explains use cases and examples of SSH tunnels - A visual guide to SSH tunnels / HN

• Circumventing Deep Packet Inspection with Socat and rot13 / HN
  • Socat address chains

# ssh

ssh -N -L [local_port]:127.0.0.1:[remote_port] 100.69.234.21

# Port forwarding ⮺

# autossh

see Automatiser tunnel SSH

# ssh-config
Host bastion
    ServerAliveInterval 30
    ServerAliveCountMax 3
