Setting Up SSH Tunnels to IDNT Compute Instances (Linux and Mac OS X)

This guide explains how to create SSH tunnels to IDNT compute instances on Linux and Mac OS X systems.

SSH Tunneling

SSH tunnels provide secure connections to services running on remote compute instances by forwarding local ports through encrypted SSH connections.

Creating Tunnels

Local Port Forwarding

`ash ssh -L local_port:destination_host:destination_port user@gateway ``n

Dynamic Port Forwarding (SOCKS Proxy)

`ash ssh -D local_port user@gateway ``n

Common Use Cases

• Accessing web interfaces securely
• Database connections
• Development server access
• Bypassing network restrictions

Security Considerations

• Use strong authentication
• Limit tunnel lifetime
• Monitor active connections
• Close unused tunnels
