A buffer is a space in memory (typically RAM) that stores binary data. In Node.js, we can access these spaces of memory with the built-in Buffer class. Buffers are useful when using JavaScript to interacting with binary data, usually at lower networking levels. In this tutorial, you will use the Node.js REPL to create buffers, read from buffers, write to and copy from buffers, and use buffers to convert between binary data and data encoded with ASCII and UTF-8.

In this tutorial, we will go over how to set up an internal DNS server, using the BIND name server software (BIND9) on CentOS 7, that can be used by your Virtual Private Servers (VPS) to resolve private host names and private IP addresses. This provides a central way to manage your internal hostnames and private IP addresses, which is indispensable when your environment expands to more than a few hosts.
In this tutorial you will learn how to configure Suricata’s built-in Intrusion Prevention System (IPS) mode. When you enable IPS mode, Suricata can actively drop suspicious network traffic in addition to generating alerts. Once you know which signatures you would like to use in IPS mode, you’ll convert their default action to drop or reject traffic. With your signatures in place, you’ll learn how to send network traffic through Suricata using the netfilter NFQUEUE iptables target.
GlusterFS is a technology that allows you to create pools of storage that are accessible from the network. Using this software, in this article we will discuss how to create redundant storage across multiple servers in order to ensure that your data is available regardless of if one server goes down.
Syncthing is an open source file syncing protocol and tool that can be used to synchronize directories between remote servers. In this guide, we will discuss how to install and configure this service to sync files between two Ubuntu 14.04 servers.
