How to Install Virtualmin on OpenBSD

Virtualmin is a powerful and user-friendly web hosting control panel that manages multiple domains, email accounts, and other web hosting services. Here's how to install it on OpenBSD:

Step 1: Install Required Dependencies

Virtualmin requires several software dependencies to run properly. You can install them using the following command:

$ sudo pkg_add perl bash wget

Step 2: Download and Install Virtualmin

1. Go to the Virtualmin website at http://www.virtualmin.com/download.html and download the latest .sh installer file for OpenBSD.

2. Use the following command to make the file executable:

$ chmod +x virtualmin-install.sh

3. Run the installer using the following command:

$ sudo ./virtualmin-install.sh

4. The installer will prompt you for some input during the installation process. Answer the questions according to your preferences.

5. Once the installation is complete, you can access Virtualmin at https://your-server-ip:10000.

Step 3: Configure Firewall Rules

By default, OpenBSD comes with a host-based firewall called pf. You will need to configure some firewall rules to allow traffic to pass through to the Virtualmin control panel.

1. Open the firewall configuration file using the following command:

$ sudo vi /etc/pf.conf

2. Edit the file to include the following lines:

pass in quick proto tcp from any to your-server-ip port 10000
pass out quick proto tcp from your-server-ip to any port 10000

3. Save the file and exit.

4. Reload the pf firewall rules using the following command:

$ sudo pfctl -f /etc/pf.conf

That's it! You have successfully installed Virtualmin on OpenBSD and configured firewall rules to access it.

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!
