Here are some free, open-source, and useful network tools for Linux:

1) tcpdump is a common packet analyzer that runs under the command line. It allows the user to intercept and display TCP/IP and other packets being transmitted or received over a network to which the computer is attached. Distributed under the BSD license. The tcpdump command has a lot of advanced features, most of which revolve around filtering and finding a needle in a haystack of packets. If you run tcpdump on a remote machine, your screen will be flooded with all the ssh traffic between your client and the remote machine. To get started without having to learn too much about how tcpdump filtering works, run the following command:

Here are some tricks and best practices for a setup that will improve your throughput without forcing you to upgrade your hardware.

Let’s start with a look at the Linux operating system, MySQL database, and nginx web server. Later we’ll get to PHP, some setup and plugin work with WordPress itself, and Varnish Cache, a web application accelerator.

In these days I had to download a lot of files from a remote FTP server, the best solution in cases like this one is to login on the remote server and do a zipped archive of all the files (for this use tar -zcvf archivename.tgz /path/to/archive/) , in this way you’ll have to download just 1 file that is also been compressed and FTP can do perfectly this.

Article By Giuseppe Sanna

There are many articles covering the subject of trashware. You do not know what is this phenomenon? Trashware is when you use a PC, perhaps obsolete, to do something useful, especially using Open Source software with low requirements, with regard to system resources. Today we will not speak about media center or navigation station. We’ll talk about something much more concrete and useful! A download center … You really got it right! You will use your computer from the network to download all the files you want using the system “.torrent”. Naturally download only legal files, this is clear.
