SAN VS. NAS: A Comparison

Reading Time: 4 minutes

Storing data in a safe, secure, and reliable manner has always been a significant concern for those working within a distributed networked environment. In this article, we will be exploring two specific methods of managing, preserving, and archiving information. These methods include using the SAN or Storage Area Network or the NAS or Network Attached Storage protocols. Both protocols provide a networked storage solution, but the main difference is in the approach and implementation. A NAS device is usually a single storage unit, while a SAN is typically a network cluster of several devices. Sometimes both these methods are employed and combined into a single medium called a Unified SAN

How to Install and Configure Nmcli

Reading Time: 4 minutes

What is nmcli?

nmcli stands for Network Management Command-Line Interface, and is a tool for managing the NetworkManager application and reporting on the status of the network. It can be utilized as a substitution for nm-applet or other similar graphical clients. nmcli is used to display, create, delete, edit, activate, deactivate network connections, and control and display network device status.

Typical uses include:

  • Scripts: Utilize NetworkManager via nmcli rather than managing network connections manually. nmcli supports a terse output format that is healthier fitted to the script process. Note that NetworkManager can even execute scripts, referred to as “dispatcher scripts,” responding to network events.
  • Servers, headless machines, and terminals: nmcli tool can be used to control NetworkManager without a graphical user interface, including creating, deleting, editing, starting and stopping network connections as well as viewing network status.

How To Change the SNMP Port on CentOS

Reading Time: 2 minutes

Introduction

SNMP, or Simple Network Management Protocol, is widely used to communicate with and monitor network devices, servers, and more, all via IP. In the previous article, we installed an SNMP agent on a CentOS 6.5 server. This agent allows for the collection of data from our server and makes the information available to a remote SNMP manager. To add a little security, we’ll now change the port that SNMP listens on.

How To Install and Configure SNMP on CentOS

Reading Time: 3 minutes

Introduction

SNMP, or Simple Network Management Protocol, is widely used to communicate with and monitor network devices, dedicated servers, and more, all via IP. In this case, we’ll be installing an SNMP agent on a CentOS VPS server, which will allow for collection of data from our server, and make the information available to a remote SNMP manager.

Pre-Flight Check

  • These instructions are intended for installing SNMP and doing a very basic configuration.
  • I’ll be working from a Liquid Web Core Managed CentOS 6.5 server, and I’ll be logged in as root.

What is localhost?

Reading Time: < 1 minutelocalhost is a networking term; it’s the hostname for the loopback network interface of whichever server it’s said in reference to (meaning every server has a ‘localhost‘). The loopback interface bypasses any local network interface hardware, and serves as a method to connect back to the server itself. The term localhost is used often in both networking and in server administration.

IPv4 Localhost

The IPv4 address for localhost, or the loopback network interface, is 127.0.0.1.

IPv6 Localhost

The IPv6 address for localhost, or the loopback network interface, is ::1.
