# Linux Device Installation (hidden)

## Step 1 : Activate the device atSign from your `client machine`

If you've already activated the device atSign skip to [step 2](#step-2-installing-on-the-device).

### (1.1) Download the activation software on the `client machine`

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

To check if the installation downloaded correctly:

```bash
stat universal.sh
```

### (1.2) Run the installer

Make the script executable and run the script.

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

### (1.3) Activate the device atSign from the `client 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.

```
C:\\Program\ Files\\NoPorts\\at_activate.exe otp -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 management keys will be saved in `~\.atsign\keys`.

## Step 2 : Installing on the `device`

### (2.1) Download the installer

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

To check if the installation downloaded correctly:

```bash
stat universal.sh
```

### (2.2) Run the installer

Make the script executable and run the script.

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

## Step 3: Authorizing the device atSign

### (3.1) Generate a passcode from your `client machine`

### (3.2) Make an authorization request from your `device machine`

<pre class="language-bash"><code class="lang-bash">~/.local/bin/at_activate enroll -a @&#x3C;REPLACE>_device \
<strong>  -s &#x3C;PASSCODE> \
</strong><strong>  -p noports \
</strong><strong>  -k ~/.atsign/keys/@&#x3C;REPLACE>_device_key.atKeys \
</strong><strong>  -d &#x3C;DEVICE_NAME> \
</strong><strong>  -n "sshnp:rw,sshrvd:rw"
</strong></code></pre>

#### 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
```

### (3.3) Approve the authorization request from your `client machine`

Run the following command

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