# KKClaw Server Optimized OpenClaw client for Ubuntu/Raspbian as remote server. ## Overview KKClaw Server is a headless version of KKClaw designed for Ubuntu and Raspbian servers. It runs without GUI, perfect for Raspberry Pi or cloud instances. ## Features ### 1. Heartbeat Mechanism - Configurable heartbeat interval (default: 30s) - Status reporting to gateway - Memory and uptime monitoring - Automatic connection monitoring ### 2. Auto Reconnect - Exponential backoff reconnection - Max retry limit with configurable attempts - Persistent connection monitoring - Graceful degradation ### 3. Auto Recovery - Automatic session recovery - Queue restoration after disconnect - Model auto-rollback on failure - Max restart attempts ### 4. Queue Management - Message queuing when disconnected - Automatic retry with backoff - Queue size limits - FIFO processing ### 5. Model Switching - Hot model switching without restart - Fallback model support - Auto-rollback on failure - Timeout protection ## Quick Start ```bash # Initialize config kkclaw-server init # Start server kkclaw-server start # Check status kkclaw-server status # Switch model kkclaw-server model minimax-portal/MiniMax-M2.5 ``` ## Configuration Edit `~/.kkclaw/config.json`: ```json { "gateway": { "url": "http://your-gateway:18789", "apiKey": "your-api-key" }, "heartbeat": { "enabled": true, "interval": 30000 }, "reconnect": { "enabled": true, "maxRetries": 10, "baseDelay": 1000 }, "recovery": { "enabled": true, "maxRestarts": 5 }, "queue": { "maxSize": 100, "maxRetries": 3 }, "models": { "default": "claude-opus-4-6", "fallback": "minimax-portal/MiniMax-M2.5" } } ``` ## Systemd Service (Raspbian/Ubuntu) Create `/etc/systemd/system/kkclaw.service`: ```ini [Unit] Description=KKClaw Server After=network.target [Service] Type=simple User=pi WorkingDirectory=/home/pi/kkclaw ExecStart=/usr/bin/node /home/pi/kkclaw/main.js start Restart=always RestartSec=10 [Install] WantedBy=multi-user.target ``` Then: ```bash sudo systemctl daemon-reload sudo systemctl enable kkclaw sudo systemctl start kkclaw ``` ## Features Detail ### Heartbeat - Sends periodic heartbeats to gateway - Reports: status, model, queue length, memory, uptime - Detects connection issues early ### Auto Reconnect - Exponential backoff: 1s, 2s, 4s, 8s... up to 60s - Max 10 retries by default - Manual reconnect available ### Auto Recovery - Clears failed session state - Restores queued messages - Auto-rollback to previous model on failure ### Queue Management - Queues messages when disconnected - Automatic retry with exponential backoff - Removes failed messages after max retries ### Model Switching - Hot switch without restart - Timeout: 30s default - Auto fallback to default model on failure ## CLI Commands | Command | Description | |---------|-------------| | `init` | Create default config | | `start` | Start server | | `status` | Show current status | | `connect` | Manual connect | | `model <name>` | Switch model | | `queue` | Show queue info | ## Author Glitch (OpenClaw agent)
