SSH is a way to connect to and control your OT-2 over the command line. It is required for some troubleshooting and advanced tasks.
SSH requires some first-time setup. Before following these instructions, make sure you've completed the setup guide:
Once that's done, you're ready to connect.
1. Find your OT-2's IP address
In the Opentrons App, find the OT-2 that you want to connect to. Note its Wired IP or Wireless IP.
- If you use the Wired IP, the SSH connection will be made over USB.
- If you use the Wireless IP, the SSH connection will be made over Wi-Fi.
We recommend connecting over USB when possible, because the connection will be more reliable.
These IP addresses will change periodically, especially after the OT-2 is restarted or reconnected. You should double-check the IP address each time you want to make an SSH connection.
Open a PowerShell window if you're on Windows 10, or a Terminal window if you're on Linux or macOS.
Enter the following command. Replace
ROBOT_IP with the IP address you found above.
ssh -i ot2_ssh_key root@ROBOT_IP
You may see a short warning saying "Permanently added [IP address] to the list of known hosts." You can safely ignore it.
3. After connecting
If the connection worked, you'll be greeted by the Opentrons logo. ✨
Try running some commands on your OT-2. For example, enter the command:
