# Step 2: Download Stader node

### Step 2.1 Open your system ports

A good practice for security would be to close all the ports on your system and then open only the required ports. Below is the list of ports to be opened:

* Execution client: 30303 tcp/udp
* Lighthouse: 9001 tcp/udp
* Prysm: 13000 tcp and 12000 udp

###

### Step 2.2 Move to home directory on your terminal and ensure you not on the root user

Change directory to home directory using the command: **`cd ~`**

**Note:** Please avoid running the commands directly from the root. Always run it from a user. Follow the below steps to exit If your terminal is running from root

* Use the **`exit`** command to come out of root user and then 
* Use **`cd ~`** command to change the directory to home directory.

### Step 2.3 Create a new directory on your terminal

Create a new directory using **`mkdir ~/bin`** command

### Step 2.4 Download Stader CLI

To manage your node, you will need Stader CLI (command-line interface). Download stader CLI using the commands provided in the below doc for your respective system architecture.

* **Wget link AMD64(Linux):** `wget https://staderlabs.com/eth/releases/stader-node-build/permissionless/v1.3.0/stader-cli-linux-amd64 -O ~/bin/stader-cli`
* **Wget link ARM64(Linux):** `wget https://staderlabs.com/eth/releases/stader-node-build/permissionless/v1.3.0/stader-cli-linux-arm64 -O ~/bin/stader-cli`
* **Wget link (MacOS** - **Intel):** `wget https://staderlabs.com/eth/releases/stader-node-build/permissionless/v1.3.0/stader-cli-darwin-amd64 -O ~/bin/stader-cli`
* **Wget link (MacOS - M1):** `wget https://staderlabs.com/eth/releases/stader-node-build/permissionless/v1.3.0/stader-cli-darwin-arm64 -O ~/bin/stader-cli`

**Unique checksums for verification and added security**

* **AMD64(Linux):**

  ```

### **Step 2.5 Steps to install wget if you don't have it on your system. If you have Wget already, you can skip this step**

To check if Wget is present on your system run the commands **`wget --version`**

* You will see the version details if the tools is installed
* You will see “command not found: wget” prompt if the tool is not installed.

**For  MacOS**

* Run the command and download brew: **`/bin/bash -c "$(curl -fsSL <https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh>)"`**
* Install wget using the command: **`brew install wget`**

**For Debian based systems like Ubuntu**

* Run the command and install wget **`sudo apt-get install wget -y`**

### Step 2.6 Give permission to run the downloaded application

Run this command **`chmod +x ~/bin/stader-cli`** to give permission to run the downloaded application

### Step 2.7 Restart the terminal and check the CLI version

After a successful restart of the terminal run the command **`~/bin/stader-cli --version`** to verify if the application was downloaded and running perfectly. A perfect download will display the latest CLI version.&#x20;

Latest CLI version: 1.3.0

### After successfully downloading your Stader node, proceed to Step 3 to install the node.
