How to Install OpenAFS on Arch Linux

OpenAFS is a powerful and versatile distributed file system that allows clients to access and share data over a network. If you're running Arch Linux and need to install OpenAFS, this tutorial will guide you through the process.

Prerequisites

Before you begin, you should have the following:

Step 1: Update the System

First, update your Arch Linux system by running the following command:

sudo pacman -Syu

This will ensure that your system is up to date and that you have the latest security patches installed.

Step 2: Install Required Packages

Next, install the packages required for OpenAFS by running the following command:

sudo pacman -S openafs-modules-dkms openafs-client krb5

This will install the OpenAFS kernel modules, the OpenAFS client, and the Kerberos authentication system.

Step 3: Configure OpenAFS

Once the required packages are installed, you'll need to configure OpenAFS to work with your system.

3.1: Set Up Kerberos

Before you can use OpenAFS, you'll need to set up Kerberos authentication. To do this, run the following command:

sudo kinit your-kerberos-username@YOUR-REALM

Replace your-kerberos-username and YOUR-REALM with your actual Kerberos credentials.

3.2: Modify AFS Configuration Files

Next, you'll need to edit the OpenAFS configuration files.

3.3: Start the OpenAFS Client

Finally, start the OpenAFS client by running the following command:

sudo systemctl start openafs-client.service

Step 4: Verify Installation

To verify that OpenAFS is installed and working correctly, run the following command:

klist

This should display your Kerberos tickets, indicating that the authentication system is working correctly.

Next, run the following command:

fs listacl /

This should list the access control list for the root directory of your AFS file system.

If both commands executed successfully, congratulations! You've successfully installed and configured OpenAFS on Arch Linux.

Conclusion

OpenAFS is a versatile and powerful file system that can be used to share data over a network. By following the steps in this tutorial, you should be able to install and configure OpenAFS on your Arch Linux system.
