tmux Session Resume: Never Lose Your Work Again

The Disconnection Problem

Network connections drop. Laptops close. VPN tunnels time out. When your SSH session dies, you lose your terminal state -- running processes, scroll-back buffer, carefully arranged panes. You reconnect and start over, reattaching manually to tmux, navigating back to where you were.

JumpTerm's session resume feature eliminates this friction. When you connect to a host, JumpTerm detects existing tmux sessions and reattaches automatically. Your pane layouts, running processes, and scroll-back history are all preserved exactly as you left them.

How to Use It

Enable tmux resume in your connection settings by editing a connection and going to the Session tab. Set a default session name (like "work" or "deploy") and enable auto-attach. The next time you connect, JumpTerm will find that session and attach without any prompts.

If you want more control, leave auto-attach off and JumpTerm will show you a list of available sessions each time you connect. Pick the one you want, or create a new one.

Cross-Device Workflow

Here is the real power of session resume: start a long-running task on your desktop at the office, close your laptop, commute home, and pick it up on your home machine. The tmux session is running on the server, so it does not matter which device you connect from. JumpTerm finds it and reattaches seamlessly.

This is especially useful for deployments, database migrations, and any task that takes longer than you expected. You are never tethered to a single device or network connection.
