How to Install CoreDNS on NetBSD

This tutorial will guide you through the process of installing CoreDNS, a flexible and extensible DNS server, on NetBSD.

Prerequisites

Before proceeding with the installation, ensure that you have the following prerequisites:

• NetBSD installed on your machine
• Superuser access to the system
• Internet connectivity

Step 1: Install Go

To install CoreDNS, you need to have Go installed on your system. To install Go on NetBSD, follow these steps:

1. Open a terminal on your NetBSD system.
2. Run the following command to update the package repository:

pkgin update

3. Next, we need to install the required packages using the following command:

pkgin install go

4. Once the installation is complete, verify the installation by checking the Go version using the following command:

go version

You should see the Go version installed on your system.

Step 2: Download CoreDNS

After installing Go, we need to download the latest version of CoreDNS from the official website. To download CoreDNS, follow these steps:

1. Open your web browser and visit the CoreDNS website at https://coredns.io/.
2. Click on the "Download" button to go to the download page.
3. On the download page, select the latest version of CoreDNS for NetBSD and click on the link to download the tarball.

Step 3: Extract the Tarball

After downloading the tarball, we need to extract it to a suitable directory. Follow these steps to extract the tarball:

1. Open a terminal on your NetBSD system.
2. Navigate to the directory where you downloaded the tarball.
3. Use the following command to extract the tarball:

tar xzf coredns-*.tar.gz

This command will extract the tarball to a new directory named "coredns-*" (where * is the version number).

Step 4: Build CoreDNS

After extracting the tarball, we need to build CoreDNS using Go. Follow these steps to build CoreDNS:

1. Open a terminal on your NetBSD system.
2. Navigate to the "coredns-*" directory.
3. Use the following command to build CoreDNS:

make

This command will build CoreDNS by running the Go build process.

Step 5: Install CoreDNS

After building CoreDNS, we need to install it on our system. Follow these steps to install CoreDNS:

1. Open a terminal on your NetBSD system.
2. Navigate to the "coredns-*" directory.
3. Use the following command to install CoreDNS:

sudo make install

This command will install CoreDNS on your system.

Step 6: Configure CoreDNS

After installing CoreDNS, we need to configure it to run as a DNS server. Follow these steps to configure CoreDNS:

1. Open a terminal on your NetBSD system.
2. Navigate to the "/usr/local/etc/coredns" directory.
3. Edit the "Corefile" file using your preferred text editor.
4. Uncomment the "example.org" section and modify it to suit your DNS requirements.
5. Save and close the file.

Step 7: Start CoreDNS

After configuring CoreDNS, we need to start it to serve DNS requests. Follow these steps to start CoreDNS:

1. Open a terminal on your NetBSD system.
2. Use the following command to start CoreDNS:

sudo coredns -conf /usr/local/etc/coredns/Corefile

This command will start CoreDNS and load the configuration file.

Conclusion

Congratulations! You have successfully installed and configured CoreDNS on your NetBSD system. You can now use CoreDNS to serve DNS requests for your network.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
