You might have seen some of the sites showing you the information like “Your IP address is 127.0.0.1 ” or “You are using Firefox browser” etc. Its really easy to display or get these user or visitor information using PHP codes. Here in this post, we will write a simple php code for displaying a visitor’s IP address, browser info and where that user came from (Http_Referrer i.e from which url the user clicked to get to your current page).
For a long time we, as developers, fought with it: sometimes with good results, sometimes not, but we thought we were happy.
Unfortunately, the web goes fast and many of these solutions was getting old too quickly.
Later on, a group of people realised that it was time to stop fighting with the “problem” and try to embrace it. The result of that epiphany is called JSON Web Token (JWT for short) and here we will try to tell its story…
There is something very powerful about automating even the little things. We sometimes think as automation as the simple maths of saving a given number of minutes/seconds by a given number of times a day but the compound effect is much greater.
As you will be setting up more automation for your deployments, you will run into and solve problems many times more critical than saving a few minutes a week.
Let’s Encrypt is a Certificate Authority (CA) that provides an easy way to obtain and install free TLS/SSL certificates, thereby enabling encrypted HTTPS on web servers. It simplifies the process by providing a software client, Certbot, that attempts to automate most (if not all) of the required steps. Currently, the entire process of obtaining and installing a certificate is fully automated on both Apache and Nginx.
With the increasing demand for higher bandwidth, multiple types of transceiver modules are designed for data transmission, including GBIC, SFP, SFP+, QSFP and so on. Well, what do GBIC, SFP, SFP+ and QSFP stand for? Among them, SFP has been used in popularity for over 15 years.
The fiber optic market is filled with options that will improve your connectivity in a matter of seconds. When it comes to transceivers, there are multiple types of modules you can choose from (GBIC, SFP, SFP+, QSFP, X2, CFP, and others), no matter if you opt for an older or newer fiber optic technology. Still, what answers to your needs the best?
DevOps engineers and systems administrators share a range of common tasks but there are also some fundamental differences that IT professionals and hiring managers should be aware of.
Employers should be wary of systems administrators who claim they can do anything a DevOps engineer can. While the two roles are similar, they are not identical.
In this article, we’ll aim to provide some clarity on the issue by highlighting the cause of confusion and the main points of distinction between the two roles.
Apache’s mod_rewrite module lets you rewrite URLs in a cleaner fashion, translating human-readable paths into code-friendly query strings. It also lets you rewrite URLs based on conditions.
An .htaccess file lets you create and apply rewrite rules without accessing server configuration files. By placing the .htaccess file in the root of your web site, you can manage rewrites on a per-site or per-directory basis.
In this tutorial, you’ll enable mod_rewrite for Apache in Ubuntu 18.04
Ansible is a free and open source automation tool that allows system administrators to configure and control hundreds of nodes from a central server without the need of installing any agents on the nodes.
It relies on the SSH protocol to communicate with the remote nodes. Compared to other management tools such as Puppet and Chef, Ansible comes out as the favorite due to its ease of use, and installation.
In this tutorial, you will learn how to install and configure the Ansible automation tool on RHEL/CentOS 8 Linux distribution.
