X11 Forwarding using SSH

Filed under

As I have explained earlier, there are different ways to connect to remote servers or workstations. You can use NoMachine’s NX server or the GPL solution called FreeNX. Other tools like RealVNC or VNC provide remote control software which lets you see and interact with desktop applications across the network.

One way to enforce the traffic security is to use the SSH by the way of X11 tunneling or port forwarding. SSH was developed to replace the insecure telnet, ftp, rcp, rlogin, rsh software. FreeNX is already perfectly using this technology. In this article I will show, how to forward X11 using ssh without any additional software on the Linux site. Additionally I will explain how to run Linux applications on Windows XP clients using PuTTY and X-Deep/32.

For instructive purposes, we will use a small scenario to explain what needs to be done. There are two machines we would like to access remotely:

OpenSuse 10.2 running KDE
Debian 4.0 running Gnome

As client machines we will use OpenSuse with client ssh software but also Windows XP with Putty. From the perspective of SSH, the remote machine is the server and your local machine is the client. The workshop setup could look like this:

Roku’s 4th gen media player does 4K, gets larger, costs more

Media streaming pioneer Roku has unveiled its 4th-gen media streaming player, featuring 4K resolution, 802.11ac WiFi, a larger footprint, and a $130 price. Over the years, we’ve watched Roku evolve from being one of the first companies to offer Internet radios with its SoundBridge, to challenging Apple’s early dominance in the streaming media player market with its “Netflix box”, to pioneering HDMI-stick media players with its Streaming Stick, to becoming the “smart” in smart TVs. All these media player incarnations have run on Roku’s internally developed, Linux-based “Roku OS.” Read more

Displaylink adds Linux support for USB monitors

A few weeks ago at IDF, Displaylink released drivers for USB monitors on Linux. This has been something SemiAccurate has been asking them about since, well it has been years now. The idea is simple, transfer video data over USB rather than a dedicated video port. This requires a bit of compression, CPU load, and of course their proprietary hardware on the monitor side. That isn’t a big deal, the chips are fairly inexpensive and since you are buying a USB monitor or dock, it comes with the device out of the box. On the plus side it means your monitor will work everywhere, or at least it will now. Read more Also: Intel Compute Shaders Appear Nearly Ready For Mainline Mesa
