#### 7.1.2 Setting up Emacs ¶

Now we need to create the tunnel between the local machine and the remote machine.

    ssh -L4005:localhost:4005 username@remote.example.com

That ssh invocation creates an ssh tunnel between the port 4005 on our local machine and the port 4005 on the remote machine4.

Finally we can start SLIME:

    M-x slime-connect RET RET

The `RET RET` sequence just means that we want to use the default host (`localhost`) and the default port (`4005`). Even though we’re connecting to a remote machine the ssh tunnel fools Emacs into thinking it’s actually `localhost`.

#### Footnotes

##### (4)

By default swank listens for incoming connections on port 4005, had we passed a `:port` parameter to `swank:create-server` we’d be using that port number instead
