Changing Wazuh IP Address

Introduction

In this blog post we will change the IP address of a Wazuh machine. This will keep the IP address static even after a reboot. So now we will walk through the steps to configure a static IP address for the Wazuh machine.

Prerequisites

Before we begin, make sure you have the following prerequisites in place:

A Wazuh machine running on your network.
Access to the Wazuh machine with administrative/root privileges.
Basic knowledge of Linux command line and network configuration.

Steps

Make sure the wazuh machine is turned on and log on to the machine.

Step 1: Check the current version of the machine.

                            
                                    Bash
                                
                                        cat /etc/os-release

Bash
`cat /etc/os-release`

This command will display the operating system information.
look for the line that starts with "Pretty_Name" to see the current version of the OS. Pretty_Name="Amazon Linux 2023.x.xxxxxxxx"
Once you have the current version information, and matches the expected version, you can proceed to the next step.

Step 2: Configuring the IP address

Login:
- Login to the wazuh machine.
System Updates:
- Ensure that the Wazuh instance is up to date by running the latest updates.
Configuration:
- Navigate to the following path to edit the network configuration file:
```
/etc/systemd/network
```
- Create a new file "05-static-eth0.network" using the command:
```
sudo vim /etc/systemd/network/05-static-eth0
```
  Here im using vim editor you can use any editor of your choice.
- Add the following configuration to set a static IP address:
```
[Match]
Name=eth0

[Network]
Address=192.168.0.200/24
Gateway=192.168.0.1
DNS=8.8.8.8
DNS=1.1.1.1
```
save and exit the file. press "ESC" and type ":wq" to save and exit the file.
Restart the machine to apply the changes using the command:
```
sudo reboot
```
This will restart the Wazuh machine, and upon reboot, it will have the new static IP address configured.
SSH into the machine using the new IP address to verify that the changes were applied successfully.
