Introduction Managing SSL certificates for multiple websites can be complicated and time-consuming, especially when each domain requires its own certificate. A Multi-Domain SSL certificate, also called a Subject Alternative Name (SAN) certificate or Unified Communications Certificate (UCC), makes this easier by letting you secure several domains with a single SSL certificate. This method lowers the administrative burden and helps organizations manage SSL security more effectively. In this article, we will look at what a Multi-Domain SSL certificate is, how to create a CSR with Subject Alternative Names (SANs), and how to install the certificate for multiple domains on a cPanel server. What is Multi-domain SSL? A multi-domain certificate (also known as a SAN certificate or Unified Communications Certificate (UCC)) is …

Introduction If your website uses Incapsula and visitors see a “Site Unreachable” error, the issue is usually due to firewall or traffic-filtering settings. Incapsula works as a reverse proxy and web application firewall. It directs all website traffic through its secure network before it reaches your server. This improves security and performance, but misconfigured firewalls or rate-limiting systems can flag Incapsula traffic as suspicious and block legitimate requests. In this blog, we will explain why the “Site Unreachable via Incapsula” error occurs and how to configure your server to allow traffic from Incapsula’s IP ranges. Site Unreachable Error This error may occur if the website uses Incapsula for maintaining traffic.Incapsula provides every website, regardless of its size, with an enterprise-grade …
Ever since after the up gradation of WHM to higher versions, there can be many issues of lost or unlisted addon/parked domains in Cpanel. The domains will be present in /etc/userdomains, but still fails to be seen in the email account creation tab in Cpanel. This is mainly beacuse of the XDNS entries in /var/cpanel/users/<cpanel_username> If your required domains are marked as XDNS, then rename XDNS to DNS of all the required domain entries. After this you have to run the following script to update the userdomains #scripts/updateuserdomains After running this script, the domains will be found available for new account creation.

The Precision Time Protocol (PTP) is a network protocol used to synchronize clocks across devices in a computer network. It is designed to deliver very high accuracy, especially in environments where precise timing is critical. PTP typically operates over Ethernet networks and achieves its best accuracy on well-engineered local area networks (LANs) that support hardware timestamping. On such networks, PTP can synchronize clocks with sub-microsecond accuracy. The PTP timescale is expressed in seconds and nanoseconds, allowing extremely fine-grained time measurement. IEEE 1588 and PTP Usage PTP is defined by the IEEE 1588 standard. It is widely used in systems that require precise timing, such as: Industrial automation Measurement and control systems Telecommunications Scientific and engineering applications These environments benefit from …
