How to Install dnsmasq on Fedora CoreOS Latest

dnsmasq is a lightweight DNS and DHCP server that is used for small networks. This tutorial will guide you through the installation process of dnsmasq on Fedora CoreOS Latest.

Prerequisites

Before proceeding with this tutorial, make sure that you have the following:

• A Fedora CoreOS Latest instance.
• A user account with sudo privileges.
• A terminal window for running commands.

Step 1: Update Packages

The first step is to update the package cache on your system. Run the following command in your terminal:

sudo dnf update -y

This will update all installed packages and their dependencies.

Step 2: Install dnsmasq

By default, dnsmasq is not available in the Fedora CoreOS Latest repositories. You will need to download it from the official website. To do so, follow these steps:

1. Open the dnsmasq download page at http://www.thekelleys.org.uk/dnsmasq/doc.html.
2. Find the latest version of dnsmasq, and copy the link to the download page.
3. Use the wget command to download the latest version of dnsmasq:

wget <dnsmasq download link>

4. Extract the downloaded package:

tar xvfz <dnsmasq package name>.tar.gz

5. Move to the dnsmasq extracted package directory:

cd <dnsmasq package name>

6. Compile and install dnsmasq:

make
sudo make install

Step 3: Configure dnsmasq

Now that dnsmasq is installed, you need to configure it properly. The main configuration file for dnsmasq is located at /etc/dnsmasq.conf. You can use any text editor to modify this file.

Here is an example configuration file for dnsmasq:

# Listen on the default DNS port
port=53

# Specify the domain name for your network
domain=mydomain.local

# Specify the IP addresses of your DNS servers
server=8.8.8.8
server=8.8.4.4

# Specify the IP address range for DHCP clients
dhcp-range=192.168.0.100,192.168.0.200,4h

# Assign a static IP address to a specific client
dhcp-host=<MAC address>,<IP address>

Replace <MAC address> with the MAC address of the client you want to assign a static IP address to and <IP address> with the desired IP address.

Step 4: Start dnsmasq

After configuring dnsmasq, you need to start the service. Run the following command in your terminal:

sudo systemctl start dnsmasq.service

You can also enable the service to start automatically during boot:

sudo systemctl enable dnsmasq.service

Conclusion

Congratulations! You have successfully installed and configured dnsmasq on Fedora CoreOS Latest. You can now use it as a lightweight DNS and DHCP server for your network.
