SSH & Remote Administration

Stop jumping through middleman servers like it’s the nineties

🧩 The Challenge

Dealing with a jump box to reach an isolated database server is a daily grind that usually ends with me manually proxying ports or just getting annoyed at the connection chain. Nobody wants to deal with multi-stage authentication while they’re just trying to debug a live issue.

💡 The Fix

Use ProxyJump in your ssh config to have the client handle the heavy lifting for you automatically. It treats the middleman as a transparent tunnel and keeps your local sanity intact.

Host db-prod
HostName 10.0.5.20
ProxyJump user@bastion-host
User dbadmin

⚙️ Why It Works

This approach instructs your local SSH client to establish a connection to the bastion first and then tunnel the traffic directly to the target machine without you typing redundant passwords. It creates a seamless bridge that makes the remote server feel like it’s right on your subnet.

🚀 Pro-Tip: Add your SSH key to the local agent, and you won’t even have to re-enter a passphrase for the jump host.
