 The add-on uses host networking, so a resource can also point at any address on your network, such as a camera at `192.168.1.40`. Pick this site as the target and enter that address and port.
 
+## SSH server (optional)
+
+Turn on **SSH server** and list at least one key under **SSH public keys** (the line from your `id_ed25519.pub`, for example). Bamboo then runs an SSH server on `127.0.0.1:2222` inside the add-on. In Hammerhead, add a TCP port whose target is this site, host `127.0.0.1`, port `2222`, and connect with `ssh -p <port> anyname@<your edge address>`. The user name you give is ignored.

+This is a shell **inside the add-on's container**, as root: you can look around the add-on's own files and `/data`, and reach your network from it, but it is not the Home Assistant operating system or its terminal. Only the listed keys can sign in, with no passwords, and there is no port forwarding or SFTP. The server's host key is kept in `/data`, so it stays the same across restarts, and its fingerprint is in the add-on's log. Changes to the key list apply when the add-on is restarted.

 ## Suggest services (optional)
 
 Turn on **Suggest services** and Bamboo reports the services listening on Home Assistant's machine to Hammerhead, so you can pick one as a target instead of typing its address. Fill in **Scan subnets** (for example `192.168.1.0/24`) and it also looks for services on those networks, trying the ports in **Scan ports** or a short list of common ones. It is gentle, with a rate limit (**Scan speed**, 50 connection attempts per second by default) and a sweep every 15 minutes, and only private networks are accepted. Nothing is exposed until you pick a target. Only scan networks you are allowed to scan.
