What is the ProxyJump directive?

ProxyJump specifies one or more intermediate bastion or jump hosts to connect through before reaching the destination host. It eliminates the need for manual ssh -W commands.

Where should the generated SSH config be placed?

Save the file to ~/.ssh/config on Linux and macOS, or %USERPROFILE%\.ssh\config on Windows, ensuring file permissions are set to chmod 600 ~/.ssh/config.

Frequently Asked Questions

How does SSH connection multiplexing work?

Using ControlMaster auto and ControlPersist 10m, SSH reuses an existing background master connection for subsequent connections to the same host, drastically speeding up Git operations and new shell tabs without repeating authentication.

Are my hostnames or private keys safe?

Yes. The entire generator executes in JavaScript on your computer. QuickCoderHub makes zero server calls, ensuring private hostnames and internal IP addresses remain strictly confidential.
