Country Name (2 letter code) [GB]:
State or Province Name (full name) [Berkshire]:
Locality Name (eg, city) [Newbury]:
Organization Name (eg, company) [My Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server’s hostname) []:<make sure it matches exactly with your domain>

Create the certificate without passphrase if you dont want passphrase to be prompted for every webserver restart.

Upload the CSR to the Certificate Authority and get the signed certificate and save it as domain_name.crt. If it is from verisign get both intermediate certificates and add it to a file (eg: intermediate.ca.crt)

In virtual host configuration

Restart webservice and verify the certificate, you may use the verisign cert checker (https://ssl-tools.verisign.com/#certChecker)

Configure Rack Tables:

Edit the inc/secret.php

Set :

$user_auth_src = 'httpd';
$require_local_account = FALSE;

NOTE: to get the logout working properly make sure the Apache AuthName matches with the one configured for Rack tables authentication.

Step 1: Ensure IPv6 Support in the Kernel

Before diving into the configuration, you need to confirm that IPv6 support is enabled in your kernel. Most modern kernels have IPv6 support enabled by default. However, it’s always a good idea to double-check.

• To do this, open the file /etc/modprobe.conf and comment out the following lines if they exist:

Step 2: Enable IPv6 Networking

The next step is to enable IPv6 networking. To do this:

• Open the file /etc/sysconfig/network.
• Add or modify the following line to read:

Step 3: Configure the IPv6 Address

To configure your IPv6 address:

• Edit the appropriate network configuration file. For example, if you’re using Ethernet, you would typically edit /etc/sysconfig/network-scripts/ifcfg-eth0. If you’re using bond interfaces, the same principles apply.
• Add or modify the following lines to specify your IPv6 address details:

Step 4: Restart the Network

After making these changes, restart your network to apply the new IPv6 configurations. Your system should now be assigned an IPv6 address, and you’ll be ready to utilize IPv6 networking.

Step 5: Software Configuration

Most Linux software works seamlessly with IPv6. However, for certain services like Apache, you may need to make some adjustments. For Apache, ensure you do the following:

• Add the IPv6 listen address to your Apache configuration.
• Enable name virtual host for IPv6 addresses if necessary.

Step 6: Testing IPv6 Connectivity

You can verify your IPv6 connectivity by using the ping6 command. For instance, to test your connection to Google’s IPv6 address, you can run:

This command will help you confirm that your system is effectively communicating over IPv6.
