SSH tricks

Filed under
HowTos

SSH (secure shell) is a program enabling secure access to remote filesystems. Not everyone is aware of other powerful SSH capabilities, such as passwordless login, automatic execution of commands on a remote system or even mounting a remote folder using SSH! In this article we’ll cover these features and much more.

SSH works in a client-server mode. It means that there must be an SSH daemon running on the server we want to connect to from our workstation. The SSH server is usually installed by default in modern Linux distributions. The server is started with a command like /etc/init.d/ssh start. It uses the communication port 22 by default, so if we have an active firewall, the port needs to be opened. After installing and starting the SSH server, we should be able to access it remotely. A simple command to log in as user1 to the remote_server (identified by a domain name or an IP address) looks like this:

Unix and Personal Computers: Reinterpreting the Origins of Linux

So, to sum up: What Linus Torvalds, along with plenty of other hackers in the 1980s and early 1990s, wanted was a Unix-like operating system that was free to use on the affordable personal computers they owned. Access to source code was not the issue, because that was already available—through platforms such as Minix or, if they really had cash to shell out, by obtaining a source license for AT&T Unix. Therefore, the notion that early Linux programmers were motivated primarily by the ideology that software source code should be open because that is a better way to write it, or because it is simply the right thing to do, is false.

Kubuntu 15.04 With Plasma 5.3 - A Totally Different Kubuntu

The latest version of Kubuntu, 15.04, aka Vivid Vervet was released last week and it's available for free download. With this release it has become the first major distro to ship Plasma 5 as the default desktop environment. There are chances that some users may still have bad memories of Kubuntu. It's true. Back in 2011 when Ubuntu made a switch to Unity, I started looking for alternatives as their desktop environment was not suited for me. I started trying KDE-based distros and Kubuntu was among the top choices. However my experience with the distro was mixed. It was buggy, bloated and GTK apps would look ugly in it. That's when I found openSUSE and settled down with it. Read more More on KDE:

    Now, kreenshot-editor is a new Qt-based project that was inspired by Greenshot’s image editor. It is hosted on KDE playground. It focuses on the image editing task, can be invoked from command line and should also provide a resuable editor component which could be integrated into other screencapture tools. The current code is already separated into an image editor widget and the main application.
