# SSH
|
|
|
|
## Quick Start
|
|
|
|
In order to SSH into your device, you'll need a GitHub account with SSH keys. See this [GitHub article](https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh) for getting your account setup with SSH keys.
|
|
|
|
* Enable SSH in your device's settings
|
|
* Enter your GitHub username in the device's settings
|
|
* Connect to your device
|
|
* Username: `comma`
|
|
* Port: `22` or `8022`
|
|
|
|
Here's an example command for connecting to your device using its tethered connection:<br />
|
|
`ssh comma@192.168.43.1`
|
|
|
|
For doing development work on device, it's recommended to use [SSH agent forwarding](https://docs.github.com/en/developers/overview/using-ssh-agent-forwarding).
|
|
|
|
## Notes
|
|
|
|
The public keys are only fetched from your GitHub account once. In order to update your device's authorized keys, you'll need to re-enter your GitHub username.
|
|
|
|
The `id_rsa` key in this directory only works while your device is in the setup state with no software installed. After installation, that default key will be removed.
|
|
|
|
See the [community wiki](https://github.com/commaai/openpilot/wiki/SSH) for more detailed instructions and information.

# Connecting to ssh.comma.ai
|
|
SSH into your comma device from anywhere with `ssh.comma.ai`.
|
|
|
|
## Setup
|
|
|
|
With software version 0.6.1 or newer, enter your GitHub username on your device under Developer Settings. Your GitHub authorized public keys will become your authorized SSH keys for `ssh.comma.ai`. You can add any additional keys in `/system/comma/home/.ssh/authorized_keys.persist`.
|
|
|
|
Requires [comma SIM with comma prime](https://comma.ai/shop) activated with comma connect, available on iOS and Android. comma two and EON ship with a pre-inserted comma SIM.
|
|
|
|
## Recommended .ssh/config
|
|
|
|
With the below SSH configuration, you can type `ssh comma-{dongleid}` to connect to your device through `ssh.comma.ai`.<br />
|
|
For example: `ssh comma-ffffffffffffffff`
|
|
|
|
```
|
|
Host comma-*
|
|
Port 22
|
|
User comma
|
|
IdentityFile ~/.ssh/my_github_key
|
|
ProxyCommand ssh %h@ssh.comma.ai -W %h:%p
|
|
Host ssh.comma.ai
|
|
Hostname ssh.comma.ai
|
|
Port 22
|
|
IdentityFile ~/.ssh/my_github_key
|
|
```
|
|
|
|
## One-off connection
|
|
|
|
```
|
|
ssh -i ~/.ssh/my_github_key -o ProxyCommand="ssh -i ~/.ssh/my_github_key -W %h:%p -p %p %h@ssh.comma.ai" comma@ffffffffffffffff
|
|
```
|
|
(Replace `ffffffffffffffff` with your dongle_id)
|
|
|
|
## ssh.comma.ai host key fingerprint
|
|
|
|
```
|
|
Host key fingerprint is SHA256:X22GOmfjGb9J04IA2+egtdaJ7vW9Fbtmpz9/x8/W1X4
