n8n-nodes-customssh

This is an n8n community node for advanced SSH connections with configurable ciphers and network device support. It's designed specifically for connecting to network devices that may have non-standard SSH configurations.

Features

• Advanced SSH Configuration: Support for custom ciphers, key exchange algorithms, and SSH protocols
• Network Device Support: Optimized for Cisco, Juniper, Arista, and other network equipment
• Configurable Authentication: Multiple authentication methods including password and key-based
• Command Execution: Execute commands on remote devices with proper output handling
• AI Integration: Marked as usableAsTool: true for AI agent compatibility
• Robust Connection Management: Handles connection timeouts, retries, and device-specific requirements
