Step 6: Download and run the Installer

Download the installer from GitHub by running the following command:

curl -L https://github.com/atsign-foundation/noports/releases/latest/download/universal.sh -o universal.sh

To check if the installation downloaded correctly:

stat universal.sh

Make the script executable and run the script by running the command below:

chmod u+x universal.sh
./universal.sh

During installation, you’ll be prompted to enter the following items:

You may be asked to enter your password if your machine requires sudo privileges.

The install type

  • Enter device when prompted.

Your atSigns

  • Client atSign: e.g., @example01_np

  • Device atSign: e.g., @example02_np

Your device name

  • This should be the name of the machine you're currently installing on.

Step 7: Initiate atSign authorization request

Run the following command to make an authorization request:

Be sure to replace the following values:

@<REPLACE>_np with your device atSign,

<PASSCODE> with the passcode generated in Step 5,

@<REPLACE>_np_key with your device atSign,

<DEVICE_NAME> with the name of the machine you are on

~/.local/bin/at_activate enroll -a @<REPLACE>_np \
  -s <PASSCODE> \
  -p noports \
  -k ~/.atsign/keys/@<REPLACE>_np_key.atKeys \
  -d <DEVICE_NAME> \
  -n "sshnp:rw,sshrvd:rw"

Once you see this text, you're ready to continue to the next step.

Step 8: Approve the atSign authorization request

  1. Click on Requests and approve the pending request. The request will then move to the approved enrollments list.

  2. After a few seconds, the request will also show as approved on the machine you are connecting to.

Step 9: Switch back to your client atSign (@example01_np)

  1. Click on your atSign in the top right corner of the screen. This will open a list of atSigns that are currently signed into the app.

  2. Select your client atSign in order to switch to it.

Step 10: Create a Connection Profile

  1. If you aren't already on the Connections tab, click on Connections at the top of the Screen. Then click Add New, to create a new profile.

  2. Enter the following information into the profile then click Submit.

    1. Profile Name - The name that will be displayed in the profile list.

    2. Device atSign - Your device atSign (eg example02_np).

    3. Device Name - The name of your remote device.

    4. Relay - Select the relay sever closest to you for optimum speed.

    5. Local Port - The port you will use on your local machine.

    6. Local Host - The hostname or IP address to bind to on your local machine.

    7. Remote Host - The hostname or IP address of the machine you are connecting to.

    8. Remote Port - The port that will be used on the remote machine.

For reference, we've documented our most common use cases, including MCP, SSH, RDP, SFTP, Web Server, and SMB.

Step 11: Establish a connection

Click the Connect Icon ▶️ to establish a connection with your remote device. If the connection is successful, you will see green. If you see red, hover over the icon to see reason for failure.
