /var/www/example.com/
```
### Port Issues
```bash
# Check if port is in use
sudo netstat -tlnp | grep :1965
# Test binding
sudo -u pollux /usr/local/bin/pollux # Should show startup messages
```
### Certificate Issues
```bash
# Renew certificates
sudo certbot renew
# Reload service after cert renewal
sudo systemctl reload pollux
```
## Configuration Options
See `config.toml` for all available options. Key settings:
- `root`: Directory containing your .gmi files
- `cert`/`key`: TLS certificate paths
- `bind_host`: IP/interface to bind to
- `hostname`: Domain name for URI validation
- `port`: Listen port (1965 is standard)
- `max_concurrent_requests`: Connection limit
- `log_level`: Logging verbosity
## Certificate Management
The server uses standard systemd restart for certificate updates. Restart time is less than 1 second.
### Let's Encrypt Integration
For automatic certificate renewal with certbot:
```bash
# Create post-renewal hook
sudo tee /etc/letsencrypt/renewal-hooks/post/restart-pollux.sh > /dev/null << 'EOF'
#!/bin/bash
# Restart Pollux after Let's Encrypt certificate renewal
systemctl restart pollux
logger -t certbot-pollux-restart "Restarted pollux after certificate renewal"
EOF
# Make it executable
sudo chmod +x /etc/letsencrypt/renewal-hooks/post/restart-pollux.sh
# Test the hook
sudo /etc/letsencrypt/renewal-hooks/post/restart-pollux.sh
```
### Manual Certificate Update
```bash
# Restart server to load new certificates
sudo systemctl restart pollux
# Check restart in logs
sudo journalctl -u pollux -f
```
## Upgrading
```bash
# Stop service
sudo systemctl stop pollux
# Install new binary
sudo cp target/release/pollux /usr/local/bin/
# Start service
sudo systemctl start pollux
```
## Security Notes
- Certificates are read-only by the service user
- Content directory is read-only
- No temporary file access
- Systemd security hardening applied
- Private keys have restricted permissions
- URI validation prevents domain confusion attacks

# Pollux Gemini Server Configuration
#
# This is an example configuration file for the Pollux Gemini server.
# Copy this file to /etc/pollux/config.toml and customize the values below.
#
# The Gemini protocol is specified in RFC 1436: https://tools.ietf.org/rfc/rfc1436.txt
# Directory containing your Gemini files (.gmi, .txt, images, etc.)
# The server will serve files from this directory and its subdirectories.
# Default index file is 'index.gmi' for directory requests.
#
# IMPORTANT: The server needs READ access to this directory.
# Make sure the service user (gemini) can read all files here.
root = "/var/www/example.com"
# TLS certificate and private key files
# These files are required for TLS encryption (Gemini requires TLS).
#
# For Let's Encrypt certificates (recommended for production):
# cert = "/etc/letsencrypt/live/example.com/fullchain.pem"
# key = "/etc/letsencrypt/live/example.com/privkey.pem"
#
# To obtain Let's Encrypt certs:
# sudo certbot certonly --standalone -d example.com
#
# For development/testing, generate self-signed certs:
# openssl req -x509 -newkey rsa:4096 -keyout /etc/pollux/key.pem -out /etc/pollux/cert.pem -days 365 -nodes -subj "/CN=example.com"

key = "/etc/letsencrypt/live/example.com/privkey.pem"
# Server network configuration
#
# bind_host: IP address or interface to bind the server to
# - "0.0.0.0" = listen on all interfaces (default)
# - "127.0.0.1" = localhost only
# - "::" = IPv6 all interfaces
# - Specific IP = bind to that address only
bind_host = "0.0.0.0"
# hostname: Domain name for URI validation
# - Used to validate incoming gemini:// URIs
# - Clients must use: gemini://yourdomain.com
# - Server validates that requests match this hostname
hostname = "example.com"
# port: TCP port to listen on
# - Default Gemini port is 1965
# - Ports below 1024 require root privileges
# - Choose a different port if 1965 is in use
port = 1965
# Request limiting
#
# max_concurrent_requests: Maximum number of simultaneous connections
# - Prevents server overload and DoS attacks
# - Set to 0 to disable limiting (not recommended)
# - Typical values: 100-10000 depending on server capacity
max_concurrent_requests = 1000
# Logging configuration
#
# log_level: Controls how much information is logged
# - "error": Only errors that prevent normal operation
# - "warn": Errors plus warnings about unusual conditions
# - "info": General operational information (recommended)
# - "debug": Detailed debugging information
# - "trace": Very verbose debugging (use only for troubleshooting)
