# Step 2: Download Stadernode

### Step 2.1 Open your system ports[​](https://www.staderlabs.com/docs-v1/Ethereum/Node-operator/permissionless-node-operator/node-registration-and-adding-validators/step-2-download-stader-node#step-21-open-your-system-ports) <a href="#step-21-open-your-system-ports" id="step-21-open-your-system-ports"></a>

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[​](https://www.staderlabs.com/docs-v1/Ethereum/Node-operator/permissionless-node-operator/node-registration-and-adding-validators/step-2-download-stader-node#step-22-move-to-home-directory-on-your-terminal-and-ensure-you-not-on-the-root-user) <a href="#step-22-move-to-home-directory-on-your-terminal-and-ensure-you-not-on-the-root-user" id="step-22-move-to-home-directory-on-your-terminal-and-ensure-you-not-on-the-root-user"></a>

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

{% hint style="danger" %}
**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.
  {% endhint %}

### Step 2.3 Create a new directory on your terminal[​](https://www.staderlabs.com/docs-v1/Ethereum/Node-operator/permissionless-node-operator/node-registration-and-adding-validators/step-2-download-stader-node#step-23-create-a-new-directory-on-your-terminal) <a href="#step-23-create-a-new-directory-on-your-terminal" id="step-23-create-a-new-directory-on-your-terminal"></a>

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

### Step 2.4 Download Stader CLI[​](https://www.staderlabs.com/docs-v1/Ethereum/Node-operator/permissionless-node-operator/node-registration-and-adding-validators/step-2-download-stader-node#step-24-download-stader-cli) <a href="#step-24-download-stader-cli" id="step-24-download-stader-cli"></a>

**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/v1.6.5/stader-cli-linux-amd64 -O ~/bin/stader-cli`
* Wget link ARM64(Linux): `wget https://staderlabs.com/eth/releases/stader-node-build/permissionless/v1.6.5/stader-cli-linux-arm64 -O ~/bin/stader-cli`
* Wget link (MacOS - Intel): `wget https://staderlabs.com/eth/releases/stader-node-build/permissionless/v1.6.5/stader-cli-darwin-amd64 -O ~/bin/stader-cli`
* Wget link (MacOS - M1): `wget https://staderlabs.com/eth/releases/stader-node-build/permissionless/v1.6.5/stader-cli-darwin-arm64 -O ~/bin/stader-cli`

**Unique checksums for verification and added security**\
**Verify the checksums using the following command:** `sha256sum ~/bin/stader-cli`

```
AMD64(Linux): 153d4b004c9219d7e12ec046a5901300b87438edeb1e4162148d280f3ea0cf73
ARM64(Linux): 5f58a97fb64941590cc34526fbb4c58a4cc380da4458f68b9eaf8f30be7d17e5
MacOS-Intel: 2dd6dd14ecc4192a5b35624bf41f1c18e688d94206c2ba6a1bdae1ad9ff1e887
MacOS-M1: cb2687840c3820a213ed5d7c6be74d34697f04028512504c5ac9c08eb0dc8f3d
```

### **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**[​](https://www.staderlabs.com/docs-v1/Ethereum/Node-operator/permissionless-node-operator/node-registration-and-adding-validators/step-2-download-stader-node#step-25-steps-to-install-wget-if-you-dont-have-it-on-your-system-if-you-have-wget-already-you-can-skip-this-step) <a href="#step-25-steps-to-install-wget-if-you-dont-have-it-on-your-system-if-you-have-wget-already-you-can-sk" id="step-25-steps-to-install-wget-if-you-dont-have-it-on-your-system-if-you-have-wget-already-you-can-sk"></a>

**To check if Wget is present on your system run the command: `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.

**Installing wget on 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`**

**Installing wget on 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[​](https://www.staderlabs.com/docs-v1/Ethereum/Node-operator/permissionless-node-operator/node-registration-and-adding-validators/step-2-download-stader-node#step-26-give-permission-to-run-the-downloaded-application) <a href="#step-26-give-permission-to-run-the-downloaded-application" id="step-26-give-permission-to-run-the-downloaded-application"></a>

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[​](https://www.staderlabs.com/docs-v1/Ethereum/Node-operator/permissionless-node-operator/node-registration-and-adding-validators/step-2-download-stader-node#step-27-restart-the-terminal-and-check-the-cli-version) <a href="#step-27-restart-the-terminal-and-check-the-cli-version" id="step-27-restart-the-terminal-and-check-the-cli-version"></a>

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.

**Latest CLI version: v1.6.5**

### After successfully downloading your Stader node, proceed to [Step 3](/stader/ethereum/node-operator/permissionless-node-operator/node-registration-and-adding-validators/step-3-install-stadernode.md) to install the node. <a href="#after-successfully-downloading-your-stader-node-proceed-to-step-3-to-install-the-node" id="after-successfully-downloading-your-stader-node-proceed-to-step-3-to-install-the-node"></a>
