## 1. VirtualBox Download

To begin, download VirtualBox.

## 2. RHEL (Red Hat Enterprise Linux) OS Download

Since CentOS reached its End of Life (EOL), it's recommended to use RHEL.

- Visit [RHEL Downloads](https://developers.redhat.com/products/rhel/download) (version 9.4 as of 2024.11.02).
- To use RHEL for free, register for an Individual Developer Subscription. There is no cost for registration.

## 4. Connect to the VM Using Putty
- To connect to the VM, follow the steps below:

### 4-1. Verify VM Settings in VirtualBox

```
1. Open VirtualBox, select the VM, and go to **Settings**.
2. Navigate to the **Network** tab, and set **Adapter 1** to **NAT**.
3. Set up port forwarding rules:

   - **Name**: Enter a name (e.g., SSH).
   - **Host Port**: Set an unused port on your host (e.g., 9999).
   - **Guest Port**: Enter 22 (default SSH port).

   Example:
   "putty -(9999 port)> VM -(22 port)> Linux"

```

### 4-2. Internal VM Configuration
- Download and start the SSH server

```
sudo yum install -y openssh-server  # Install SSH server
sudo systemctl start sshd           # Start SSH server
sudo systemctl enable sshd          # Enable SSH to start on boot
```

- Firewall configuration
```
sudo firewall-cmd --permanent --add-port=22/tcp
sudo firewall-cmd --reload

```

- Modify SSH configuration
```
sudo vi /etc/ssh/sshd_config

Edit the file as follows (In VI, find the term with '/term', press 'a' to edit, then press ESC and type ':w' to save)

#PermitRootLogin $value -> PermitRootLogin yes (necessary if the ID is root)
#PasswordAuthentication yes -> PasswordAuthentication yes
(Remove # and change to yes)

Restart SSH to apply changes:
sudo systemctl restart sshd

```
- Connection Verification
