Bypass SSH Jump Server Multi-Hop Complexity

🧩 The Challenge

Accessing internal servers hidden behind a bastion host often requires manual double-ssh procedures or complex proxy configurations.

💡 The Fix

Use the ProxyJump directive in your client configuration to transparently tunnel your connection through the gateway in a single command.

ssh -J user@jump-host user@destination-server

⚙️ Why It Works

The -J flag instructs the local SSH client to connect to the jump host and then perform a TCP forwarding request to the target destination, effectively flattening the connection path.

🚀 Pro-Tip: Add ProxyJump jump-host to the Host destination-server block in your ~/.ssh/config file to automate this tunnel every time you connect.
