SSH USING IOS
To use SSH on your mobile device you need to download a client. There are several good quality clients available, such as Termius, Prompt 2, and Cathode.
For this tutorial we will use Termius, because it is a popular cross-platform SSH client. The process will be similar for other clients.
Download Termius from iTunes, if you haven’t installed it yet. Click to open the app.
A prompt asking you to allow notifications will pop up. You should click ‘Allow’ (recommended). Now follow the instruction on the screen:
Start by adding a new host. Tap New Host and a new window will pop up.
Enter an alias, such as ‘Tinker Board’. Then enter the IP address under hostname. Complete the username and password fields and hit ‘save’ in the top right corner.
If you do not know the IP address, type hostname –I in the command line on the Tinker Board. See here for more ways to find your IP address. The default login for debain is linaro with the password linaro.
When you have saved the new host, you will be sent back to the ‘Hosts’ screen. There you will find the new entry. Make sure your mobile device has wireless connectivity turned on, and is connected to the same network as your Tinker Board.
Tap the new entry once. When the connection works, you will see a security warning. Don’t worry, everything is fine! Click ‘Continue’. You will only see this warning the first time Termius connects to a linaro that it hasn’t seen before.
You should now have the Tinker Board prompt, which will be identical to the one found on the Tinker Board itself.
linaro@linaro-alip ~ $
You can type exit to close the terminal window.
If a red exclamation mark appears, this indicates that something has gone wrong. Tap the exclamation mark to see the error description. ‘Connection establishment time out’ indicates that you have probably entered an incorrect IP address. If the IP address is correct, wireless connectivity on your mobile device might be turned off; the Tinker Board might be turned off; or the Tinker Board and your mobile device might be connected to different networks.
A connection might be unsuccessful for various reasons. It is likely that your device or Tinker Board is not connected properly; SSH is disabled; there is a typo in your code; or the IP address or credentials have changed. In the latter cases, you will need to update the host.
To do so, go to the ‘Hosts’ screen, swipe left on the host you need to edit, and new functions will appear. Tap edit. A new screen titled ‘Edit Host’ will pop up.
