Get your private and public IP from the Linux terminal

Jan 272013

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.

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.
