This guide covers advanced OpenSSH configuration for connecting to IDNT Compute instances via Cloud Shell on Linux systems.

Advanced SSH Configuration

SSH Config File

Create ~/.ssh/config with optimized settings:

`ash Host idnt-gateway HostName gateway.idnt.net User your-username IdentityFile ~/.ssh/id_rsa ServerAliveInterval 60 ServerAliveCountMax 3 Compression yes ``n

Performance Optimization

  • Compression: Enable for slow connections
  • Keep-Alive: Maintain persistent connections
  • Multiplexing: Reuse connections for multiple sessions
  • Cipher Selection: Optimize encryption algorithms

Security Enhancements

  • Key-only Authentication: Disable password auth
  • Host Key Verification: Enable strict checking
  • Agent Forwarding: Use with caution
  • Port Knocking: Additional security layer

Troubleshooting

  • Connection timeouts
  • Authentication failures
  • Network configuration issues
  • Performance problems
