How to install NoPorts when connecting from Linux to Linux

Step 1 to Step 4

These initial steps set up the machine initiating the connection.

On the machine you are connecting from

Step 1: 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

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

The install type

  • Enter client when prompted.

Your atSigns (Skip this step)

  • To skip this step, simply press the Enter/Return key twice. Your atSigns will be activated in the upcoming steps.

Step 2: Activate your client atSign (@example01_np)

This command activates your atSign and prompts you to enter an OTP. This is only done during the setup of a brand new atSign.

~/.local/bin/at_activate -a @<REPLACE>_np

Enter the one-time password (OTP) & Check your SPAM/PROMOTIONS folders

at_activate will pause and wait for the input of a one-time pin (OTP) sent to your email or phone number. Once activated, the master keys will save at ~/.atsign/keys.

Step 3: Activate your device atSign (@example02_np)

Run the same command, but for your device atSign.

~/.local/bin/at_activate -a @<REPLACE>_np

Enter the one-time password (OTP) & Check your SPAM/PROMOTIONS folders

at_activate will pause and wait for the input of a one-time pin (OTP) sent to your email or phone number. Once activated, the master keys will save at ~/.atsign/keys.

Step 4: Generate an atSign authorization passcode for your device atSign

Run the following command to generate a 6-character one-time passcode. You will use this passcode in Step 6.

~/.local/bin/at_activate otp -a @<REPLACE>_np

Step 5 and Step 6

After setting up the machine you're connecting from, you'll configure the machine you're connecting to.

On the machine you are connecting to

Step 5: 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 6: Initiate atSign authorization request

Run the following command to make an authorization request.

~/.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.

Submitting enrollment request 
Enrollment ID: ---------------------
Waiting for approval; will check every 10 seconds

Step 7 and Step 8

With both machines now configured, the final steps bring us back to the machine initiating the connection.

On the machine you are connecting from

Step 7: Approve the atSign authorization request

Run the following command:

~/.local/bin/at_activate approve -a @<REPLACE>_np --arx noports --drx <DEVICE_NAME>

Step 8: Use NoPorts!

That's it. You can start using NoPorts or explore some of the documented use cases, including MCP, SSH, RDP, SFTP, Web Server, and SMB.
