Previously, I showed you the way to generate a public/private SSH key so you can connect to your remote host securely. The method that we used is via the terminal, which can be rather unfriendly (and scary) to the Linux newbies. Here is an easier method of setting up your public/private SSH key, with a GUI.
I am not sure about any other distro (as I have not tried them all), but in Ubuntu, the default keyring manager (also known as seahorse) comes with the ability to create public/private SSH key and help you set it up in the server.

If you are using SSH frequently to connect to a remote host, one of the way to secure the connection is to use a public/private SSH key so no password is transmitted over the network and it can prevent against brute force attack.
I’ll admit up front – it’s embarrassingly late for me to have discovered screen.

In short, screen gives you the equivalent of the “workspaces” you find in Gnome, KDE, and other desktop environments, but for the command line.

There was not really a grave malicious intent on the side of the hacker except that he just wanted the people–whose iPhones were hacked–to know how vulnerable their gadgets were and he wanted them to pay 5 Euros to gain security for their iPhones. The hacker took advantage of the known root password (i.e. alpine) to get into jailbroken iPhones.

Wouldn’t it be great if all the Internet connection in the World are secure and encrypted and you don’t have to worry about hackers sniffing your data in the network? Apparently, that does not exist in the real world. Most of the time, when you are using a public network, you are exposing yourself to thousands of hackers who are waiting for you to hand over your confidential data to them.
In my post two weeks ago, I introduced you to KDE’s
