Linux to macOS

How to install NoPorts when connecting from Linux to macOS

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.

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

Step 2: Activate your client atSign

If you've already activated your client atSign on another device, this step will not work. Instead, follow this guide: Reuse your client atSign on another machine

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

Replace @<REPLACE>_client with your client atSign.

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

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

Run the same command, but for your device atSign.

Replace @<REPLACE>_device with your device atSign.

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

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.

Replace @<REPLACE>_device with your device atSign.

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

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.

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

Step 6: Initiate atSign authorization request

Run the following command to make an authorization request.

Be sure to replace the following values:

@<REPLACE>_device with your device atSign,

<PASSCODE> with the passcode generated in Step 4,

@<REPLACE>_device_key with your device atSign,

<DEVICE_NAME> with a unique name for the machine you are on

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

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

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:

Be sure to replace the following values:

@<REPLACE>_device with your device atSign,

@<REPLACE_NAME> with the unique device name from Step 6.

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

Connecting more machines to your device atSign

To connect more machines to your device atSign, repeat Steps 4 through 7.
