In my article detailing the command line utilities available for configuring and troubleshooting network properties on Windows and Linux, I mentioned some Linux tools that, while still included and functional in many Linux distributions, are actually considered deprecated and therefore should be phased out in favor of more modern replacements.
Specifically, the deprecated Linux networking commands in question are: arp, ifconfig, iptunnel, iwconfig, nameif, netstat, and route. …..

While there are many network monitoring tools available for Linux, most of them monitor network traffic to and from your computer or a particular interface. However, there are times when you want to nail down a particular process that’s using up too much of the bandwidth, and there is a tool, dubbed NetHogs, that lets you do just that.
In this article, we will discuss the basics of NetHogs as well as the features it provides.

Nmap is short for Network Mapper. It is an open source security tool for network exploration, security scanning and auditing. However, nmap command comes with lots of options that can make the utility more robust and difficult to follow for new users.
The purpose of this post is to introduce a user to the nmap command line tool to scan a host and/or network, so to find out the possible vulnerable points in the hosts. You will also learn how to use Nmap for offensive and defensive purposes.

Have you ever encountered situations where one application dominated you all network bandwidth? If you have ever been in a situation where one application ate all your traffic, then you will value the role of the trickle bandwidth shaper application. Either you are a system admin or just a Linux user, you need to learn how to control the upload and download speeds for applications to make sure that your network bandwidth is not burned by a single application.

Files are generally assessed on their bitrate. A 320kbps MP3 is obviously better than a 128kbps version, right? Ordinarily, yes. But it’s not hard to bluff the bitrate and mislead listeners through “upscaling.” In fact, upscaling can sometimes damage audio quality.
Audio encoding is a complex process, and Stack Overflow user “vaxquis” provides an intricate explanation of how it works. If you find the subject interesting, his explanation is one of the clearest available.

The Linux monitoring systems are often used to follow system resources, such as CPU load, the amount of free RAM, network traffic statics or memory consumption. Which are ones from the most important tasks for every administrators. Furthermore, those tools notify the network administrator (via email, SMS or other alarms) when something interrupts or goes down which makes their life easier.
From those monitoring tools we will list the 7 most important in this article which will be described and identified by giving their features and mentioning their current version.
