In the past I’ve posted an article about Anonymous browsing with Tor that can be useful when you use your favorite browser and you wish to stay anonymous thanks to the Tor software.

Tor (short for The Onion Router) is a system intended to enable online anonymity. Tor client software directs internet traffic through a worldwide volunteer network of servers to conceal a user’s location or usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult to trace Internet activity, including “visits to Web sites, online posts, instant messages and other communication forms”, back to the user and is intended to protect users’ personal freedom, privacy, and ability to conduct confidential business by keeping their internet activities from being monitored.

Today I want to show some simple uses of the command torify that can be used from the Linux terminal.

Both for a real server, VPS or just your desktop is useful to know which IP address your Linux system is using , this can be easily seen with some command if you are directly connected to Internet via a modem or a public IP of your company, but sometimes you are behind a router, a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks, and at home it’s used to “share” your ADSL that usually has 1 public IP among all your devices, that will get each a private IP. For example at my home I’ve an ADSL Wi-Fi router that I use to get Wi-Fi connection to my 3 PC, 1 smartphone and 1 tablet (android), a printer and my kindle, every device has a private IP , it’s called private because it’s not visible on the public network that can only “see” the IP of my Wi-Fi router, but now let’s see how to check your IP on your Linux computers.

one late night

One Late Night is a short immersive horror-game experience, released for free for Linux, Mac and WIndows, the basic idea of this game is to put the gamer in a situation similar to something that it could have been in, and also the scenario is just an office, with standard things (and an android figurine), the idea is that the players will relate themselves to the game setting and scenario and become immersed. Even if you can’t relate to the game storyline, you will still get a good experience.

The main (and the only alive) character is an unnamed graphic designer employee, working late one night at the office, until strange things start to happen.
Soon you’ll see strange message on your computer screen and you’ll start to see scaring thing in your office.

When something goes wrong on your Linux server or desktop, is important to understand which process is taking all the resources, in the past I’ve published some information about top and htop, two great tools to have a general overview of your system with just a glance, but sometimes you need to gather more information of a particular process and for this task the command pidstat is perfect.

Pidstat is a statistics report tool for Linux which is part of the sysstat utilities. The pidstat command is used for monitoring individual tasks currently being managed by the Linux kernel. It writes to standard output activities for every task selected with option -p or for every task managed by the Linux kernel if option -p ALL has been used. Not selecting any tasks is equivalent to specifying -p ALL but only active tasks (tasks with non-zero statistics values) will appear in the report.
You can use PID’s and even regular expressions on the process names to filter them out.

This is a new and interesting project that could be really useful both for companies that for private users, Guacamole is an HTML5 remote desktop gateway that provides access to desktop environments using remote desktop protocols like VNC and RDP. A centralized server acts as a tunnel and proxy, allowing access to multiple desktops through a web browser.

Be aware that Guacamole is only a remote desktop gateway, and cannot access your desktop’s display without a remote desktop server of some kind to connect to. Guacamole does not contain its own VNC or RDP server, it’s a java based program so it’s distributed as a .war package.

The client requires nothing more than a web browser supporting HTML5 and AJAX.
