There are several online tools to test your connection speed, one of them is the Speed Test by Ookla and the Google speed test. Tools like the latter are certainly useful and fast if we need to test the speed of the network to which the computer is connected Read more
Your internet, in blogs, in mail groups, in the forums and on social networks we often read that Linux is absolutely safe and impenetrable to attacks.

A NAS is not (or it is no longer) just a habit for geeks, but a tool that Read more
The goal today is to reduce the stress on the LAN and free up some of the computational resources of the router. There will be no substantial differences in speed or not using Jumbo Frames, but this way we can reduce the time required for file transfer. (more…)
In today's article we deal with the network, especially Wi-Fi. With Linux we have several command line programs that allow us to monitor and manipulate networks. What follows is a set of Linux tools used to monitor it. We will examine the speed, bitrate, the Read more
As we download from the internet? Gigabytes and gigabytes of data, personally mostly iso or software updates (this is. the kernel is a beautiful brick). And sometimes it happens that when we start the download speed is pretty good, but after some time we see it slow down, halved, sometimes Read more
Many networks have the advantage of Windows “Active Directory” and local domains, an important priority within the company if. Most of the Windows shares using the solution “WORKGROUP“, the default choice when creating a shared network (to share files or printers). Most users have Read more
There are standards of behavior for crawlers in the network (the bot, or even spider) for content indexing. I am not referring to the file “.htaccess“, that is used to configure the webserver, I'm talking about the file “robots.txt“.
