SSH

In this guide, we demonstrate how to use SSH NoPorts to SSH to a remote machine.

Prerequisites

Before continuing, make sure that the following steps have been completed:

• NoPorts has been installed on both machines.

• Your NoPorts atSigns are activated, and the associated keys are saved locally.

If you haven’t completed these steps, follow the appropriate installation guide on the Installation Instructions page, then return here once finished.

Command Line

The command should look like:

sshnp -f @<client> -t @<device> -d <device name> -r @<relay> -i <your ssh key>

Example:

sshnp -f @alice_client -t @alice_device -d my_server -r @rv_am -i ~/.ssh/id_ed25519

Auto SSH key upload

If you don't have an ssh key uploaded on the remote machine, you can upload one by adding -s to the command:

sshnp -f @alice_client -t @alice_device -d my_server -r @rv_am -i ~/.ssh/id_ed25519 -s

Note: this feature can be disabled in sshnpd. If you get an error when using -s, it is likely that the administrator disabled this feature for security reasons.
