# Baremetal
## System Requirements
| CPU | OS | RAM | DISK |
|---|
| 4 vCPU | Debian 12/Ubuntu 22.04 | 8GB min 16GB Recommended | 2.5TB+ (SSD) |
{% hint style="info" %}
*The Fuse archival node has a size of 2.4TB on July 3rd, 2024*
{% endhint %}
### Pre-Requisites
```bash
sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y
sudo apt install -y git make wget gcc pkg-config libusb-1.0-0-dev libudev-dev jq gcc g++ curl libssl-dev screen apache2-utils build-essential pkg-config unzip
```
### Setting up Firewall
Set explicit default UFW rules
```bash
sudo ufw default deny incoming
sudo ufw default allow outgoing
```
Allow SSH
```bash
sudo ufw allow 22/tcp
```
Allow remote RPC connections with Fuse node
```bash
sudo ufw allow from ${REMOTE.HOST.IP} to any port 8545 8546
```
{% hint style="warning" %}
Not advised to allow all or unknown IP address to RPC port
{% endhint %}
Allow P2P Connections
```bash
sudo ufw allow 30303/tcp
sudo ufw allow 30303/udp
```
Enable Firewall
```bash
sudo ufw enable
```
To check the status of UFW and see the current rules
```bash
sudo ufw status verbose
```
## Building a Node on Fuse with Nethermind client
{% hint style="success" %}
Since **08.2022** Fuse is moving from OE client to [Nethermind](https://nethermind.io/). To bootstrap Fuse archive node this guide covers the steps on how to build Nethermind from source and configure it to run for Fuse Network
{% endhint %}
### Install .NET SDK
```bash
wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt update
sudo apt install -y apt-transport-https
sudo apt update
sudo apt install -y dotnet-sdk-8.0
```
### Download the Latest Nethermind Release Binary
Check [release binary](https://github.com/NethermindEth/nethermind/releases) page and take the following steps to download the latest Nethermind version:
Create a directory to store the binary and chain data (you might need `sudo`)
```bash
mkdir fuse-archive
```
Use `wget` to grab the latest [release binary](https://github.com/NethermindEth/nethermind/releases) archive and output it to the directory created in the previous step:
```bash
wget https://github.com/NethermindEth/nethermind/releases/download/1.27.0/nethermind-1.27.0-220b5b85-linux-x64.zip \
-O /root/fuse-archive/ nethermind-1.27.0-220b5b85-linux-x64.zip
```
Use `unzip` to extract downloaded archive
```bash
unzip nethermind-1.27.0-220b5b85-linux-x64.zip
```
### Configuing Nethermind client
#### Increase the maximum number of open files
```bash
sudo bash -c 'echo "nethermind soft nofile 100000" > /etc/security/limits.d/nethermind.conf'
sudo bash -c 'echo "nethermind hard nofile 100000" >> /etc/security/limits.d/nethermind.conf'
```
#### Download chainspec file for Fuse
```bash
mkdir -p /root/fuse-archive/chainspec
wget https://raw.githubusercontent.com/fuseio/nethermind-client/refs/heads/production/src/Nethermind/Chains/fuse.json
```
The contents of the fuse.json file should be like this:
