DNSCrypt is a protocol for securing communications between a client and a DNS resolver, preventing spying, spoofing or man-in-the-middle attacks. To use it, you’ll need a tool called dnscrypt-proxy, which “can be used directly as your local resolver or as a DNS forwarder, authenticating requests using the DNSCrypt protocol and passing them to an upstream server“.

Firewall is an important and necessary tool to protect us from the unsecure Internet. Most of the modern OSes come with a built-in firewall, but the problem is that few people know of its existence and only a few know how to configure it.
Windows is no different. By default, it comes with a decent built-in firewall which is capable of controlling all the incoming and outgoing traffic. This built-in Windows firewall is a bit clunky with a not-so-friendly user interface and complex rules, though it does gives you plenty of control on overall rules like blocking, restricting, whitelisting, etc. In this article, we are going to show you how to create advanced firewall rules in Windows firewall to block an application from accessing the Internet.

A kernel panic is an action taken by an operating system upon detecting an internal fatal error from which it cannot safely recover. The term is largely specific to Unix and Unix-like systems; for Microsoft Windows operating systems the equivalent term is “stop error” (or, colloquially BSOD “Blue Screen of Death”).

The default [is] to wait, so if this happen on one of your servers and you don’t notice it all its services could stay down for some time, while using an automatic reboot the problem could be solved quickly.
We can configure a directive that will automatically reboot the system when a kernel panic is detected.

Unlike Windows-based computers, Macs usually do not come with multiple hard-drive partitions. It is just a single partition that you see when you first boot your Mac. Though there is no harm using your Mac with a single partition, it is highly recommended that you have at least two partitions on your machine. This will let you store your important files on one partition when the other one is being formatted. It is also helpful if you plan to install another OS beside your Mac OS. Regardless of your reasons, here’s how you can do it.

DNS, stands for Domain Name System, translates hostnames or URLs into IP addresses. For example, if we type www.unixmen.com in browser, the DNS server translates the domain name into its associated ip address. Since the IP addresses are hard to remember all time, DNS servers are used to translate the hostnames like www.unixmen.com to 173.xxx.xx.xxx. So it makes easy to remember the domain names instead of its IP address.
This detailed tutorial will help you to set up a local DNS server on your CentOS 7 system. However, the steps are applicable for setting up DNS server on RHEL and Scientific Linux 7 too.

We have all lost files. You think a file is in a certain directory and yet when you go looking for it, you can’t find it. Most desktop-based Linux distributions have a way to find files from the desktop, but you can also find files from the command line using the
findcommand.

Mac: One of the nice things about OS X is the fact you can easily make tiny little apps using basic lines of codes. Actually turning those little snippets into an app outside of Terminal requires a compiler though. App Factory eases that process by creating the app for you.

Renaming files is not a particularly advanced operation; as long as it’s done on a small number of files, it usually doesn’t require special tools. However, when there’s an entire folder of photos from last year’s vacation waiting to be renamed, it might be wise to consider some time-saving tricks or apps.
