Teleconsole is built on top of Gravitational Teleport which is a modern SSH server for remotely accessing clusters of Linux servers via SSH or HTTPS. It is an “instant” SSH server which is pre-configured to trust teleconsole.com SSH proxy. Make sure both user should have teleconsole app in the system.
- Simply type teleconsole in your terminal, it generates unique single-use SSH credentials and launches an SSH server on localhost.
- The server (https://teleconsole.com) creates a single-use disposable instance of Teleport SSH proxy, after getting the SSH credentials, which is trusted by the teleconsole SSH server running on your machine.
- Your local teleconsole SSH server creates an outbound SSH tunnel to the disposable Teleport proxy running on (https://teleconsole.com). The proxy now acts as a bridge connecting the outside world to your machine.
- When you type teleconsole join session-id, teleconsole requests the proxy for SSH keys for the session via HTTPS.

- The proxy forwards the connection through the tunnel created in your machine.
