Smokeping is used to monitor network latency and is used to send ping packets to configured stations, with 20 packets every 30 seconds. Based on the responses received, it can generate graphs with the availability of equipment or networks.

SmokePing is a latency measurement tool. The SmokePing Project can measure, store and display latency, latency distribution, and packet loss. SmokePing uses RRDtool to maintain a long-term data archive and develop beautiful graphics, waiving precise information on the status of each network connection.

SmokePing uses latency measurement plug-ins for seamless extension ability.

SmokePing comes with a smart alarm system. In addition to simple… read more +

PHP has a slightly turbulent history of packet management. This was to change in early 2012, when Composer and his brother, Packagist, were launched.

A package management system did not exist in the PHP world until early 2000, when Stig Bakken started the PEAR project as a result of the Tel Aviv talks at the PHP Developers Meeting.

The operating principle of the PEAR was to incorporate a manager directly into the PHP language runtime and install the desired dependencies using the command line. Dependencies were packaged in archives and used in projects by using the “include” or “require” instructions.

There are a lot of features people to choose a VPN over direct connection. Here are a few of the most commonly used ones:

1. Unlock content

Let’s suppose you live in Germany but want to watch a show on Hulu. Or, let’s say you are on holiday in Italy, but want to watch a series available only in the American version of Netflix. Without a VPN, you will not be able to access the website.
However, with a VPN, you can change your geographic location to make it look like you are in USA.
Also, a VPN can help you unlock other… read more +

Do you want to configure a Minecraft server but you do not know how to start? In this tutorial, I’ll try to explain how you can set up your Minecraft server.

First of all, you have to know that there are two large platforms: Vanilla and Bukkit.

Vanilla is the original, unmodified server. Bukkit created CraftBukkit, a modified customer on which you can install plug-ins to improve your server and player experience.

I’ll explain in this article how to set up a Bukkit server only.

The first step is to download the following:

– the latest version of Craftbukkit. If it not the right… read more +

Creating port forwarding rules to allow the game server connecting to the internet

If you’re using a Wi-Fi connection and you want to connect your Minecraft server to the internet you have to create a port that will redirect the users who connect through your IP to your computer (your server). Here are the steps you need to follow:

1. Connect to the your wifi router; the IP address should be written on the router. Write the IP address in the browser address bar. You’ll probably be asked to enter the username and the password which must also be written on… read more +

Let’s say you want to have one, two or more encrypted folders in your Linux user account. You want these folders to be hidden and can not be accessed by absolutely anyone, even those who know your root password. You want you and only you to have access to these folders.

Cryptkeeper does exactly what you want: manages encrypted folders; allows you to mount and remove encfs folders, change your password, and create new encrypted folders. It integrates seamlessly with Linux file managers.

Install Cryptkeeper in Ubuntu

Run the command:

sudo apt-get install cryptkeeper

Install Cryptkeeper in Arch Linux

Cryptkeeper is in AUR, so everyone… read more +

Below are a few specific terms for the Arch distribution. Some are found in other Linux distributions as well.

ABS

Arch Build System (ABS) is used to:

• Recompile a package for any reason.
• Create and install new source packages for programs without any available packages.
• Customize existing packages to suit your needs (enable or disable options, patching).
• Recompile the entire system, using the flags compiler, “a la FreeBSD” (With pacbuilder).
• Clean and install your own kernel.
• Copy kernel modules for the custom kernel.
• Easily compile and install a new, old, beta, or development version of a package by editing the version… read more +

There is an eternal controversy between Linux users: is there an antivirus needed in Linux?

In Windows, it is clear that without the antivirus, that PC is dead (even if its “owner” is not aware of it). The computer shuts itself down, strange windows with text that you do not understand, or tens/hundreds of windows that you can not shut down, emails are sent automatically – the reason for all these can be only one: the system has a virus. The main reason is that Windows is running.

Linux has very few viruses. A Linux virus is very hard to encounter;… read more +

If you use the bash command line regularly, you must have noticed that sometimes it’s rather inconvenient and unproductive to type long commands, not to mention that all sorts of options and parameters have to be memorized. Aliases can be used to shorten or rename long commands into shorter ones.

The alias allows a string to be replaced with a single word to simplify a command.

unalias 

Notes:
-p; displays the current values
-a; delete all aliases

If arguments are provided, an alias can be defined for each name whose value has been given. If no value is given,… read more +

JSON is an English acronym for JavaScript Object Notation and is a format for representation and the interchange of data between computer applications.

It is a human-readable text format used to represent objects and other data structures and is especially used to transmit structured data over the network, the process is called serialization. JSON is simpler, easier than XML. The elegance of the JSON format comes from being a subset of the JavaScript language (ECMA-262 3rd Edition), which is used alongside this language. Douglas Crockford created the JSON format and standardized it through RFC 4627. The type of media that… read more +
